OK, so the The Palace of Versailles Hall of Mirrors isn’t a “small space” in the least, but it was one of the first architectural projects to feature new technology in mirror making. Built from 1678–1684, this great hallway incorporates seventeen mirror-clad arches that reflect the seventeen arcaded windows. Each arch contains twenty-one mirrors that were created by the Venetian Republic, who, at the time controlled the mirror monopoly. Mirrors were among the most expensive items sold during the 17th century. Thanks to Justus von Liebig and his advance in the modern techniques of silver-glass mirror making in 1835, we now have perfected the chemical process of coating a glass surface with metallic silver, which is the most widely known mirror making process used today. Life and design would be drastically different if it weren’t for mirrors, and here are just a few reasons why.
