Disadvantages Of Tempered Glass

1. Tempered glass cannot be cut or processed. The glass can only be processed to the required shape before tempering, and then tempered.
2. Although tempered glass is stronger than ordinary glass, tempered glass has the possibility of self-explosion (self-rupture), while ordinary glass does not have the possibility of self-explosion.
3. The surface of tempered glass will be uneven (wind spots) and slightly thinner. The reason for the thinning is that after the glass is softened by hot melt, it is quickly cooled by strong wind, which makes the crystal gap inside the glass smaller and the pressure larger. Therefore, the glass is thinner after tempering than before. Generally, 4~6mm glass becomes 0.2~0.8mm thinner after tempering, and 8~20mm glass becomes 0.9~1.8mm thinner after tempering. The specific degree depends on the equipment, which is why tempered glass cannot be used as a mirror.
4. Flat glass for construction after passing through the tempering furnace (physical tempering) will generally be deformed, and the degree of deformation is determined by the equipment and technicians' workmanship. To a certain extent, the decorative effect is affected (except for special needs).
