(French: or moulu, “ground gold”). The term ormulu is used for objects of metal (often bronze) that have been fire-gilded with an amalgam of  ground gold and mercury. Ormolu was used widely from the mid-17th century for decorative furniture mounts, clocks, mirror frames, chandeliers, and other objects. It passed out of use in the later 19th century, as it was replaced by less poisonous gilding techniques. Pronunciation here. Web resource here.
