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.
