Ordinary annealed glass, tempered glass is first cut into the required size, then heated to near a softening point of about 700 degrees 10mm tempered glass, and then rapidly cooled to obtain a homogeneous glass (usually 5-6MM heated at 700 degree heat 240 or so seconds, cooling about 150 seconds .8-10MM glass is heated at about 500 seconds 700-degree heat, cool for about 300 seconds. In short 8mm tempered glass, depending on the thickness of the glass, select the heating cooling time is different). After treatment of steel glass surface to form a uniform compressive stress, and the internal tensile stress is formed, so that the flexural and impact strength of glass can be improved, and its strength is about four times more than ordinary annealed glass. Has been handled well tempered steel flat glass, can no longer be any cutting, grinding and other processing or subject to damage, otherwise it will cause damage even stress balance and "destroyed." The middle part is the most solid glass, corners and edges are the weakest. The best way is to use safety glass hammer edges and corners, especially the middle of the top edge of the glass where once the glass has cracked, it is easy to block smashed.
