How to choose a glass that can withstand heat?

Glass is considered as a safe drinking container because of its stable chemical properties. So how to select a glass with high temperature resistance and anti-explosion is something that many people care about.

In fact, the method is very simple. Put the hot water into the glass cup, the surface of high temperature resistant glass is not hot, not high temperature resistant glass‘s surface is hot. Some glasses have a double layer design that not only insulates but also holds heat.If you buy a glass that is not resistant to high temperature, you don't have to throw it away. As long as you use it properly, it can also be used normally.

Ordinary material is not high temperature resistant glass using temperature range is between 5 to 70 degrees Celsius. Why would it suddenly rupture is suddenly encounter cold heat, causing the glass temperature difference between the parts, inflation is not uniform, when this kind of non-uniform difference is too big, the glass is easy to crack.So when using ordinary glass, before the pour boiled water, You put in a little bit of warm water, and then when the glass is warm, you add the hot water to reduce the temperature difference, and then you're fine.

High temperature resistant glasses are generally made of high borosilicate glass. The special material has a very low thermal expansion coefficient, which can not only withstand the high temperature of about 400 degrees Celsius, but also can withstand the temperature difference of about 150 degrees Celsius instantaneously. It is convenient and safe to use.

When choosing a cup, if it is a high temperature glass, there will be relevant marks on the cup, indicating the use temperature and application range. Remember not to be cheap when buying, some of the nominal heat-resistant glasses are actually ordinary materials of the glass.
