Abstract

A cooking tray is disclosed in which a carrier of tempered glass is mounted on a support surface between the support surface and the heating element. The carrier is insulated to protect it from the heat of the heating element by thermal sealing means comprising in one embodiment an intermediate ring surrounding the heating element having a layer of insulation attached to the intermediate ring. Moisture seals are also provided between the carrier and the heating element to prevent moisture from entering between the carrier and the heating element. Various alternative embodiments illustrating the concept of utilizing the carrier of tempered glass with an intermediate ring, heat insulation and moisture sealing means to permit the combination of various heating elements with a carrier of tempered glass are disclosed.
