What points will I teach you to distinguish between tempered glass and ordinary glass

1. Wearing a flat mirror in the sunlight, tempered glass is floral, glass is not.

2. Wearing polarized sunglasses allows you to see colorful patterns, which should not be visible without tempered glass.

3. Turning angle, in fact, also depends on whether there are pressure marks on the surface of the glass. You will see irregular deformation of the entire glass surface.

4. Looking at the side, when the glass is tempered, it will soften, and the flatness will deteriorate due to the roller conveyor. When facing the surface, the empty space in the center is an ellipse, which is very noticeable.

5. Tempered labels are printed on glass using high-temperature ink through screen printing. During the process of glass tempering, the high-temperature ink blends with the surface of the glass. Therefore, the tempered label on the glass cannot be removed without using hydrofluoric acid scrubbing (even if hydrofluoric acid is used, it will leave significant marks). Therefore, a simple and direct way to check whether the glass has been tempered is to mark it with a tempered glass label.

6. Be able to use sharp objects to exert force on the edge of the glass (preferably in areas that will not be visible in future installations). If scratches occur easily, it indicates that the glass has not been tempered. If the surface of the glass is hard and difficult to scratch, it indicates that the glass has been tempered.

7. Breaking a piece of tempered glass, the fragments will break into uniform small particles and not spread throughout the glass blade.

8. The flatness of tempered glass is worse than that of ordinary glass. A simple method is to place two pieces of glass facing each other vertically and closely together, investigate the two long sides of the two adjacent pieces of glass, and see if there is a significant gap between the long sides of the two pieces of glass. If there is a gap, it should be in a certain arc shape. If so, it should be tempered glass.
