Tempering Glass
 Tempering the glass is a process of thermal operation that is performed on house glasses. That process may be performed on colored decorative glasses, reflective, printed or glazed ones, too.
The Process of Tempering Glass
Thermal operation: thermal operation is the integrated heating of the frame glass until the softening temperature of the glass (above 700 degree centigrade).The heated glass is quickly cooled by blowing the cold air on both surfaces of the glass. In this process the glass is heated up to softening point which is above 700 degree centigrade, then the cold air is blown quickly on both surfaces. In cooling stage of the glass the outer layers are cooled faster than the inner ones which makes the glass more strong.
While the glass is being cooled the surfaces are cooled faster than the center and this makes permanent tensions and consequently more strength.
Virtues of Using Tempered Glass
Comparing the raw glasses with the same thickness, the tempered glass has more resistance against breaking in a way that its mechanical resistance becomes five times more than the raw glasses. In a case of breaking down the tempered glass turns into small pieces with polished edges that do not cut. This virtue lowers the risk of damage.
Utilizing Items
The tempered glass is usually applied in places that strength, resistance against temperature and safety is concerned. Generally the tempered glass is used in automobile industry for preventing the glasses to break down to small pieces. When parameters such as mechanical strength and safety are concerned the tempered glass is at the center of attention. In automobile industry for side and rear windows the tempered glass is used but for the windshield the laminate glass is used because of their more resistance and not scattering when crack up. In housing industry, the tempered glass is used for the frameless items like the entrance gates and doors or everywhere that there is the risk of damage.
The tempered glass is not cut-able or formable, so works like cutting or perforation and so on should be accomplished before tempering the glass.
