High strength monolithic brilliant potassium fireproof glass (chemical fireproof glass) is a new type of functional building material, which has good light transmission and fire retardant properties. In daily life, as transparent as ordinary glass, chemical tempered layer after fire can prevent flame spread and heat transfer, confine the fire to a small area near the ignition point, play a role in fire prevention, and still maintain good fire resistance and flame retardancy at 1200 C.
