Lavatory Mirrors
During Greco-Roman antiquity and throughout the European Middle Ages mirrors were crafted from highly polished convex disks of bronze, tin or silver; which resulted in a suitably reflective surface. The method of backing glass with a thin sheet of reflecting metal, an amalgam of tin and mercury became common practice in Venice during the 16th century. In 1835, Justus von Liebig originated modern mirror making techniques by developing the process of coating a glass surface with metallic silver.
