Abstract
The wok is made from hardened glass or glass-ceramic material so that it has a cooking surface that is easier to clean than prior art metal woks. Furthermore when it is 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 heated until it softens and then is shaped or formed into the shape of the wok, optionally ceramicized and cooled.
