What materials are mirrors made of ?

Mirror glass, also known as mirror, refers to glass products with extremely high reflectivity formed by chemical or physical methods on the surface of the glass.

Mirror glass, also known as coated glass or coated glass, is made from organic or inorganic compounds such as gold, silver, copper, iron, tin, titanium, chromium, or manganese as raw materials. It uses methods such as spraying, sputtering, vacuum deposition, and vapor deposition to form an oxide coating on the surface of the glass.

There are various colors for the coating of mirror glass, commonly used including gold, silver, gray, and antique bronze. This coated glass has unidirectional penetration of the line of sight, meaning that the line of sight can only be viewed from the coated side to the uncoated side.
