Glass reflection imaging of surface processing of electroless silver plating and vacuum evaporation method, is the most commonly used method of electroless silver plating. This method is in the silver nitrate is soluble in water, and ammonia and sodium hydroxide, ammonia hydroxide solution and dilute to silver salt, made of silver plating liquid. To invert sugar, sodium potassium tartrate or formaldehyde solution for reducing solution. Glass cutting, edging (by polishing when necessary), surface wash, with a dilute solution of stannous chloride sensitized, wash, and then mixed with silver plating solution and restore liquid impregnated surface immediately, mirror formed after the wash, followed by copper and protective paint. Vacuum evaporation method is to clean the glass, placed in 0.1~10 Pa of vacuum evaporation devices, the spiral filament power, generated heat spiral aluminum vaporize, deposited in formed on the surface of the mirror glass. Can also be used for electron guns instead of tungsten wire heating. Vacuum evaporation or smooth metal surface can be processed into a mirror.
