Mica-glass is actually a mineral that comes in thin translucent sheets and can be cut with scissors, yet is able to withstand immense temperatures beyond what all glass can handle. Mica is mostly used in antique wood and coal stoves, arranged in small vertical strips. Mica glass has a beautiful appearance like clear plastic or cellophane, yet it withstands temperatures in upwards of 1800° F, making it the most heat tolerant mineral material that we carry.
