Annealing of glass products is to eliminate or weaken the residual stress and optical inhomogeneity in the products to the greatest extent, and to stabilize the internal structure of
the glass. For glass products that have not been annealed, the internal structure has not been in a stable state, such as the change in glass density after annealing.
Annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate
speed. The purpose is to reduce the hardness, improve the machinability; reduce the residual stress, stabilize the size, and reduce the tendency of deformation and cracking.
Refine the grains, adjust the organization, and eliminate the organization defects. To be precise, annealing is a heat treatment process for materials, including metallic materials and
non-metallic materials. Moreover, the annealing purpose of the new material is similar to that of the traditional metal annealing.
