Glass is an amorphous inorganic non-metallic material, is generally prepared by using various inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash and the like) as main raw materials and adding a small amount of auxiliary raw materials, and is widely applied to wind insulation and light transmission of buildings. In order to meet various requirements in production and life, people carry out deep processing treatment on common plate glass, such as laminated glass. The laminated glass is a composite glass product which is formed by two or more pieces of glass, wherein one or more layers of organic polymer intermediate films are sandwiched between the two or more pieces of glass, and the glass and the intermediate films are permanently bonded into a whole after special high-temperature prepressing (or vacuumizing) and high-temperature high-pressure processing. Even if the laminated glass is broken, fragments can be stuck on the film, the surface of the broken glass still keeps clean and smooth, the fragments are effectively prevented from being stabbed and penetrating the falling event, and the personal safety is ensured.

Besides high safety and good sound insulation effect, the laminated glass can utilize one or more layers of sandwiched membranes and films and realize decorative effect by using the colors and patterns of the sandwiched membranes as decorative surfaces. However, the decorative effect of the laminated glass is single only by the color and the pattern of the sandwiched film, so that a new decorative form of mixing the carved metal layer in the laminated glass appears, specifically, required patterns are processed (etched, carved or in other ways) on the metal layer, and the pigment is coated on the metal layer, so that the decorative effect of the laminated glass is fully improved.
