1、 Is the crystal cup made of crystal

Crystal glasses usually refer to cups or wine cups made of lead-free crystal glass and used to hold water. With the development of modern technology and craftsmanship, crystal glass has gradually become widely used as tea cups, wine cups, etc., and is highly favored by fashion professionals in the new era. Another type is lead-free crystal wine glasses, which are more popular among consumers due to their higher transparency and brightness.

A crystal cup is a type of glass cup, whose main component is silicon dioxide, and elements such as lead, barium, zinc, and titanium are added to it. Therefore, with high transparency and refractive index, this glass cup has a smooth and crystal clear appearance, hence it is called crystal glass. If lead is added during production, it is called lead crystal. Adding elements such as steel, zinc, and iron is called lead-free crystal.

2、 How much temperature can a crystal cup withstand

The temperature that a crystal cup can withstand is 800-1400 degrees Celsius, and the temperature it can withstand varies depending on its composition. Crystal cups are more durable than regular glass cups

The temperature that ordinary household heating products can reach cannot melt or even soften the crystal cup. It should be noted that although crystal cups can withstand high temperatures, they generally have poor resistance to extreme cold and heat. Moreover, crystal cups are prone to cracking when subjected to uneven heating. For example, if a thick glass is suddenly filled with hot water in a cold environment, the glass will crack, which is caused by the stress generated by thermal expansion and contraction. In theory, the thinner the wall of a crystal cup, the less likely it is to break under uneven heating and cooling conditions. Thick cup walls are actually prone to cracking.
