How to distinguish crystal glassware from other glassware

Post Time:Dec 04,2008Classify:Industry NewsView:441

Crystal glass, namely lead crystal glassware, is divided into three classes according to the PBO content, that is high-lead (36% PBO or 24% PBO), medium-lead (18% PBO) and low-lead (12-16% PBO) crystal. There are three ways to distinguish it from ordinary glassware:

1. Sound: lightly knocking the glassware. Crystal glassware is sounded like metal and with a lingering sound, while other glassware gives off the “KAKA” sound.

2. Touch: lightly holding a crystal goblet, you will feel a sense of massiveness, but only a feather-like sense for other glassware.

3. Glossiness: crystal cup looks like an exquisite craft when put under light, pure white, sparkling and transparent. It reflects attractive and colorful lights. However, other glassware is lusterless and not reflective.
