Bronze d'oré, also known as ormolu or gilt bronze, was a decorative finish used on luxury furnishings in the 18th and 19th centuries. An application of finely ground high carat gold and mercury amalgam was placed on objects of bronze. When subjected to extremely high heat, the mercury evaporated, leaving behind a lustrous coating of gold.

 

Gilt-bronze mounts were used to protect furniture from damage and to emphasize form, and to mount beautiful objects such as candelabra, clocks, lamps, pedestals and porcelain vases.
