The glass surface is smooth and easy to clean. Bacteria and dirt are not easy to grow on the wall of the glass. The most commonly used borosilicate glass water cup does not contain organic chemicals in the process of firing. When making tea or drinking coffee and other drinks with a glass, you do not need to worry about chemicals entering the human body, so drinking water with a glass is relatively healthy and safe. Glasses are mainly divided into ordinary glasses, high borosilicate glasses and crystal glasses according to material. The sodium-calcium glass is mainly composed of silicon dioxide, sodium oxide and calcium oxide. Although the most common glass water cup in life can hold hot water, its thermal conductivity is poor, and it is easy to crack in extremely cold and hot conditions. Therefore, we must have experienced or heard of glass cracking in general. When using this kind of glass to fill hot water, you can pour a bit of rinse glass to preheat it. There is no problem with daily use.
High borosilicate glass is a kind of glass with sodium oxide (Na2O), boron oxide (B2O3) and silicon dioxide (SIO2) as the basic components. The high borosilicate glass is safe, stable, non-toxic, and has a very low coefficient of thermal expansion, which is only about one third of that of ordinary glass. Therefore, it can withstand sudden temperature difference. For example, the glass will not break when taken out of the refrigerator to pour hot water. It is a good glass cup material commonly used in life.
