How to distinguish tempered glass from ordinary glass?
1. Look at the glass sign
Check whether there is a tempered 3C mark on the corners of the glass. The 3C mark (the kind that cannot be scraped off) is basically tempered glass. The processing procedure of tempered glass is to first cut ordinary float glass to the required size, then grind the edges, clean it, and mark it with national compulsory certification ccc with ink. , and the ink generally cannot be scraped off after passing through high temperature. If the 3C logo on your glass can be wiped off by hand, it can basically be concluded that it is fake tempered glass.
2. See if it is slightly deformed
Check whether the glass is slightly deformed from the side, 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 shards of glass
When ordinary glass is broken, it is large flakes with sharp corners, which are easy to hurt people. After the tempered glass is broken, it is granular, the edges and corners are very dull, and it is not easy to hurt people.
