The tempering process will provide greater strength and safety to the glasses, made from the controlled heating of common glass, at an approximate temperature of 700º, and then it is also cooled in a controlled manner.

This will increase its resistance as well as the hardness of the material, which happens precisely when it is exposed to sudden cooling, causing a molecular rearrangement in its structure. 

In addition, the tempering process generates compressive stress on the surface of the glass, where cracks can eventually occur, and thus make it difficult for them to propagate, shattering into small fragments if damaged.

In this way, tempered glass can be 5 times more resistant than common glass and is highly requested to be used in cars, furniture, doors, windows, box and several other objects that need greater security than common glass cannot offer. .
