The advantages of crystal glass cups over ordinary glass cups:

1. The raw material for crystal glassware is pure high-quality potassium carbonate extracted from plant ash, which is completely free of heavy metals, making the vessels safer and more reliable.
2. The hardness of crystal glass is 7, while that of ordinary glass is 5, so crystal glass is more resilient, meaning it has better impact resistance.
3. Crystal glasses have better refractive properties than traditional glass cups. When you hold a crystal glass and rotate it under light, you will find that it looks like a piece of exquisite art, with its pure white and transparent appearance, refracting the enchanting colors of the rainbow. This is because crystal can absorb luster, even ultraviolet rays, whereas ordinary glass cups do not have luster or refractive properties.
4. Beyond the metallic sound produced by ordinary glass cups, the sound of crystal glass cups is more pleasing to the ear, and it resonates with beautiful overtones, earning the reputation of being "music";
