Another name of this glass is "tempered glass". The heat treatment process of solidified tempered glass also makes it heat resistant and makes it ideal for many DIY projects.Because of the way tempered glass is heat-treated, it breaks into small, safe pieces rather than large shards. This is called "dicing" and makes tempered glass safer than standard annealed glass. For this reason, tempered glass is most often used where standard glass could pose a danger.We have perfected the process for hand-crafting your tempered glass pieces. The first thing you should know is that your tempered glass is cut to size. In fact, we cut, polish, and finish your glass to your specificationsbeforewe temper it. Cutting tempered glass after tempering is not recommended. After your glass is cut, we put it in our own tempering ovens, so we know how your glass is treated from start to finish. After your glass comes out of our tempering ovens, we finish it with a high-pressure cooling treatment to complete the process. Federal regulations state that tempered glass must have a surface compression of 10,000 psi or more. It usually breaks at around 24,000 psi.Edge processingThickness3-19mmSize avaliableLargest 4200x2440mmSmallest 250x150mmColor avaliableClear, dark/lake/ocean blue,dark/f/h green,bronze,grey, etc.Glass types avaliableFloat glass, on-line low-e glass, off-line low-e glass,sunny control glass, acid atteched glass,etc.Processing Technology Before Tempering1.Edge processing method: polished edges, beveled edges, chamfered edges or grinding edges2.Drilling holes3.Cut out
