“Sought After by Collectors”

Corning Ware is an investment, pick it up at a very reasonable price

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 Instant Brands of Downers Grove, Illinois).
