The material of the glass is relatively easy to break, and it is a common phenomenon to break and melt. The broken glass of the glass is easy to burn people, and it can not be used in the later stage. The double glass is also difficult to escape. So, how can we prevent it? Is the inner layer broken and broken?
1. To purchase a product with better quality, it has the function of preventing explosion.
2, buy a double-layer glass, buy it back and put it in water to heat the boil, after which it can prevent cracking.
3, do not immediately fill the hot water when using in winter, you can use a small amount of water temperature before use, to prevent the temperature difference is too large and cause bursting. Or dip the cup in warm water, then rinse the water, or pour a small amount of boiling water, shake the glass, make the inner wall of the glass evenly heated, and then fill the water, so that it is not easy to burst.
As can be seen from the above, we need to ensure the quality of the double-layer glass inside the cracking and breaking, and then use other techniques. Generally, the glass is burnt because of the uneven expansion of the glass, and then the pressure difference with the external environment is caused. If the double-layer glass is broken without hitting the inner layer with a hard object, it is a quality problem.
