Bronze doré

A French 18th and 19th Century gilding technique of applying an amalgam of fine, high-carat gold with mercury to copper, brass, or most commonly bronze objects. The bronze is exposed to high heat in a kiln burning off the mercury leaving a thin gold coat behind that is adhered to the metal. Commonly used by the craftsmen, Fondeurs-ciseleurs (founders and finishers), for decorative mounts in furniture, clocks, candelabras, and porcelain. Due to the health hazards of mercury, the technique waned into the late 19th Century and was replaced by electroplating.

Sconce

A wall-mounted bracket light, typically with an upward-facing arm that holds, in antique sconces, an oil lamp or candle, or in modern examples, an electrified light. Antique sconces were used often in corridors or in pairs on both sides of an entryway. They featured a reflective backplate to intensify candlelight while keeping the candle a safe distance from the wall. They are commonly made of metals such as silver, bronze, or ormolu and became very decorative in the 18th Century.

Relief

Filigree

Primarily refers to fine, ornate metalwork (mainly in gold, silver, or copper), that is intricately patterned and used as ornamentation or embellishment, particularly in fine jewelry making.
