Tempering Process: Tempered glass is made by uniformly heating annealed glass to a temperature of up to 700°C and immediately cooling it. The glass first goes through the furnace, carried in by rollers, where it is heated using three modes – conduction, convection and radiation. The rollers conduct the heat, while the coils help in the radiation of heat. The convection effect is brought about by hot air blowing through the nozzles, thus circulating the heat inside the furnace and making ... Toughened / Tempered glass is a safety glass that has undergone processes of controlled thermal treatment to increase its strength. It is made from annealed glass that has been heated to approximately 650⁰C and then rapidly cooled, making it significantly stronger than ordinary glass. Tempered glass is a type of safety glass that breaks into small chunks instead of sharp shards. It is used for its strength, thermal resistance, and safety in various applications, such as vehicles, buildings, household items, and touchscreen devices.
