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, as on these lovely candelabra.   The fine cut crystal is shaped and polished through a cutting process resulting in a brilliant, clear end.  Cobalt blue porcelain was associated with royalty and luxury and is used widely in French antique pieces.
