At 4 o'clock in the morning, the glass at home blew itself up for no reason. What happened?

The glass itself has the defect of self-explosion, and the national regulations allow a probability of 0.3%. This self-explosion is due to the quality problem of the glass itself, which leads to the self-explosion of tempered glass.

Due to the manufacturing process, ordinary glass can withstand the temperature change of about 200℃ without cracking. If the process is not good, it will easily lead to glass breaking at low temperature. The weakest part of tempered glass is the four corners, followed by the distance from the glass edge10 mm. If there is a collision, the glass will break easily.

Matters needing attention in the use of glass

Don't hit the glass surface hard at ordinary times. To prevent scratches on the glass surface, do not rub with hard objects to avoid collision.

Wipe with a wet towel or newspaper during daily cleaning. If there is any stain, wipe it with a towel dipped in beer or warm vinegar. In addition, you can also use the glass cleaning agent currently sold in the market to avoid cleaning with a solution with strong acidity and alkalinity. The surface of glass is easy to frost in winter, so it can be wiped with cloth dipped in concentrated salt water or white wine, and the effect is very good.
