Information
As the saying goes, you need to drink eight glasses of water a day, which also fully shows that water is the source of life and its importance is self-evident. Everyone needs to drink water every day to supplement water and maintain the normal metabolism of the body. The water cup, as the carrier of water, is also a very important existence. Nowadays, most of the water glasses on the market are mainly glasses with a wide variety. Therefore, how to select a high-temperature resistant and anti cracking glass is a matter of concern to many people.
In fact, the method is very simple. After loading hot water, the surface of high-temperature resistant glass is not hot, and the surface of non high-temperature resistant glass is hot after loading hot water. Some glasses adopt double-layer design, which can not only insulate but also keep warm.
If you buy a glass that is not resistant to high temperature at home, you don't have to throw it away. It can be used normally as long as it is handled properly. The use temperature range of ordinary glass which is not resistant to high temperature is "- 5 ℃ to 70 ℃. The reason why it will break suddenly is that it will suddenly encounter cold and heat, resulting in large temperature difference and uneven expansion between various parts of the glass. When this uneven difference is too large, the glass is easy to burst. Therefore, when using ordinary glass, before pouring boiling water, Put a little warm water first, and then add boiled water after the cup is warm to reduce the temperature difference borne by the glass, so there is no problem.
High temperature resistant glass generally uses Gaopeng silicon glass. The special material has a very low coefficient of thermal expansion. It can not only bear the high temperature of about 400 degrees Celsius, but also bear the instantaneous temperature difference of about 150 degrees Celsius. It is easy to use.
When purchasing a cup, if it is a high-temperature resistant glass, there will be relevant marks on the cup, indicating the use temperature and scope of application. Remember not to be greedy when buying. Some nominal heat-resistant glasses are actually ordinary glasses.
