Mirror can tell us how exactly we look. When people did have a mirror they are used to peep into the still pool of water and see their own reflection along with the reflection of sky, tree, and many more surrounding them. But when there are ripples in the water, the reflection will be dissolved. Smooth surface is necessary for the clean reflection. People tried to find smooth polished surface for clean image. In ancient times, Greece, Egypt, and Rome mirrors were necessary part of common daily life. Mirrors are made up of polished copper later popped up in Mesopotamia (New Iraq) and Egypt about 4000 B.C. In Central and South America, polished, polished stone mirror were found around 2000 B.C In China, Bronze mirrors were manufactured from about 2000 B.C. Mirrors are made up of other metal mixtures were produced in China and India.

However, Glass was found most desirable material for mirrors due to its smooth surface.  To increase the reflectivity, it necessitated coating it with metal. It is said that metal coated glass mirror were invented in Sidon (Now Lebanon). Venetian were the first people to know about how to make mirrors of glass baked with mercury and tin in the sixteenth century.

The invention of silvered glass mirror is credited to German Chemist, Justus Vonliebig in the year 1835. In modern time glass mirrors are most often coated with silver or aluminum.
