                                ($.50 par value)

     This  prospectus  relates to the resale,  from time to time, by the Corning
Incorporated  Retirement Master Trust (the "Trust") created as a part of, and on
behalf of, the Corning  Incorporated Pension Plan (the "Plan"), of shares of our
common stock,  par value $.50 per share. We have been authorized by our Board of
Directors to make  voluntary  contributions  of up to  10,000,000  shares of our
common  stock to the Trust.  The  shares of our common  stock will be issued and
contributed,  from  time to  time,  by us to the  Trust to fund  certain  of our
obligations to the Plan.

     Our common stock is listed on the New York Stock  Exchange under the symbol
"GLW." On July 29, 2005,  the closing price of our common stock,  as reported on

     The shares,  when  issued,  may be sold,  from time to time,  in  brokerage
transactions   on  the  New  York  Stock  Exchange,   in  privately   negotiated
transactions,  or otherwise.  These sales may be for negotiated prices or on the
open market at prevailing  market prices. We will not receive any portion of the
proceeds of the sale of the common stock offered by this  prospectus and we will
bear all expenses  incident to registration of the common stock.  The Trust will
be responsible for expenses incurred in selling the common stock, which expenses
may include,  among other things,  underwriting  discounts,  brokerage  fees and
commissions.

                                  RISK FACTORS

Set forth below are some of the  principal  risks and  uncertainties  that could
cause our actual business results to differ materially from any  forward-looking
statements  or other  projections  contained  in this  Prospectus.  In addition,
future  results  could be  materially  affected by general  industry  and market
conditions,  changes in laws or  accounting  rules,  general  U.S.  and non-U.S.
economic  and  political  conditions,  including  a  global  economic  slowdown,
fluctuation of interest rates or currency exchange rates,  terrorism,  political
unrest  or  international  conflicts,  political  instability  or  major  health
concerns,  natural  disasters  or other  disruptions  of expected  economic  and
business conditions.  These risk factors should be considered in addition to our
cautionary  comments concerning  forward-looking  statements in this Prospectus,
including  statements  related to  markets  for our  products  and trends in our
business  that  involve  a  number  of risks  and  uncertainties.  Our  separate
statement labeled Forward-Looking Statements should be considered in addition to
the statements below.

Our  sales  could be  negatively  impacted  if one or more of our key  customers
substantially reduce orders for our products

     Our customer base is relatively  concentrated  with 10 or fewer significant
customers  accounting for a high  percentage  (greater than 50%) of net sales in
most of our businesses.  However,  no individual customer accounts for more than
10% of consolidated sales.

     Our Display Technologies,  Telecommunications,  Environmental Technologies,
and Life  Sciences  segments  have  concentrated  customer  bases.  If we lose a
significant  customer in any of these businesses,  or if one or more significant
customers  reduce  orders,  our sales could be  negatively  impacted.  Corning's
Display  Technologies  segment  manufactures  and sells  glass  substrates  to a
concentrated  customer base comprised of LCD panel makers  primarily  located in
Japan  and  Taiwan.  The  most  significant   customers  in  these  markets  are
AU Optronics  Corp.,  Chi Mei  Optoelectronics  Corp.,  Hannstar  Display Corp.,
Quanta Display Inc.,  Sharp  Corporation,  and Toppan CFI (Taiwan) Co., Ltd. For
the six months ended June 30, 2005, these LCD customers accounted for 74% of the
Display  Technologies  segment sales. In addition,  Samsung Corning  Precision's
sales  were also  concentrated,  with three LCD panel  makers in Korea  (Samsung
Electronics  Co., Ltd., LG Philips LCD Co., and BOE Hydis  Technology Co., Ltd.)
accounting for 87% of sales for the six months ended June 30, 2005.

     Although the sale of LCD glass  substrates  has  increased  from quarter to
quarter  in 2005,  there can be no  assurance  that  this  positive  trend  will
continue.  Our customers are LCD panel makers, and as they switch to larger size
glass,  the  pace  of  their  orders  may be  uneven  while  they  adjust  their
manufacturing processes and facilities.  Additionally,  consumer preferences for
panels of  differing  sizes,  or price or other  factors,  may lead to pauses in
market  growth from time to time.  There is further risk that our  customers may
not be able to maintain  profitable  operations or access sufficient  capital to
fund ongoing expansions, which may limit their pace of orders to us.

     Our  Telecommunications  segment  customers'  purchases of our products are
affected  by  their  capital  expansion  plans,   general  market  and  economic
uncertainty and regulatory  changes,  including  broadband  policy.  For the six
months  ended  June  30,  2005,   one   customer   accounted   for  17%  of  our
Telecommunications  segment sales,  and 10 customers  accounted for 53% of total
segment sales. Sales in the  Telecommunications  segment continue to be impacted
by  Verizon's  fiber-to-the-premises  project.  




Fiber-to-the-premises  sales to  Verizon  are  dependent  on  Verizon's  planned
targets for homes passed and connected. Changes in Verizon's deployment plan, or
additional  reductions  in  their  inventory  levels  of   fiber-to-the-premises
products, could adversely affect future sales.

     In the Environmental  Technologies segment,  sales of our ceramic substrate
and filter  products for automotive and diesel  emissions and pollution  control
fluctuate with production and sales of automobiles  and other vehicles,  as well
as changes in  governmental  laws and  regulations  for air quality and emission
controls. Sales in our Environmental  Technologies segment are primarily to four
manufacturers of emission control systems who then sell to automotive and diesel
engine  manufacturers.  A portion of our  automotive  products  are sold to U.S.
engine  manufacturers,  and as a result,  our future  sales  could be  adversely
impacted by slowdowns in automotive production by these manufacturers.

     Sales in our Life Sciences segment in 2004 were primarily through two large
distributors to government entities, pharmaceutical and biotechnology companies,
hospitals,  universities  and other  research  facilities.  One of Life Sciences
primary  distributors  changed its business strategy,  and Corning notified this
distributor that it would not renew its existing distribution  agreement,  which
expired in April 2005. We are actively  working to transition  the sales through
this  distributor to our remaining  primary  distributor  and other existing and
developing  channels.  However,  this change will likely  adversely impact sales
volumes in the short term. For the full year, sales may be adversely impacted by
approximately  10% as a result of this change in our distribution  channel.  For
the six months ended June 30, 2005, our remaining primary distributor  accounted
for 41% of total segment sales.

If we do not  successfully  adjust  our  manufacturing  volumes  and fixed  cost
structure,  or achieve  manufacturing  yields or sufficient product reliability,
our operating results could suffer, and we may not achieve  profitability levels
anticipated

     We are investing  heavily in additional  manufacturing  capacity of certain
businesses,  including  forecasted 2005 capital spending of $1.1 billion to $1.2
billion to expand our liquid  crystal  display  glass  facilities in response to
anticipated  increases  in customer  demand and  approximately  $150  million in
anticipation  of the emerging market for diesel emission  control  systems.  The
speed  of  constructing  the new  facilities  presents  challenges.  We may face
technical and process issues in moving to commercial production capacity.  There
can be no assurance that Corning will be able to pace its capacity  expansion to
the actual demand. While the LCD industry has grown rapidly, it is possible that
glass manufacturing capacity may exceed customer demand during certain periods.

     The  manufacturing  of our  products  involves  highly  complex and precise
processes,  requiring  production in highly  controlled and clean  environments.
Changes  in  our  manufacturing  processes  or  those  of  our  suppliers  could
significantly reduce our manufacturing  yields and product reliability.  In some
cases,  existing  manufacturing  may be  insufficient  to achieve  the volume or
requirements  of our  customers.  We will  need  to  develop  new  manufacturing
processes and  techniques to achieve  targeted  volume,  pricing and cost levels
that will permit  profitable  operations.  While we continue to fund projects to
improve  our  manufacturing   techniques  and  processes,  we  may  not  achieve
satisfactory cost levels in our manufacturing activities that will fully satisfy
our yield and margin targets.



Our future  operating  results  depend on our ability to  purchase a  sufficient
amount of materials, parts and components to meet the demands of our customers.

     Our ability to meet customer  demands  depends,  in part, on our ability to
obtain timely and adequate delivery of materials,  parts and components from our
suppliers and our internal  manufacturing  capacity. We may experience shortages
that could adversely  affect our  operations.  Although we work closely with our
suppliers to avoid these types of shortages,  there can be no assurances that we
will not encounter  these  problems in the future.  Furthermore,  certain of our
components  are available only from a single source or limited  sources.  We may
not be able to find  alternate  sources  in a  timely  manner.  A  reduction  or
interruption  in supplies,  or a  significant  increase in the price of supplies
could have a material adverse effect on our businesses.

We have incurred, and may in the future incur,  restructuring and other charges,
the amounts of which are difficult to predict accurately

     We have recorded several charges for  restructuring,  impairment of assets,
and the  write-off of cost and equity based  investments.  It is possible we may
record  additional  charges  for  restructuring  or other asset  impairments  if
additional actions become necessary to align costs to a reduced level of demand,
or  respond to  increased  competition,  regulatory  actions,  or other  factors
impacting our businesses.

If the  markets for our  products  do not  develop and expand as we  anticipate,
demand for our products may decline,  which would negatively  impact our results
of operations and financial performance

     The  markets  for  our  products  are  characterized  by  rapidly  changing
technologies,  evolving industry  government  standards and frequent new product
introductions.  Our success is expected to depend,  in substantial  part, on the
timely and successful introduction of new products, upgrades of current products
to comply with emerging industry  government  standards,  our ability to acquire
technologies  needed to remain  competitive and our ability to address competing
technologies  and products.  In addition,  the following  factors related to our
products and the markets for them, if not achieved, could have an adverse impact
on our results of operations and financial performance:

     o    our ability to introduce leading products such as glass substrates for
          liquid  crystal  displays,  optical  fiber and cable and  hardware and
          equipment,  and  environmental  substrate  products  that can  command
          competitive prices in the marketplace;
     o    our  ability to  maintain  or achieve a  favorable  sales mix of large
          generation sizes of liquid crystal display glass;
     o    our ability to  continue  to develop new product  lines to address our
          customers'  diverse needs within the several  market  segments that we
          participate in, which requires a high level of innovation,  as well as
          the accurate anticipation of technological and market trends;
     o    our  ability  to  develop  new   products  in  response  to  favorable
          government regulations and laws driving customer demand,  particularly
          environmental  substrate  diesel filter products in the  Environmental
          Technologies   segment   and   Telecommunications   segment   products
          associated with fiber-to-the-premises;
     o    continued strong demand for notebook computers;
     o    the rate of  substitution  by  end-users  purchasing  LCD  monitors to
          replace cathode ray tube monitors;
     o    the rate of growth in purchases of LCD  televisions  to replace  other
          technologies;



     o    fluctuations  in  inventory  levels in the supply  chain of  LCD-based
          consumer electronics and fiber-to-the-premises products;
     o    the ability to reallocate LCD glass to other  customers in response to
          canceled orders; or
     o    the rate of growth  of the  fiber-to-the-premises  build-out  in North
          America.

We face pricing pressures in each of our leading businesses that could adversely
affect our results of operations and financial performance

     We periodically face pricing pressures in each of our leading businesses as
a result of intense  competition,  emerging new technologies,  or over-capacity.
While we will work toward reducing our costs to respond to the pricing pressures
that may  continue,  we may not be able to achieve  proportionate  reductions in
costs.  As a result  of  overcapacity  and the  current  economic  and  industry
downturn in the Telecommunications segment, pricing pressures continued in 2005,
particularly  in our optical fiber and cable  products.  We  anticipate  pricing
pressures  will continue into 2006 and beyond.  Increased  pricing  pressure may
develop in our Display  Technologies  segment as our customers  strive to reduce
their costs and our competitors strive to expand production.

We have  incurred,  and may in the future incur,  goodwill and other  intangible
asset impairment charges

     At June 30, 2005, Corning had goodwill of $277 million and other intangible
assets of $106  million.  While we believe the  estimates  and  judgments  about
future  cash flows used in the  goodwill  impairment  tests are  reasonable,  we
cannot provide assurance that future impairment  charges will not be required if
the expected  cash flow  estimates as  projected by  management  do not occur or
change based on market conditions.

We may be limited in our ability to obtain  additional  capital on  commercially
reasonable terms

     Although we believe  existing cash,  short-term  investments  and borrowing
capacity,  collectively,  provide adequate  resources to fund ongoing  operating
requirements,  we may be  required  to  seek  additional  financing  to  compete
effectively in our markets.  Our public debt ratings affect our ability to raise
capital and the cost of such capital.  Our ratings as of July 29, 2005 were BBB-
from both Fitch,  Inc.  and  Standard & Poor's,  a division  of the  McGraw-Hill
Companies,  Inc. and Ba2 from Moody's Investors Service, a subsidiary of Moody's
Corporation.  Any  downgrades  may increase our  borrowing  costs and affect our
ability to access the debt capital markets.

     We are subject under our revolving  credit facility to financial  covenants
that  require  us to  maintain a ratio of total  debt to  capital  and  interest
coverage ratio, as defined under the revolving credit facility.  These covenants
may limit our ability to borrow  funds.  Future  losses or  significant  charges
could materially  affect these ratios,  which may reduce the amounts we are able
to borrow under our revolving credit facility.

If our products or materials purchased from our suppliers experience performance
issues, our business will suffer

     Our  business   depends  on  the   production  of  excellent   products  of
consistently  high  quality.  To this end,  our  products,  including  materials
purchased from our suppliers, are tested for quality both by us and



our customers. Nevertheless, our products are highly complex, and our customers'
testing  procedures  are limited to  evaluating  our  products  under likely and
foreseeable failure scenarios. For various reasons (including, among others, the
occurrence of performance problems  unforeseeable in testing),  our products and
materials  purchased  from  our  suppliers  may  fail to  perform  as  expected.
Performance  issues could result from faulty design or problems in manufacturing
or testing.  We have experienced such performance  issues in the past and remain
exposed  to  such  performance  issues.  In some  cases,  product  redesigns  or
additional  capital  equipment may be required to correct a defect. In addition,
any significant or systemic  product failure could result in customer  relations
problems and harm the future sales of our products.

We face intense competition in most of our businesses

     We  expect  that  we  will  face  additional   competition   from  existing
competitors,  low  cost  manufacturers  and new  entrants.  Because  some of the
markets in which we compete have been historically characterized by rapid growth
and are  characterized by rapid technology  changes,  smaller niche and start-up
companies,  or companies  with lower  operating  costs may become our  principal
competitors in the future.  We must invest in research and  development,  expand
our  engineering,  manufacturing  and  marketing  capabilities,  and continue to
improve customer service and support in order to remain  competitive.  We cannot
provide  assurance  that we will be able to maintain or improve our  competitive
position.

We may experience difficulties in enforcing our intellectual property rights and
we may be subject to claims of infringement of the intellectual  property rights
of others

     We may encounter  difficulties  in  protecting  our  intellectual  property
rights or obtaining  rights to  additional  intellectual  property  necessary to
permit us to continue or expand our  businesses.  We cannot  assure you that the
patents that we hold or may obtain will provide  meaningful  protection  against
our  competitors  or  competitive  technologies.  Litigation may be necessary to
enforce our intellectual  property  rights,  to protect our trade secrets and to
determine  the  validity  and scope of our  proprietary  rights.  Litigation  is
inherently  uncertain and the outcome is often  unpredictable.  Other  companies
hold patents on technologies used in our industries and are aggressively seeking
to expand, enforce and license their patent portfolios.

     The  intellectual  property  rights of others could  inhibit our ability to
introduce new products.  We are, and may in the future be,  subject to claims of
intellectual  property  infringement or misappropriation that may result in loss
of revenue or require us to incur substantial  costs. We cannot assure you as to
the outcome of such claims.

Current or future  litigation  may harm our  financial  condition  or results of
operations

     Pending,   threatened   or  future   litigation   is  subject  to  inherent
uncertainties. Our financial condition or results of operations may be adversely
affected by unfavorable outcomes, expenses and costs exceeding amounts estimated
or  insured.  In  particular,  we have been  named as a  defendant  in  numerous
lawsuits  against PCC and several other  defendants  involving  claims  alleging
personal  injury from exposure to asbestos.  As described in Legal  Proceedings,
our negotiations with the  representatives of asbestos claimants have produced a
tentative  settlement,  but certain  cases may still be litigated  and the final
approval of the tentative  settlement  is subject to a number of  uncertainties.
Final approval of a global  settlement  through the PCC  bankruptcy  process may
impact the results of operations for the period in



which such costs,  if any, are  recognized.  Total  charges of $567 million have
been incurred through June 30, 2005;  however,  additional  charges are possible
due to the  potential  fluctuation  in the  price  of our  common  stock,  other
adjustments in the proposed settlement, and other litigation factors.

We face risks related to our international operations and sales

     We have customers and significant  operations,  including manufacturing and
sales,  located  outside the U.S.  We have large  manufacturing  operations  for
liquid crystal display glass  substrates in the Asia-Pacific  region,  including
equity  investments  in  companies  operating  in South  Korea that make  liquid
crystal display glass and in China that make  telecommunications  products,  and
several  significant  customers are located in this region. As a result of these
and other international operations, we face a number of risks, including:

o    geographical concentration of our factories and operations;
o    major health concerns such as Severe Acute Respiratory Syndrome (SARS);
o    difficulty of effectively managing our diverse global operations;
o    change in regulatory requirements;
o    tariffs, duties and other trade barriers including anti-dumping duties;
o    undeveloped legal systems; and
o    political and economic instability in foreign markets.

     Any of these  items  could  cause  our  sales  and/or  profitability  to be
significantly reduced.

We face risks through our equity method  investments in companies that we do not
control

     Corning's net income includes  significant equity in earnings of associated
companies.  For the six months  ended June 30,  2005,  we have  recognized  $338
million of equity  earnings,  of which $310  million  came from our two  largest
investments; Dow Corning Corporation (which makes silicone products) and Samsung
Corning  Precision  Glass Co., Ltd.  (which makes liquid crystal display glass).
Samsung Corning Precision is located in the Asia-Pacific region and, as such, is
subject  to  those  geographic  risks  referred  to  above.  With  50% or  lower
ownership,  we do not control such equity  companies  nor their  management  and
operations.  Performance of our equity  investments may not continue at the same
levels in the future. During 2003, we recognized charges associated with Samsung
Corning Co., Ltd. (our 50% equity method  investment that makes glass panels and
funnels for conventional  televisions),  which recorded  significant fixed asset
impairment  charges.  As the conventional  television  market will be negatively
impacted by strong  growth in the LCD glass market,  it is  reasonably  possible
that Samsung Corning Co., Ltd. may incur additional  restructuring or impairment
charges or net operating losses in the future.

We face risks due to foreign currency fluctuations

     Because we have  significant  customers  and  operations  outside the U.S.,
fluctuations in foreign currencies, especially the Japanese yen and Euro, affect
our sales and profit levels.  Foreign  exchange rates may make our products less
competitive in countries where local currencies decline in value relative to the
dollar.  Sales in our Display  Technologies  segment are denominated in Japanese
yen. For the six months ended June 30, 2005,  the Display  Technologies  segment
represented  34% of Corning's  sales.  Based on the expected sales growth of the
Display  Technologies   segment,  our  exposure  to  currency   fluctuations  is
increasing.  Although we hedge significant transaction risk, we do not currently
hedge translation risk.



If the  financial  condition of our customers  declines,  our credit risks could
increase

     We have experienced,  and in the future may experience,  losses as a result
of our inability to collect our accounts receivable, as well as the loss of such
customer's  ongoing  business.  If our  customers  fail  to meet  their  payment
obligations to us,  including  deposits due under long-term  purchase and supply
agreements in our Display Technologies segment, we could experience reduced cash
flows and losses in excess of amounts  reserved.  As of June 30, 2005,  reserves
for trade receivables totaled approximately $27 million.

We may not have adequate insurance coverage for claims against us

     We face the risk of loss resulting from, and adverse  publicity  associated
with, product liability, securities, fiduciary liability, intellectual property,
antitrust, contractual,  warranty, fraud and other lawsuits, whether or not such
claims are valid. In addition, our product liability,  fiduciary,  directors and
officers,  property and  comprehensive  general  liability  insurance may not be
adequate to cover such claims or may not be  available  to the extent we expect.
Our insurance costs have increased and may increase further.  We may not be able
to get  adequate  insurance  coverage  in the  future  at  acceptable  costs.  A
successful claim that exceeds or is not covered by our policies could require us
to pay substantial  sums. Some of the carriers in our excess insurance  programs
are in  liquidation  and may not be able to  respond  if we should  have  claims
reaching  into  excess  layers.  The  financial  health  of other  insurers  may
deteriorate  and these  insurers  may not be able to respond  if we should  have
claims  reaching into excess layers.  In addition,  we may not be able to insure
against  certain risks or obtain some types of  insurance,  such as terrorism or
war insurance.

We cannot assure you that our stock price will not decline

     The market price of our common stock may  fluctuate in response to a number
of factors,  some of which are beyond our control. The price of our common stock
may be impacted  by,  among  other  things,  our  operational  performance,  the
expectations of the market and our ability to meet those expectations,  industry
and general market  conditions.  As a result of these or other market conditions
or changes,  there can be no  assurance  that the price of our common stock will
not decline in the future.

Future sales of our common stock could lower the price of our common stock

     After this  offering,  we will have  1,482,914,492  shares of common  stock
outstanding,  assuming no  exercise of  outstanding  options.  The shares  being
offered  in this  offering  will be  freely  tradable  under  federal  and state
securities laws, to the extent that they are not purchased by our affiliates. In
the  future,  we may issue  additional  shares to our  employees,  directors  or
consultants,  or in connection with corporate  alliances or acquisitions,  or in
follow-on  offerings to raise  additional  capital.  As such,  the issuance of a
substantial  number of shares of our  common  stock in the public  market  could
occur at any time.  The  issuance of  additional  shares could reduce the market
price of our common stock.



                                 USE OF PROCEEDS

     The proceeds  from the sale of the shares being offered are for the account
of the Trust.  Corning  will not receive any portion of the proceeds of the sale
of the  common  stock  offered  by this  prospectus  and  Corning  will bear all
expenses  incident  to  registration  of the  common  stock.  The Trust  will be
responsible  for expenses  incurred in selling the common stock,  which expenses
may include,  among other things,  underwriting  discounts,  brokerage  fees and
commissions.

                      DESCRIPTION OF CORNING CAPITAL STOCK

Authorized Capital Stock

     Corning's  authorized  capital stock  consists of  3,800,000,000  shares of
common stock, $.50 par value, and 10,000,000 shares of preferred stock, $100 par
value.

Common Stock

     As of July 15, 2005, there were 1,472,914,492 outstanding shares of Corning
common  stock held by  approximately  21,900  holders of record.  The holders of
Corning  common  stock are  entitled  to one vote for each share on all  matters
submitted to a vote of shareholders  and do not have  cumulative  voting rights.
Corning's board of directors is classified  into three classes of  approximately
equal  size,  one of which is  elected  each  year.  Accordingly,  holders  of a
majority  of the  Corning  common  stock  entitled  to vote in any  election  of
directors may elect all of the directors  standing for election.  The holders of
Corning  common  stock are  entitled  to share  ratably in all assets of Corning
which are legally  available  for  distribution,  after payment of all debts and
other  liabilities  and  subject to the prior  rights of any  holders of Corning
preferred  stock then  outstanding.  Effective July 9, 2001,  Corning's board of
directors  determined  that no future  dividends  will be paid.  The  holders of
Corning common stock have no preemptive, subscription,  redemption or conversion
rights.  The  outstanding  shares of  Corning  common  stock are fully  paid and
nonassessable.  The rights,  preferences  and  privileges  of holders of Corning
common stock are subject to the rights of the holders of shares of any series of
Corning preferred stock which Corning may issue in the future.

Preferred Stock

     Corning has designated  2,400,000 shares of its preferred stock as Series A
junior participating  preferred stock and 5,750,000 shares as Series C mandatory
convertible preferred stock. As of July 15, 2005, there were 615,550 outstanding
shares of Series C  mandatory  convertible  preferred  stock.  No other  Corning
preferred  stock is  outstanding.  Series A  preferred  stock  is  reserved  for
issuance  upon  exercise  of the rights  distributed  to the  holders of Corning
common stock pursuant to the Corning Rights Agreement referred to below.

     Corning's board of directors has the authority, without further shareholder
approval,  to  create  other  series  of  preferred  stock,  to issue  shares of
preferred  stock in such  series  up to the  maximum  number  of  shares  of the
relevant class of preferred stock authorized, and to fix the dividend rights and
terms, conversion rights and terms, voting rights,  redemption rights and terms,
liquidation  preferences,  sinking funds and any other rights,  preferences  and
limitations  applicable  to each such  series of Corning  preferred  stock.  The
purpose of authorizing Corning's board of directors to determine such rights and
preferences  is to  eliminate  delays  associated  with a  shareholder  vote  on
specific  issuances.  The issuance of Corning  preferred stock,  while providing
flexibility  in  connection  with  possible  acquisitions  and  other  corporate
purposes,  could,  among  other  things,  adversely  affect the voting  power of
holders of Corning common stock and, under certain  circumstances,  make it more
difficult for a third party to gain control of Corning.

Rights Agreement

     Corning has  adopted a Rights  Agreement,  dated as of June 5, 1996,  which
provides for the




issuance of one right to the holder of each share of Corning  common stock.  Ten
days after any person or group  acquires or announces  its  intention to acquire
20% or more of the  outstanding  Corning  common stock,  each Corning right will
entitle the holder,  other than the acquiring  person or group,  to purchase one
one-hundredth  of a share of Series A preferred  stock,  at an exercise price of
$41.67 subject to certain antidilution adjustments.

     If a person or group  announces its intention to acquire 20% or more of the
outstanding  Corning common stock or if Corning is acquired in a merger or other
business  combination or sells 50% or more of its assets or earning power,  each
Corning right,  other than a Corning right  beneficially  owned by the acquiring
person or group, which will be void, will entitle the holder to purchase, at the
exercise price,  common stock of the acquiring  person or group having a current
market value of two times the exercise price of the right.  Prior to a person or
group acquiring 50% or more of the outstanding  Corning common stock,  Corning's
board of  directors  may also elect to issue a share of Corning  common stock in
exchange for each Corning right, other than Corning rights held by the acquiring
person or group.

     The Corning rights expire on July 15, 2006,  unless this expiration date is
extended or the Corning  rights are exchanged or redeemed by Corning before such
date. Prior to an announcement by a person or group of its intent to acquire 20%
or more of the outstanding Corning common stock,  Corning may redeem the Corning
rights in whole,  but not in part, for $.01 per Corning  right,  or it may amend
the Corning  Rights  Agreement  in any way without the consent of the holders of
the Corning rights.

Transfer Agent and Register

     The  transfer   agent  and  registrar  for  the  Corning  common  stock  is
Computershare Investor Services LLC in Chicago, Illinois.




                               SELLING SHAREHOLDER

     The Corning  Incorporated  Retirement  Master Trust (the "Trust") is a part
of, and was created to hold certain assets of the Corning  Incorporated  Pension
Plan (the "Plan") in segregated  accounts.  This  prospectus  covers the resale,
from time to time, by the Trust of shares of our common stock.  The Plan and the
Trust are intended to be tax-qualified within the meaning of Sections 401(a) and
501(a) of the Internal Revenue Code of 1986, as amended (the "Code").  The Trust
is funded by individual  participant and Corning  contributions,  which are held
for the sole benefit of plan  participants and  beneficiaries  and which pay for
proper expenses of plan administration.

     JP Morgan  Chase  Bank,  N.A.  (the  "Trustee")  serves as  trustee  of the
segregated  accounts in the Trust in accordance  with a Trust Agreement dated as
of September 6, 1978 and a Master Trust  Agreement  dated as of January 1, 1986,
each as amended.

     We have  been  authorized  by our  Board  of  Directors  to make  voluntary
contributions of up to 10,000,000  shares of our common stock to the Trust on or
before December 31, 2005. We will make  contributions  to the Trust from time to
time in amounts  that are not greater  than ten percent of the total assets held
by the Trust pursuant to the Employee Retirement Income Security Act of 1974, as
amended)  ("ERISA").  Our  Board of  Directors  has  directed  that the  Trustee
promptly sell the shares of our common stock upon  contribution.  The Trustee is
responsible  for  custody  of the  shares,  and  will  be  responsible  for  the
disposition of the shares of our common stock.

     As of the date of this  prospectus,  the Trust  beneficially  owned 549,000
shares of our  common  stock.  We cannot  estimate  the  number of shares of our
common stock that the Trust will hold in the future.

     The Trustee will receive customary  compensation in its role as Trustee. It
is currently  intended that JP Morgan  Securities,  Inc. will serve as broker in
effecting  the sale of the shares of common  stock for the  Trust,  for which JP
Morgan  Securities,  Inc.  will receive  customary  compensation  for serving as
broker.  The Trustee  serves,  and may in the future serve,  as trustee for debt
securities issued or to be issued under our Indentures. The Trustee has provided
commercial  banking and other  services for us and our related  companies in the
past and may do so in the future.




                              PLAN OF DISTRIBUTION

     The  Trust  may offer the  shares  from time to time,  depending  on market
conditions and other factors,  in one or more transactions on the New York Stock
Exchange or any other  national  securities  exchange or  automated  interdealer
quotation  system on which shares of our common  stock are then listed,  through
negotiated  transactions or otherwise.  The shares will be sold at prices and on
terms then prevailing,  at prices related to the then-current market price or at
negotiated  prices.  The shares may be offered in any manner  permitted  by law,
including through underwriters,  brokers, dealers or agents, and directly to one
or more  purchasers.  Sales of the shares  may  involve:  

     o    ordinary  brokerage  transactions  and  transactions in which a broker
          solicits purchasers;

     o    block  transactions in which the broker or dealer engaged will attempt
          to sell shares as agent,  but may position and resell a portion of the
          block as principal to facilitate the transaction;

     o    purchases by a broker or dealer as principal  and resale by the broker
          or dealer for its account; or

     o    sales to  underwriters  who will acquire  shares for their own account
          and  resell  them in one or more  transactions  at fixed  prices or at
          varying prices determined at the time of sale.

     The Trust and/or  purchasers  of the shares may pay brokers and dealers for
selling  shares.  These payments may be in the form of  underwriting  discounts,
concessions or commissions. The Trust and any broker dealer who sells or assists
the Trust in selling the shares may be deemed an underwriter  within the meaning
of the Securities Act of 1933, as amended (the  "Securities  Act").  If they are
deemed to be underwriters,  any brokerage commissions or discounts may be deemed
to be underwriting  discounts and commissions  under the Securities Act. We will
file, as necessary,  a prospectus  supplement when the Trust notifies us that it
has entered into an arrangement  with an  underwriter,  broker or dealer for the
sale of  shares.  The  prospectus  supplement  will  disclose  certain  material
information, including: 

     o    the number of shares being offered;

     o    the terms of the offering;

     o    any discounts, commissions or other compensation paid to underwriters,
          brokers or dealers;

     o    the public offering price;

     o    any discounts, commissions or concessions allowed or reallowed or paid
          by any underwriters to dealers; and

     o    other material terms of the offering.

     In order to  comply  with  securities  laws of  certain  jurisdictions,  if
applicable,  the  shares  may  be  sold  in  these  jurisdictions  only  through
registered   or  licensed   brokers  or  dealers.   In   addition,   in  certain
jurisdictions, the shares may not be sold unless the shares have been registered
or qualified for sale in these 



jurisdictions,  or an exemption from  registration or qualification is available
and complied with. The Trust and any other persons participating in the sales of
the shares pursuant to this  prospectus may be subject to applicable  provisions
of the Securities  Exchange Act of 1934, as amended (the "Exchange Act") and the
rules and  regulations  under the Exchange  Act.  

     As of the  date of  this  prospectus,  there  are no  selling  arrangements
between the Trust and any  underwriter,  broker or dealer.  Rather than  selling
shares  under the  prospectus,  the Trust may also sell shares in reliance  upon
Rule 144 of the Securities  Act,  provided it meets the criteria and conforms to
the  requirements  of Rule 144.  

     We will not receive any of the proceeds  from the sale of the shares by the
Trust.  We will bear the costs of  registering  the shares under the  Securities
Act,  including the registration fee under the Securities Act,  accounting fees,
printing  fees,  fees and  disbursements  of our  counsel,  and certain fees and
disbursements  of counsel to the  Trustee.  The Trust  will be  responsible  for
underwriting  discounts,  brokerage fees and  commissions,  if any,  incurred in
connection with the sale of shares.

     We have agreed to maintain the effectiveness of the registration  statement
of which this  prospectus  is a part until the earlier of (a) the  date on which
all of the shares  registered  under the  registration  statement  of which this
prospectus  is a part are sold and (b) the one year  anniversary  of the date of
the contribution to the Trust.

     The  pension  plan is a  "pension  plan" as  defined  in ERISA.  Prohibited
transactions  under Title I of ERISA and  Section 4975 of the Code,  could arise
if,  absent an  available  exemption,  a person  or entity  which is a "party in
interest," as defined under ERISA, or a "disqualified  person," as defined under
the Code,  were to purchase  any of the shares being  offered by the Trust.  Any
such potential  purchaser  should  consult with counsel to determine  whether an
exemption is available with respect to any such purchase.




                                  LEGAL MATTERS

     The validity of the shares of our common stock is being passed on for us by
William D. Eggers,  Esq.,  Senior Vice President and General  Counsel of Corning
Incorporated.  Mr.  Eggers owns  substantially  less than 1% of the  outstanding
shares of our common stock.

directors to the corporation or its  shareholders  for damages for the breach of
any duty,  except for a breach involving  intentional  misconduct,  bad faith, a
knowing  violation  of law or receipt  of an  improper  personal  benefit or for

Item 17.  Undertakings.

     (a)  The undersigned registrant hereby undertakes

               (1)  to file,  during  any  period  in which  offers or sales are
                    being made, a post-effective  amendment to this registration
                    statement:

                    (i)  to include any prospectus  required by Section 10(a)(3)
                         of  the   Securities  Act  of  1933,  as  amended  (the
                         "Securities Act");

                    (ii) to  reflect  in the  prospectus  any  facts  or  events
                         arising after the effective  date of this  registration
                         statement (or the most recent post-effective  amendment
                         thereof)  which,  individually  or  in  the  aggregate,
                         represent a fundamental  change in the  information set
                         forth in the  registration  statement.  Notwithstanding
                         the  foregoing,  any  increase or decrease in volume of
                         securities  offered  (if  the  total  dollar  value  of
                         securities  offered  would not  exceed  that  which was
                         registered)  and any deviation from the low or high end
                         of  the  estimated   maximum   offering  range  may  be
                         reflected  in the  form of  prospectus  filed  with the
                         Commission   pursuant   to  Rule   424(b)  if,  in  the
                         aggregate, the changes in volume and price represent no
                         more than 20% change in the maximum aggregate  offering
                         price set  forth in the  "Calculation  of  Registration
                         Fee" table in the effective registration statement; and

                    (iii) to include any  material  information  with respect to
                         the plan of  distribution  not previously  disclosed in
                         this  registration  statement or any material change to
                         such information in the registration statement;

provided,  however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information  required to be included in a  post-effective  amendment  thereby is
contained  in periodic  reports  filed by the Company  pursuant to Section 13 or
Section 15(d) of the Securities  Exchange Act of 1934 (the "Exchange  Act") that
are incorporated by reference in the registration statement;

               (2)  that, for the purpose of determining any liability under the
                    Securities Act, each such post-effective  amendment shall be
                    deemed to be a new  registration  statement  relating to the
                    securities  offered  therein,   and  the  offering  of  such
                    securities  at that time  shall be deemed to be the  initial
                    bona fide offering thereof; and

               (3)  to  remove  from  registration  by means  of  post-effective
                    amendment  any  of the  securities  being  registered  which
                    remain unsold at the termination of the offering.

     (b)  The   undersigned   registrant   undertakes   that,  for  purposes  of
          determining any liability under the Securities Act, each filing of the
          Company's  annual report pursuant to Section 13(a) or Section 15(d) of
          the Exchange Act (and,  where  applicable,  each filing of an employee
          benefit plan's annual report pursuant to Section 15(d) of the Exchange
          Act) that is incorporated by reference in the  registration  statement
          shall be deemed to be a new  registration  statement  relating  to the
          securities  offered  therein,  and the offering of such  securities at
          that  time  shall be  deemed  to be the  initial  bona  fide  offering
          thereof.

                                                        II-3




     (c)  Insofar  as   indemnification   for  liabilities   arising  under  the
          Securities Act may be permitted to directors, officers and controlling
          persons of a  registrant  pursuant  to the  foregoing  provisions,  or
          otherwise,  the registrant has been advised that in the opinion of the
          Securities and Exchange  Commission  such  indemnification  is against
          public   policy  as   expressed   in  such  Act  and  is,   therefore,
          unenforceable.  In the  event  a  claim  against  the  registrant  for
          indemnification  against such liabilities (other than the payment by a
          registrant  of expenses  incurred  or paid by a  director,  officer or
          controlling person of such registrant in the successful defense of any
          action,  suit or proceeding) is asserted by such director,  officer or
          controlling  person in connection with the securities being registered
          herein,  the registrant will, unless in the opinion of its counsel the
          matter has been settled by controlling precedent, submit to a court of
          appropriate  jurisdiction the question whether such indemnification by
          it is  against  public  policy  as  expressed  in such Act and will be
          governed by the final adjudication of such issue.

                        [Corning Incorporated Letterhead]


August 1, 2005

To the Board of Directors of
Corning Incorporated

Ladies and Gentlemen:

     I am Senior Vice President and General Counsel of Corning  Incorporated,  a
New York  corporation  ("Corning"),  and am familiar  with the  preparation  and
filing of a Registration  Statement on Form S-3 (the  "Registration  Statement")
under the Securities Act of 1933, as amended (the "Securities Act"), relating to
the  proposed  sale by the Corning  Incorporated  Retirement  Master  Trust (the
"Trust") of up to 10,000,000  shares of Corning common stock, par value $.50 per
share,  form time to time,  pursuant to Rule 415 under the  Securities  Act (the
"Securities").

     In this connection,  I have examined the originals,  or copies certified to
my satisfaction,  of such corporate  records of Corning,  certificates of public
officials and officers of Corning,  and other documents as I deemed pertinent as
a basis for the opinions hereinafter expressed.

     Based upon the foregoing,  and having regard for such legal  considerations
as I have deemed relevant, I am of the opinion that:
 
     1.   Corning is a corporation duly  incorporated and validly existing under
          the laws of the State of New York;

     2.   The Securities  have been duly  authorized and, when issued by Corning
          to the Trust, will be validly issued, fully paid and non-assessable.

     My  opinions  expressed  above are  limited to the laws of the State of New
York.

     I hereby  consent  to the  filing  of this  opinion  as an  exhibit  to the
Registration  Statement  and  further  consent  to the use of my name  under the
caption "Legal Matters" in the Registration Statement.

                                                      Very truly yours,

                                                      /s/  WILLIAM D. EGGERS
 


                                                                Exhibit 23.2

                       CONSENT OF INDEPENDENT ACCOUNTANTS

     We hereby consent to the  incorporation  by reference in this  Registration
Statement  on Form S-3 of our report dated  February  22, 2005,  relating to the
financial statements,  financial statement schedule,  management's assessment of
the  effectiveness  of  internal  control  over  financial   reporting  and  the
effectiveness  of internal  control over financial  reporting,  which appears in
Corning  Incorporated's  Annual Report on Form 10-K for the year ended  December
31, 2004. We also consent to the reference to us under the heading  "Experts" in
such Registration Statement.
