The glass water bottle 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 glass water bottle and glass water bottle with lead crystal glass water bottle. So how do we identify lead-free glass water bottles?
The method is actually very simple. We can distinguish between leaded glass water bottle and lead-free glass water bottle in terms of weight, logo, color and heat resistance.
Look at the logo: lead-free glass water bottles generally contain potassium, mostly high-end crafts and are marked on the outer packaging; while lead-containing glass water bottles contain lead, that is, the common crystal glass water bottles are commonly found in some supermarkets and stalls, the content of lead oxide Up to 24%.
Look at the color: lead-free glass water bottle has better refractive index than traditional lead-containing crystal glass water bottle, and more perfectly shows the refractive performance of metal glass water bottle; such as some kinds of ornaments, crystal wine glass water bottles, crystal lamps, etc. Made of lead glass water bottle.
Look at heat resistance: glass water bottle water bottles can generally withstand very high temperatures, but generally have poor cold and heat resistance. Lead-free crystal glass water bottle is a kind of 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 glass water bottle, it will easily burst.
Slight weight: Leaded crystal glass water bottle products are slightly thicker than lead-free crystal glass water bottle products.
Listen to the sound: Beyond the metallic sound of leaded crystal glass water bottle, the sound of lead-free glass water bottle is more pleasant and beautiful, and has the reputation of "music" cup.
Look at toughness: Lead-free glass water bottle is more tough than lead-containing crystal glass water bottle, that is, impact resistance.
