A surface compression of over 10,000 PSI(69MPa) impacts about five times the impact and mechanical strength of annealed glass of the same thickness.
Tempered Safety Glass will resist temperatures of up to approximately 295C. In a range from - 20 C to 300C.
When broken, tempered glass become small granules, which will not exert substantial hurt to human body.
Tempered safety glass may contain some minor visual imperfection introduced through heating.
