Abstract
A bottom electric heating element for an oven wherein the electric heating element is positioned in a recessed portion in the oven bottom and comprises at least one corrugated ribbon of conductive material partially embedded in an insulating base. A glass panel is positioned over the recessed portion and on a compressible heat resistant gasket. The glass panel is transparent or semi-transparent, high temperature resistant and high impact resistant. A frame extends around the glass panel and fastens it to the oven bottom while partially and resiliently compressing the gasket to support the glass panel.
