Method of identifying safety glass

[China Glass Network] 1. The more important and safer method is to see if there is a 3C certification mark on the safety glass. Because according to regulations, the 3C certification mark must be on the safety glass.

2. By listening, that is to say, hitting the glass by hand, if the glass makes a crisp sound, the glass is tempered glass, and vice versa is ordinary glass.

3. When a polarizing plate is used, it is a tempered glass that can see a color strip on the side of the glass through the polarizing plate, and a black and white spot can be seen in the surface layer of the glass. Polarizers can be found in camera lenses or glasses, and attention is paid to the adjustment of the light source during viewing, which makes it easier to observe.
