Abstract
A protective for a stove plate of an electric range comprises a heat-resistant aluminum foil into which bulges have been embossed corresponding to the heating units. The embossing is carried out by hand by laying a piece of foil on the stove plate and pressing the foil on and around the heating units. Stripes of a temperature-indicating salt, such as NH.sub.4 MnP.sub.2 O.sub.7, which change color at a predetermined temperature are preferably applied to the foil to give visual indication of over-heating.

A protective cover for an electric range having a stove plate and circular electric heating units comprising:
- a piece of flexible heat resistant metal foil having good heat conductivity substantially covering said stove plate and said heating units;
- bulges in said metal foil around said units and conforming to the shape thereof to prevent said protective cover from slipping on said plate during use and to enclose said heating units to reduce heat losses therefrom;
- and,
- at least one strip of a temperature indicating salt of a kind which changes color at a temperature of approximately 400.degree. C so that said strip of salt extends over said heating units.
A protective cover for an electric range having a stove plate and circular electric heating units comprising:
- a piece of flexible heat resistant metal foil having good heat conductivity substantially covering said stove plate and said heating units;
- bulges in said metal foil around said units and conforming to the shape thereof to prevent said protective cover from slipping on said plate during use and to enclose said heating units to reduce heat losses therefrom;
- and,
- grooves in said piece of metal foil between said bulges and the ends of said piece of metal foil to catch spills from the top of the stove.
