What are the materials used to make glass cups?

Material division:

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

2. High borosilicate glass water cup, which is named after the high content of boron oxide. Commonly used tea sets and teapots for making tea can withstand large temperature changes without breaking. But this kind of glass looks thin and light, 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 refraction and transparency are very close to natural crystal, so it is called crystal glass. There are two kinds of crystal glass, lead crystal glass and lead-free crystal glass. Lead crystal glass is not recommended to be eaten, especially if you drink acidic beverages from water glasses, lead will dissolve into acidic liquids, and long-term use will cause lead poisoning. Lead-free crystal is lead-free and harmless to the human body.

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