Tempered slass, Heat Soak Test, Heat Strengthen Glass

Tempered glass (also called toughened glass) is an extremely strong glass,it is produced by heating annealed glass in a furnace to 620 degree centigrade.  
Progressing from the furnace, the glass is rapidly cooled with jets of cold air, inducing compressive stresses to the surface while the center remains tensile. 

Fetures:
1.Tempered glass is four to five times stronger than its equivalent thickness of annealed glass.
2.Once breakage occurs, the glass disintegrates into small cubical fragments, which are relatively harmless to human body.
3.It withstands abrupt temperature change of 220 Centigrade.
