The earliest manufactured mirrors have been items of polished stone which include obsidian, a By natural means taking place volcanic glass. Samples of obsidian mirrors found in Anatolia (modern day-day Turkey) are actually dated to close to 6000 B.C.[3] Mirrors of polished copper were crafted in Mesopotamia from 4000 B.C.,[3] As well as in historical Egypt from around 3000 B.C.[4] Polished stone mirrors from Central and South The usa day from all around 2000 B.C. onwards.[three] In China, bronze mirrors were created from all over 2000 B.
