Many people are worried that double-layered glass mugs can't hold hot water like ordinary glass mugs and are easily broken. So what is the situation? Can a double-layered glass mug really not be soaked in water? Below we will give you a brief introduction.
First, double-layered glass mugs should buy better brands, because performance and durability will be better. The sandwich air of the double-layered glass mug (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 feature of the double-layered glass mug is that the thickness of the glass layer is small. It is not easy to burst after the boiling water is poured in. However, the thickness of the glass mug is generally larger. When the interior is heated, it expands, and the outside does not have time to expand and bursts.
Pay special attention when using double-layered glass mugs in winter. Since the glass mug 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, the double-layered glass mug can be used to soak the water, but for the sake of safety, it is best to preheat it to avoid unnecessary trouble.
