The difference between leaded glass and lead-free glass
1. The first one, we can judge by the logo. Lead glass, which is generally lead, is used in high-end handicrafts, and there must be some corresponding logos on the outer packaging. Lead-containing glass, because the lead-containing lead oxide content reaches 24%, is generally used in crystal glassware.

3. We can also distinguish by the heat resistance of the two glasses. Lead-free glass is relatively poor in heat resistance.
4. We can also distinguish by weight. Products made of leaded glass are slightly heavier than those made of lead-free glass.
5. It can also be judged by sound. Compared with lead-containing glass, lead-free glass will emit a crisp sound after being tapped, but the sound of lead-containing glass will be heavier.
