glass tempering furnace

Tempered glass is a type of safety glass that has been tempered in a glass tempering furnace to increase its strength and impact resistance. This process involves heating the glass to a high temperature (usually around 600-700°C) and then rapidly cooling it through a quenching process. However, in some cases, tempered glass may crack or even break […]
