A mirror is flat or curved surface usually produced of glass that has had a reflective coating applied to it. Mirrors are also used in technology and
they are an important component in scientific instruments such as telescopes, industrial machinery, cameras and lasers.
People probably first started to look at their reflections in pools of water, streams and rivers which were the
first mirrors. The earliest man made
mirrors were from polished stone and mirrors made form black volcanic glass obsidian. Some examples of this kind of mirrors have been found in Turkey
dating back at least 6000 years. The Ancient Egyptians used polished copper to produce mirrors, and often the round face of the mirror would be
embellished with ornamentation. The Ancient Mesopotamians also produced polished metal mirrors and mirrors made from polished stone were known in
Central and South America from about 2000 BC. In China mirrors began to be made from metal alloys, a mixture of tin and copper called speculum metal
that could be highly polished to made a reflective surface as well as mirrors made of polished
bronze. Metal alloys or precious metals mirrors were
very valuable items in ancient times only affordable to the very wealthy.
It is believed that mirrors made of metal-backed glass this
type of mirror was first produced in Lebanon in the first century AD and the Romans made
crude mirrors from blown glass with lead backings.
