1. Look at the glass logo, check if there is a tempered 3C logo at the corners of the glass, and the ones with a 3c logo that cannot be scraped off are basically tempered glass.

The processing procedure for tempered glass is to first cut ordinary float glass to the required size, then grind the edges, clean, and mark with ink the national mandatory certification CCC mark. After the finished product is fired in the tempering furnace, the glass cannot be cut or processed.

And ink generally cannot be scraped off after passing through high temperatures. If the 3C mark on the glass can be wiped off by hand, it can basically be concluded that it is fake tempered glass.

2. From the side, check if there is slight deformation of the glass, as it can only be seen from the side of the glass after being fired at high temperature. The front side is generally not easy to see.

       3. Looking at the fragments of glass, ordinary glass is broken into large pieces with sharp corners that are prone to injury. After the tempered glass is broken, it is granular, with blunt edges and corners, which are not easy to hurt people.

       Maintenance methods for tempered glass:

       Try not to forcefully collide with tempered glass. During daily cleaning, you can use a damp towel or newspaper to wipe gently. If there are stubborn stains, you can dip them in beer or warm vinegar to wipe, which can easily remove the stains. In addition, glass cleaning agents can also be used, and be careful not to use cleaning agents with strong acidity and alkalinity.

Tempered glass surface is easy to frost in winter, so it can be dipped in strong brine or Baijiu to wipe, with good effect.
