How mirrors are made?
Modern mirrors are made using this process. By taking liquid metals and allowing them to condense on a sheet of glass, one can get a surface far more reflective than anything achieved by polish.Making a mirror can be done at home with only a few supplies easily acquired at a local chemistry shop.With pure silver nitrate, distilled water, and ammonia, one can make a mirror virtually indistinguishable from those purchased at a store. The process (in abbreviated form) involves dissolving a small amount of silver nitrate in distilled water, then adding diluted ammonia until the mixture goes through distinct chemical changes. A second mixture is made using silver nitrate and Rochelle salts. This mixture must be boiled and filtered. By pouring these mixtures on to a very clean piece of glass sufficiently heated to the proper temperature, the silver will precipitate and form an even coating on the glass. After drying, one can coat the back of the silver with a solid paint to help prevent degradation of the silver. The result is a fully functional mirror.
