Many people are worried that double-layer glass can't hold hot water like ordinary glass, and it is easy to break. So what is the situation? Can a double-layer glass really not be boiled? Below we will give you a brief introduction.
First of all, double-layer glass should buy a better brand, because performance and durability will be better. The sandwich air of the double-layer glass (some of which is less air to be ventilated) is a poor conductor of heat, so it has a certain heat preservation function, and also has the advantage of not being hot. Another characteristic of the double-layer glass is that the thickness of the glass layer is small, and it is not easy to burst after the boiling water is poured in. However, the thickness of the glass cup is generally larger, and when the interior is heated, it expands, and when the outside is too late, it will burst.
Pay special attention when using double-layer glass in winter. Since the glass is cool, before pouring the water, pour it into a little bit, shake it, and preheat it, so that it can prevent the cup from cracking.
Therefore, double-layer glass can be used to soak water, but for the sake of safety, it is best to preheat it to avoid unnecessary trouble.
