Its color clouds of color, the United States round the United States, its quality crystal clear, dazzling. This process takes several decades of manual manipulation to complete, a slight negligence can cause failures or defects. Heavy metals are lead dioxide. But now the lower price is generally imitation glass, is water glass, is resin, or crystal glass substitute made.

Crystal Cup: divided natural crystals and man-made crystals. Natural crystal, should be very good, natural health function is very good, anyway, I think so. Man-made crystals, which are high-lead glass, or lead-crystalline glass, known as lead oxide by adding 24% of PB in Ordinary glass (constituent silicon dioxide), will get the brightness and transparency of man-made crystals similar to natural crystals.
