HARDENED GLASS OR GLASS-CERAMIC COOKING VESSEL FORMED AS A WOK, AND METHOD OF MAKING SAME

摘要

The hardened borosilicate glass or glass-ceramic cooking vessel in the form of a wok has a cooking surface that is easier to clean than prior art metal woks. Furthermore when it heated a better temperature distribution for cooking is produced and it can be universally heated either by a radiantly heated body or an atmospheric gas burner. The method of making the wok starts with a glass blank or piece of borosilicate glass, which is then heated until it softens and shaped or formed into the shape of the wok, optionally ceramicized and cooled to form the wok.
