When we were in the use of glass, will from time to time in case of blowout of the glass and we don't know why why burst. Today we had an interview with Qingdao glass products factory technical personnel, according to what he called the glass blowout is the cause of the glass is a poor conductor of heat, the cup on the cold outside, the outer wall form cold shrink rapidly, and the glass wall has not come sharp contraction, resulting in uneven heating and burst cup.

Use of glass in winter, it is important to note that only the glass is the most afraid of heat bilges cold shrink, low temperature of the glass (such as the just out of the fridge, just from the outside in the cold, don't immediately fill into the hot water, to prevent the crack. Just, when I was in the water, glass will burst, make water to the body. Really very unlucky.

This and glass manufacturing process, the average daily and toughened glass products must pass through annealing process, annealing is to eliminate internal stress existing in the glass forming process, tempered is to make the glass breaks into small granule, the avoid cuts. No after annealing, the stress in glass not effectively eliminate, very easy to burst, sometimes doesn't need outside force, would burst.

Qingdao glass products factory, therefore, to tell you again, winter use glass, pour a bit of warm water, more or less is vitreous heated evenly, and then pour into boiling water. In order to prevent the blowout of the glass, so you need to pay attention.
