Verre églomisé
Technique of applying gold or silver foil to the back of a piece of glass and engraving it with a needle before placing black or another contrasting color behind the foil. This was then enclosed with a second layer of glass or a coating of varnish to give a mirrored appearance. Verre églomisé was used as far back as the Roman era but was revived in the 18th century by the French decorator Jean-Baptiste Glomy.
