Tempered glass 
 Tempered glass is tempered by the glass furnace heated to near the softening point, and then rapid and uniform cooling, cooling its surface to form a uniform, uniform in its surface compressive stress, while the internal tensile stress is formed so that the mechanical strength improved, improved the glass wind pressure and impact resistance, improved thermal shock resistance of glass.
