Crystal glass is made of glass beads cast in a refractory mold. Glass beads are made of silicon dioxide and other various additives as the main raw materials. After the ingredients are mixed, they are melted and crystallized by flame. Its surface is smooth and has various formats of fine wire mesh or natural stone-like decorative patterns. It has good strength, chemical stability and atmospheric erosion resistance. Its reverse side is rough and has good adhesion to cement. It is a glass plate decorative material suitable for interior and exterior wall decoration. There are mainly the following differences between crystal glass and glass: First, the material is different. Crystal glass is a crystal of silicon dioxide, and glass is a molten mixture containing silicon dioxide. Second, the effects are different. In addition to the decorative effect, crystal glass also has piezoelectric effect and health care effects. Third, the processing technology is different: glass can be hot-cast, which saves materials and labor costs and is low, but it is easy to scratch and yellow. Crystal glass is a crystalline body and can only be processed by cold processing such as cutting and grinding. It has high hardness, is not easy to wear, and has good stability. Crystal glass is also called artificial crystal. Due to the scarcity and difficulty of natural crystal mining, it cannot meet people's needs, so artificial crystal glass was born. Due to its high transparency, it can be made into various handicrafts and is very popular in the market.
