The mirror. the mirror we know invented by Justus von Liebig in 1835. This is called "mirror silver glass" , a mirror in which metal is attached to the glass by chemical means, while the metal is strangled. Although the mirrors used in the past were born thousands of years BC. So long ago people did not know yet about the connection between the glass and the metal that would be reflected in an optical way. In 4000 BC in Mesopotamia and 1000 years later in ancient Egypt, polished copper mirrors were used. Another thousand years, around 2000 BC, created mirrors from polished stones in Central America. Around those times, in distant China, bronze mirrors were created.
