- Apr 05, 2020-

The crystal cup is also a glass. The most important component is silicon dioxide, but lead, barium, zinc, titanium and other substances are introduced. Because this kind of glass has high transparency and refractive index, its appearance is smooth and clear, so it is called crystal glass.

If lead is introduced, it is lead crystal.

The introduction of barium, zinc, titanium and other substances is lead-free crystal.
