Ormolu

n. imitation gold, metallic alloy used in decoration because of its resemblance to gold

Ormolu (from French or moulu, signifying gold ground or pounded) is an 18th-century English term for applying finely ground, high-karat gold to an object in bronze. The French refer to this technique as bronze doré, which is used to this day though the item may be merely painted with a gold-tone paint. The modern term in English is gilt bronze, which bears no relation to ormolu in process or materials. A later substitute of a mixture of metals resembling ormolu was developed in France and called pomponne, though, confusingly, the mix of copper and zinc, sometimes with an addition of tin, is technically a type of brass. Actual ormolu pieces by strict definition are rare, as they were no longer produced after the 1830s because of their impractical cost and health risks.
