Product description
Notice

The first mirror was probably the Water surface, where people could observe the image of their surroundings or also their "picture". Sometime in the 6th. millennium BC. n. l. there are polished OBSIDIAN plates that serve as mirrors. Od 2. century BC. n. l. metal mirrors are being made from polished bronze. These mirrors were generally used by the ancient Egyptians, Greeks and Romans. The Greeks and Romans sometimes used polished Silver for similar purposes.

The use of glass mirrors dates back to the Middle Ages. The first types of these mirrors appear inVenice, Italy, around 1300, from 16. century are already produced here in large quantities. the original method of production consisted of coating the back of the glass with a compound of mercury and tin. the first attempt to use a Silver solution for this purpose was made by the German chemist Justus von Liebig in 1836.
Gradually, different methods of production were developed, depending on the way the Silver salts were reduced to metallic Silver.
Today, a Silver nitrate solution is used, which is poured on the surface of the glass and left for about 1 hour. During this time, Silver nitrate is gradually reduced to metallic Silver. This layer is dried, covered with Shellac and painted with the characteristic brown colour.Recently, aluminium has also been used for the production of mirrors, which has, among other things. has the advantage of better resistance to corrosion (oxidation).

Mirrors are also made for industrial and scientific purposes. These are often made by evaporating Silver, rhodium or aluminium and precipitating them on the front surface of the cut glass in a vacuum. The reflective layer reaches a thickness of about 0.1 micrometer and must be surface protected (silicon).
