How to distinguish between tempered glass and ordinary glass


See if there is a toughened 3C mark on the corners of the glass, and those marked with 3c (the kind that cannot be scraped off) are basically toughened glass. The processing procedure of tempered glass is to cut ordinary float glass into the required size, then edge grinding, cleaning and marking with ink for national compulsory certification ccc. The glass after being fired in the tempering furnace cannot be cut or processed. The ink in the high temperature after the general situation is not scraped off. (If the 3C logo on your glass can be wiped off by hand, it can be concluded that it is fake tempered glass)

2. See if it is slightly deformed
From the side to see whether the glass is slightly deformed, because after the glass is fired at high temperature, there will be slight deformation, which can only be seen from the side of the glass, and the front is generally not easy to see.
3. Look at the pieces of glass
After ordinary glass is broken, it is large and has sharp corners, which is easy to hurt people. After the broken glass is granular, the corners are very blunt, not easy to hurt.
