[10] It continues to expand the nearby research and development facility, as well as operations associated with catalytic converters and diesel engine filter product lines.

The company moved again to its ultimate home and eponym, the city of Corning, New York, in 1868, under leadership of the founder's son, Amory Houghton, Jr.

[13] The California Institute of Technology's 200-inch (5.1 m) telescope mirror at Palomar Observatory was cast by Corning during 1934–1936, out of low expansion borosilicate glass.

[14] In 1932, George Ellery Hale approached Corning with the challenge of fabricating the required optic for his Palomar project.

[16] This toughened glass had a chemically hardened outer layer, and its manufacture incorporated an ion exchange and a "fusion process" in special furnaces that Corning built in its Christiansburg, Virginia facility.

[15] After being installed as side glass in a limited run of 1968 Plymouth Barracudas and Dodge Darts, Chemcor windshields debuted on the 1970 model year Javelins and AMXs built by American Motors Corporation (AMC).

[17] As there were no mandatory safety standards for motor vehicle windshields, the larger automakers had no financial incentive to change from the cheaper existing products.

Due to a number of factors, the exact nature of which are subject to dispute, this project was considered a steep loss in profit and productivity.

The company also entered the photonics market, investing heavily with the intent of becoming the leading provider of complete fiber-optic systems.

Failure to succeed in photonics and the collapse in 2000 of the dot-com market had a major impact on the company, and Corning stock plummeted to $1 per share.

[23] The company continues to produce optical fiber and cable for the communications industry at its Wilmington and Concord plants in North Carolina.

It is also a major manufacturer of ceramic emission control devices for catalytic converters in cars and light trucks that use gasoline engines.

[citation needed] In 2007, Corning introduced an optic fiber, ClearCurve, which uses nanostructure technology to facilitate the small radius bending found in FTTX installations.

[citation needed] Corning is engaged in research and development on green lasers, mercury abatement, microreactors, photovoltaics, and silicon on glass.

Although the company has long been publicly owned, James R. Houghton, great-great-grandson of the founder, served as chairman of the board of directors from 2001 to 2007.

Corning invented and produced Pyrex, CorningWare and Visions Pyroceram glass-ceramic cookware, and Corelle durable glass dinnerware.

[35] In February 2011, Corning acquired MobileAccess Networks, an Israeli company that develops Distributed antenna systems, which are often used by universities, stadiums and airports to ensure seamless wireless coverage throughout a facility.
