What Is Tempered Glass?

Tempered glass (Tempered glass/Reinforced glass) Glass with compressive stress on the surface. Also known as strengthened glass. The tempering method was used to strengthen the glass, which began in France in 1874.
On March 15, 2024, the 2024 CCTV 3.15 Gala exposed the practice of using ordinary tempered glass with fireproof labels and selling it as fireproof glass.
Tempered glass (Tempered glass/Reinforced glass) is a safety glass. Tempered glass is actually a prestressed glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby increasing the bearing capacity and enhancing the glass's own wind pressure resistance, cold and heat resistance, impact resistance, etc. Be careful to distinguish it from fiberglass.
