Glass is divided into glass, crystal and colored glaze, which refers to crystal works made of artificial crystals of various colors (containing 24% lead dioxide) by high-temperature dewaxing and casting with ancient bronze dewaxing. Its colors are colorful and beautiful; Its quality is crystal clear and dazzling. This process needs dozens of manual operations to complete, and a slight negligence may cause failure or defects. The heavy metal is lead dioxide. But now the lower price is generally imitation glass, Shui Liu Li, resin or crystal glass instead.

Crystal cup: crystal and artificial crystal. Crystal should be very good, natural health function is very good. Anyway, I think so. Artificial crystal, artificial crystal is high lead glass, or lead crystal glass, that is, adding 24% lead oxide to ordinary glass (composed of silicon dioxide) will get artificial crystal with brightness and transparency similar to that of rock crystal. Artificial crystals with different lead oxide content have different grades, and the interior of the object is clear and the bubbles are not obvious. Nowadays, many crystal desk lamps and crystal objects are actually crystal glass, that is, artificial crystal, which is better than window glass.

Take glass as an example, the composition is the simplest, and silicon dioxide is the most important component. The lead content is relatively low.

Colored glass and crystal cup (unnatural) have different processes and similar components, so they have nothing to do with each other. A crystal cup is similar in composition to a glass. The crystal cup contains lead oxide, which can be understood as reprocessing on the glass. The specific affiliation is hard to say. Grape wine glasses can be divided into glass and crystal glass in texture, and there are obvious differences between these two kinds of wine glasses: 1, price, the price of crystal glass is more expensive than ordinary wine glasses. In particular, foreign crystal glasses, such as Italy and Austria, are all high-quality crystal cup manufacturers. 2. Purity: Due to different raw materials, the effect of wine tasting is different. Because the purity of crystal is much higher than that of ordinary glass, crystal glass can reflect the color of wine more truly and clearly when watching the color of wine. 3, the hardness of the cup wall, crystal cups are generally harder and more wear-resistant than ordinary glass. A high-quality crystal cup should have a high purity and a hard outer wall. It will make a crisp sound when it collides. After the collision, the cup will be quickly handed to your lips, and you will feel the same vibration as an electric shock. That's the "Kiss from the Crystal Cup".
