Fully tempering process increases the glass strength and the resistant against thermal stresses. Ardıç Glass tempering process includes the heating and cooling stages on horizontal line caused to gain a compression strength on external surface and indirect tensile strength in the middle of the tempered glass that is approxiamately five times more resistant than annealed glass is suitable to use as a safety glass because when it is broken, it fall into small pieces at size of a
dice thus reduces the risk of injuries.
Heat-treatment doesn’t change the volume, chemical structure, colour or clarity of glass products. Clear float, body-tinted float, laminated glasses (before laminating process) and coated glasses, can be heat-treated. After the heat treatment, they can not be cut, drilled or made any edge, surface process.
Some of the distortions such as ‘tempering marks’, ’hunch’ and ’concavity’ among tolerances, which can only be noticed from certain angles and under certain conditions of light, are inevitable results of heat-treatment. The tempering marks reduced to a minimum with the application of very sensitive heat regime during the tempering aren’t classified as an error on its own.
Against the posibility of spontaneous breakage rarely occured caused by microscopic particles as a result of some manufacturing methods, thermally toughened glass can be exposed to heat-soaking test as a pre-elimination if desired.
Thermally toughened glasses are manufactured suitable to soda, calcium, silicate safety glass used in glass structures as in TS EN 12150 Standard.
