Toughened Glass is made from annealed glass via a thermal tempering process. The Toughened Glass is placed onto a roller table, taking it through a furnace that heats it above its annealing point of about 720 ^oC. The Toughened Glass is then rapidly cooled with forced air drafts while the inner portion remains free to flow for a short time. Toughened Glass is used when strength, thermal resistance and safety are important considerations. The most commonly encountered Toughened Glass is that glass, which is used for side and rear windows in automobiles. Toughened Glass is also used in buildings for unframed assemblies (such as frameless doors), structurally loaded applications, and any other application that would become dangerous in the event of human impact.
