Tempered Glass
Heat-strengthened glass differs from tempered glass in its surface compression, its mechanical strength isabout 1.6-2 times that of annealed glass. Heat-strengthened glass has outstanding thermal stability, and itsflatness is close to that of annealed glass and better than that of tempered glass.
