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.
2. In addition to distinguishing by the logo, we can also look at the color of the two glasses. The lead-free glass is more intuitive than the lead-containing glass, and can better show the refraction, like crystal wine glasses, crystal lamps, etc. These handicrafts It is made of leaded glass.
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.
