The glass is divided into double-layer glass and single-layer glass. The production process is different. The double-layer mainly meets the needs of advertising cups. The company’s logo can be printed on the inner layer for promotional gifts or gifts, etc., and the thermal insulation effect is better. Outstanding. Lead crystal glass, commonly known as crystal glass, is generally used to make goblets. It is characterized by good refraction, good hand feel, and a crisp and pleasant sound when tapped. However, some consumers questioned its safety, believing that using this cup to hold acidic beverages would lead to the precipitation of lead, which is harmful to health. In fact, this kind of worry is unnecessary, because the country has strict regulations on the amount of lead precipitation in such products, and has set experimental conditions, which cannot be replicated in daily life. However, experts still advise against long-term storage of acidic liquids in lead crystal glasses. Tempered glass, this material is made of ordinary glass through physical tempering.
Glass is an amorphous inorganic non-metallic material, generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw material, and a small amount of auxiliary raw materials are added. of. Its main components are silica and other oxides. The main component of glass is silica, which is hard and brittle, and is a colorless and transparent material. Various components can be added to make brown glass, light ink glass, cobalt blue glass, etc. The crystal cup is also a kind of glass cup, and the main component is also silicon dioxide, but lead, barium, zinc, titanium and other substances are introduced into it. Because this glass has high transparency and refractive index, its appearance is smooth and crystal clear, so it is called crystal glass. If lead is introduced, it is lead crystal. The introduction of barium, zinc, titanium and other substances is lead-free crystal. .
