Differentiation between crystal glass bottles and common glass bottles

Crystal glass, also known as lead crystal glassware, is classified into high lead (36% PBO, 24% PBO), medium lead (18% PBO), and low lead (12-16% PBO) based on the PBO (lead oxide) content. .

There are three differences:

(1) Sound: Tap or finger the container with a finger. Crystal glassware can emit a crisp metal sound and sway in the air with a beautiful reverberation, while ordinary glassware only has a boring "click" sound.

(2) Feel: When you hold a crystal goblet, you will feel a heavy, heavy touch, while the ordinary glass only feels fluttering.

(3) Gloss: Lift a crystal glass and place it against the light. You will find that he is like a fine handicraft. It is white, crystal clear and translucent, reflecting the fascinating multicolored light, and ordinary glassware has no glossiness. There is no refraction.
