How to identify lead-free glass? 1. Look at the label: lead-free glass generally contains potassium, and most of them are high-end handicrafts with labels on the outer packaging; while leaded glass contains lead, that is, the crystal glassware commonly seen in some supermarkets and street stalls, the lead oxide content can reach 24%. 2. Look at the color: Lead-free glass has better refractive index than traditional lead-containing crystal glass, and more perfectly displays the refractive index of metallic glass; for example, some ornaments of various shapes, crystal wine glasses, crystal lamps, etc. are made of lead-containing glass. 3. Look at the heat resistance: Glass cups can generally withstand very high temperatures, but generally have poor resistance to extreme cold and heat. Lead-free crystal glass has a high expansion coefficient and is less resistant to extreme heat and cold. If you use boiling water to make tea in a particularly cold lead-free glass, it is prone to bursting. 4. Weigh the weight: Leaded crystal glass products are slightly heavier than lead-free crystal glass products. 5. Listen to the sound: The sound of lead-free glass is more pleasant than the metallic sound of lead-containing crystal glass, and it is known as the "musical" cup. 6. Look at toughness: lead-free glass is more resilient and impact-resistant than lead-containing crystal glass.
