Good glasses electroplating after three processes, the first is in the glasses or pure raw materials, plating a layer of an adhesion layer, used to attach the plating color layer. The second is the electroplating color layer. The third one is that after the electroplating color layer, another layer of electroplating protection is transparent.

Although crystals are expensive, they have high ultraviolet and infrared transmittance.
