What are the materials of the glass

1. Soda-lime glass water cup is also the most common glass water cup in our lives. Its important components are silicon dioxide, sodium oxide, and calcium oxide. This kind of water cup is made by mechanism and manual blowing, low price, and daily necessities. If the soda lime glassware is used for drinking hot drinks, it usually needs to be tempered when leaving the factory, otherwise the cup will crack if the temperature difference is too large.

2. High borosilicate glass water cup, this kind of glass is named because of the high content of boron oxide. The tea sets and teapots commonly used for making tea can withstand large temperature changes without breaking. But this kind of glass looks thin, light weight, and feels bad.

3. Crystal glass water cup, this kind of glass is a high-end product in glass, because it contains many metal elements, its refractive index and transparency are very close to natural crystal, so it is called crystal glass. There are two types of crystal glass, lead crystal glass and lead-free crystal glass. Lead crystal glass is not recommended for consumption, especially when you drink acidic beverages from drinking glasses. Lead will dissolve into the acidic liquid, and long-term consumption will cause lead poisoning. Lead-free crystals do not contain lead elements and are harmless to the body. When buying a glass, you must look for lead-free glass. As for the kind of glass, it is not important, but it must be lead-free. In the end, the bottom of the cup is thicker and more durable.
