Corning Ware, also written CorningWare, was originally a brand name for a unique glass-ceramic (Pyroceram) cookware resistant to thermal shock.
It was first introduced in 1958 by Corning Glass Works (later Corning Inc.) in the United States. The brand was later spun off with the sale of the Corning Consumer Products Company subsidiary (now known as Corelle Brands of Rosemont, Illinois).
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.
CorningWare is sold worldwide, and it is popular in North America, Asia, and Australia.
