Curved and Flat Thermally Toughened Glass

Toughened glass, also known as tempered glass, is manufactured using a fast heating and quenching process. The glass is heated up to 640ºC, curved by oven rollers, and then quenched or cooled rapidly.

This process introduces stresses in the glass, improving its overall material strength.

Heat strengthened glass is very similar and produced in the same oven, but quenched more slowly.

The difference of BCE tempered is the flatness of its surfaces, the outstanding quality of the edges plus the low anisotropy and low number of roller waves.
