Ormolu - Gilt Bronze (from French 'or moulu', signifying ground or pounded gold) is an 18th-century English term for applying finely ground, high-carat gold in a mercury amalgam to an object of bronze.The mercury is driven off in a kiln leaving behind a gold-coloured veneer known as 'gilt bronze'.

The manufacture of true ormolu employs a process known as mercury-gilding or fire-gilding, in which a solution of nitrate of mercury is applied to a piece of copper, brass, or bronze, followed by the application of an amalgam of gold and mercury. The item was then exposed to extreme heat until the mercury burned off and the gold remained, adhered to the metal object.

After around 1830 because legislation had outlawed the use of mercury other techniques were used instead. Electroplating is the most common modern technique. Ormolu techniques are essentially the same as those used on silver, to produce silver-gilt.

Charles Cressent (1685–1768)
was a French furniture-maker, sculptor and fondeur-ciseleur of the régence style. As the second son of François Cressent, sculpteur du roi, and grandson of Charles Cressent, a furniture-maker of Amiens, who also became a sculptor, he inherited the tastes and aptitudes which were likely to make a finished designer and craftsman. Even more important perhaps was the fact that he was a pupil of André Charles Boulle. Trained in such surroundings, it is not surprising that he should have reached a degree of achievement which has to a great extent justified the claim that he was the best decorative artist of the 18th century. Cressent's distinction is closely connected with the regency, but his earlier work had affinities with the school of Boulle, while his later pieces were full of originality.
