The crystal glassware, also known as the lead crystal glassware, is divided into high lead (36%PBO and 24% PBO), medium lead (18% PBO) and low lead (12-16% PBO) according to the PBO (lead oxide) content.
Three Major Differences:
1. Sound: gently knock or finger a vessel, the crystal glassware will make a clear sound and transmit a graceful aftersound in air, but the common glassware will only make a boring “kaka” sound.
2. Handfeel: when gently grasping a crystal high-heel bar cup, you will have a kind of heavy handfeel, but for the common glass, you will only have a kind of light handfeel.
3. Glossiness: when raising a crystal cup up to the light, you will find it’s just like a delicate handicraft which is pure white, glittering and translucent, and can refract charming colorful lights, but the common glassware is low in glossiness and doesn’t refract lights.
