Introduction to Oven Tempered Glass

Oven tempered glass is a type of safety glass specifically designed for use in ovens and other high - temperature applications. It undergoes a special tempering process that increases its strength and resistance to thermal stress. This process involves heating the glass to a high temperature and then rapidly cooling it, which creates internal stresses that make the glass much more durable than ordinary glass.


Oven tempered glass can withstand sudden temperature changes without shattering, which is crucial in an oven environment where the temperature can fluctuate significantly during the cooking process. It also has high clarity, allowing users to observe the food being cooked inside the oven. Additionally, it is easy to clean and maintain, making it a popular choice for oven manufacturers.
