If you are looking for strong and heat-resistant glass, toughened glass is the right one. While manufacturing toughened glass, its inner layer undergoes a greater contraction. This adds to the strength of the glass. Toughened glass is prepared from annealed glass through the process of thermal tempering. Annealed glass is heated up to 720 °C and then cooled rapidly to manufacture toughened glass. Surface of toughened glass is less hard compared to the annealed glass. It makes the glass scratch susceptible. However, to counter this problem glass manufactures are now manufacturing laminated glass. In laminated glass, there coating over the surface of toughened glass.
Two types of toughened glass are available in market. They are heat strengthened toughened glass and fully tempered toughened glass. While heat strengthened glass is synonymous with strength and durability, the speciality of fully tempered glass is its heat withstanding capacity.
Toughened glass needs to be cut to the exact size before toughening as cutting is not possible once toughened. Hence, manufacturers finish all the polishing and drilling before toughening. As these are more vulnerable to scratch, using it at window is not a viable option.
The advent of Internet has made the availability of toughened glass easier. With few clicks on computer you can collate scores of relevant information related to toughened glass. Here, you also have the opportunity compare price and quality at multiple vendors from the comfort of home. Online clearance sale on toughened glass enables you to have better deal attractive discounts.
