How Should Consumers Choose Tempered Glass?

Mar. 21, 2019

Tempered glass is tempered by heat treatment, and thus has a stress pattern during heat treatment. Therefore, the stress pattern provides us with a strong certificate for distinguishing the quality of tempered glass! However, because the stress pattern is invisible to the naked eye, it is usually judged by the external light. As a company that producesGlass Impact Testing Device, we teach you how to identify tempered glass without Glass Impact Testing Device.

Light reflection discrimination using the sky outdoors or indoors using windows: Look at the light reflected from the glass or the window, and slowly change the angle of observation. In the case of tempered glass, it is possible to see a column of blue-grey regular, dark intermediate, shallow and fuzzy circles, or elliptical, or elongated patterns on the surface of the glass. In addition, we can also observe the quality defects such as bubbles, inclusions, scratches, lines and fog spots in the glass. This is a strong evidence for us to judge the quality of tempered glass.

Glass Impact Testing Device

1. Check the product factory certificate, pay attention to the CCC mark and number, date of manufacture, specifications, technical conditions, and company name.

2. Wear polarized sunglasses to view the glass, and the tempered glass should show colored streaks.

3. The flatness of the tempered glass will be worse than that of ordinary glass, and the surface of the tempered glass will be touched by hand to have a feeling of unevenness. Observing the longer side of the tempered glass, there will be a certain degree of curvature. Putting the two larger tempered glass together, the curvature will be more obvious.

4. Tap with your hand and listen to the sound. The tempered glass sounds crisper and has the feeling of striking the steel plate. Normal glass does not.

5. Look at the glass under the light side, and the tempered glass will have blue spots.

6. One thing consumers should bear in mind is to guard against the decoration company or the decoration team, and to pretend to be tempered glass without tempered glass. The simplest test method is to touch the edge of the glass. The edge of the ordinary glass is easy to cut, and the edge of the tempered glass is smoother and will not cut the hand.
