<p>The <a href="https://www.fr-promotion.com/" target="_blank">glass</a> <a href="https://www.fr-promotion.com/" target="_blank">water</a><a href="https://www.fr-promotion.com/" target="_blank"> bottle</a> is divided into ordinary glass water bottle and crystal glass water bottle, and the crystal glass water bottle is divided into two types: lead-free crystal&nbsp;glass water bottle and&nbsp;glass water bottle with lead crystal glass water bottle. So how do we identify lead-free<a href="https://www.fr-promotion.com/" rel="noopener noreferrer" target="_blank">&nbsp;glass water bottles</a>?</p><p><br></p><p><br></p><p>The method is actually very simple. We can distinguish between leaded&nbsp;glass water bottle and lead-free&nbsp;glass water bottle in terms of weight, logo, color and heat resistance.</p><p>Look at the logo: lead-free&nbsp;glass water bottles generally contain potassium, mostly high-end crafts and are marked on the outer packaging; while lead-containing&nbsp;glass water bottles contain lead, that is, the common crystal&nbsp;glass water bottles are commonly found in some supermarkets and stalls, the content of lead oxide Up to 24%.</p><p>Look at the color: lead-free&nbsp;glass water bottle has better refractive index than traditional lead-containing crystal&nbsp;glass water bottle, and more perfectly shows the refractive performance of metal&nbsp;<a href="https://www.fr-promotion.com/" rel="noopener noreferrer" target="_blank">glass water bottle</a>; such as some kinds of ornaments, crystal wine&nbsp;glass water bottles, crystal lamps, etc. Made of lead&nbsp;glass water bottle.</p><p>Look at heat resistance:&nbsp;glass water bottle water bottles can generally withstand very high temperatures, but generally have poor cold and heat resistance. Lead-free crystal&nbsp;glass water bottle is a kind of&nbsp;glass water bottle with a high expansion coefficient, and its resistance to extreme cold and heat is even worse. If you make tea with boiling water in a particularly cold lead-free&nbsp;glass water bottle, it will easily burst.</p><p>Slight weight: Leaded crystal&nbsp;<a href="https://www.fr-promotion.com/" rel="noopener noreferrer" target="_blank">glass water bottle</a> products are slightly thicker than lead-free crystal&nbsp;glass water bottle products.</p><p>Listen to the sound: Beyond the metallic sound of leaded crystal&nbsp;glass water bottle, the sound of lead-free&nbsp;glass water bottle is more pleasant and beautiful, and has the reputation of "music" cup.</p><p>Look at toughness: Lead-free&nbsp;glass water bottle is more tough than lead-containing crystal&nbsp;glass water bottle, that is, impact resistance.</p>
