What is a good material for a glass tea cup?

Ordinary glass teacups are easy to be heated unevenly, resulting in different temperatures of various parts. Due to the principle of thermal expansion and cold contraction, when the heating unevenness and difference are too large, the glass is easy to break. At the same time, the heat resistance of ordinary glass is not high, and the glass is easy to break when the temperature is too high.

The high borosilicate glass teacup is made by firing at high temperature. It can adapt to high temperature and low temperature. It can hold 100 ℃ hot water without breaking. It has no common thermal expansion and cold contraction of ordinary objects. Tea, acid drinks and other liquids are also free from peculiar smell and cross smell.

Another point that needs special explanation is that high borosilicate is only a special glass material with high chemical stability. As for the concept of silicon dissolution, it does not exist at all. Moreover, the high borosilicate glass teacup is easy to clean and meets the safety standard.

When buying glass, you should look for lead-free glass. It doesn't matter what kind of glass it is, but it must be lead-free. Finally, the bottom of the glass is thicker and more durable.
