What material and craft is used for the mirror surface of the smart mirror?
The past and present of the mirror?
The mirror is made of glass as the main material, and other metals, plastics and other materials as the frame. The glass is cut, edge(and polished if necessary), and the surface is cleaned, and then sensitized with a stannous chloride solution. Then wash, and then mix the silver plating solution and reducing solution to immediatelyimpregnate the surface. After the mirror surface is formed, wash it off, then copper plating and apply protective paint.
At first, people made mirrors by sticking a piece of tin foil tightly on the glass, and then pour mercury, because mercury can dissolve tin and turn it into a viscous silver-white liquid "tin amalgam". The tin amalgam is tight. If you stick it tightly to the glass, it becomes a mirror, but this kind of mirror is too time-consuming, and the mirror surface is not too bright, so it is gradually replaced by the current process.
