CorningWare

Corning Ware, also written CorningWare, was originally a brand name for a unique glass-ceramic (Pyroceram) cookware resistant to thermal shock.

Pyroceram has properties similar to glass and ceramic, and CorningWare was advertised as being capable of being taken from the refrigerator or freezer and used directly on the stovetop, in an oven or microwave, under a broiler, and go into a dishwasher.

In 1953 S. Donald Stookey of the Corning Research and Development Division accidentally discovered Pyroceram, a white glass-ceramic material capable of withstanding a thermal shock of up to 450 K (840 °F).

[3] Originally manufactured primarily in the US, production of Pyroceram-based Corning Ware ceased in the States with the closure of the Martinsburg, West Virginia plant.

Additional patterns have been created specifically for this market, including Bliss, Blue Elegance, Cool Pansies, Country Rose, Dainty Flora, Dandy Blossoms, Elegant City, European Herbs, Herb Country, Lilyville, Lush, Petite Trio, Plum, Salad Seasons and Warm Pansies among others.

[6] Care must be made to distinguish between Corning Ware cookware and tableware marketed under the Corelle and Pyrex brand names, as the thermal properties of the products are quite different.

Arc International, France, sells cookware that is equivalent to Corning Ware under various brand names including Arcoflam, Luminarc, and Arcoroc.

Their Octime line of glass-ceramic saucepans and casseroles were rebadged for Princess House and sold as Nouveau cookware in the US and other select regions.
