Glass wine bottle is a historical packaging container, glass bottle manufacturers in the production of wine bottles, will put some lead inside, which can improve the quality of glass bottles, but lead is a harmful substance to the human body, so how do we detect whether glass bottles contain lead?
1. Listen to the sound. Glass bottles containing lead emit a metallic sound, and glass bottles without lead emit a pleasant sound.
2. Look at the color. Lead-free glass wine bottles have better refractive properties than glass bottles containing lead, such as some ornaments of various shapes, crystal wine glasses, etc. are made of leaded glass.
3. Weigh the weight. Leaded glass products are slightly thicker than lead-free glass products.
4. Look at toughness. Compared with lead-free glasses, lead-free glasses are more tough and impact-resistant.
