Copper-free Silver Mirror Production Process
1. Flushing glass
The polished flat glass is rinsed with heated distilled water. Since the minerals in tap water can affect the mirroring effect during the silver plating process, the entire cleaning process cannot be done directly with tap water.
2. Silver plating preparation
Since silver itself has no way to adhere directly to the glass surface, the factory makes the mirror by first spraying a tiny amount of stannous chloride solution onto the flat glass to create a stannous ion sensitized layer on the surface.
