principle

 

The purpose is to eliminate permanent stress and structural imbalance in glass products. Glass is a poor heat conductor. After the product is formed, a temperature difference occurs between the surface layer and the inner layer during the cooling process. When the surface layer is solidified and the inner layer is viscous, the temperature difference exists but the stress relaxation does not exist. This temperature difference is when the surface layer is cooled to room temperature. , the inner layer continues to cool down and shrink, and is hindered by the surface layer to generate tensile stress, and at the same time, the surface layer generates compressive stress, which exists permanently
