Tempered glass are made by forming compressive stress on the surface of the glass by heating the glass up to its intenerating temperature and then make the glass uniform cooling quickly. During the process of cooling, the exterior part of the glass is solidified because of the rapid cooling, while the interior part of the glass shrinks because of slow cooling, then forming compressive stress on the surface of the glass and tensile stress inside the glass, thus improving the intensity and heat stability of the glass.

Safety performance: Glass will appearance hurtless obtuse angles when breakage.

Strength performance:
Four times more than ordinary glass.

Heat stability performance:

Three times more than ordinary glass, could bear the temperature

change about 200°C .
