Stove Window Mica
Mica is a silicate mineral that is mined from the earth that breaks off into sheets because of its chemical structure. The mica sheets are dense, resistant to heat and when used in stoves are about 1mm or less thick and this quality makes mica appropriate as a substitute for glass in stove windows.
Because of its chemical structure, mica windows can separate even further then the sheets our windows come in, so do not attempt to separate the layers, as this will compromise the sheet.
