Ormolu
Chinese porcelains mounted with Parisian gilt-bronze ("ormolu") in neoclassical taste, late 18th century (Musée Nissim de Camondo, Paris)

Ormolu /ˈɔrməluː/ (from French or moulu, signifying ground or pounded gold) is an 18th-century English term for applying finely ground, high-karat gold in a mercury amalgam to an object of bronze. The mercury is driven off in a kiln (leaving behind a gold-colored veneer). The French refer to this technique as bronze doré; in English, it is 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.

Due to exposure to the harmful mercury fumes, most gilders did not survive beyond 40 years of age, .

No true ormolu was produced in France after around 1830 because legislation had outlawed the use of mercury. Therefore, other techniques were used instead but nothing surpasses the original mercury-firing ormolu method for sheer beauty and richness of colour.[1] Electroplating is the most common modern technique. Ormolu techniques are essentially the same as those used on silver, to produce silver-gilt (also known as vermeil).

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. From the 19th century the term has been popularized to refer to gilt metal or imitation gold.[2]

Gilt-bronze is found from antiquity onwards across Eurasia, but especially in Chinese art, where it was always more common than silver-gilt, the opposite of Europe.

Craftsmen principally used ormolu for the decorative mountings of furniture, clocks, lighting devices, and porcelain. The great French furniture-designers and cabinetmakers, or ébénistes, of the 18th and 19th centuries made maximum use of the exquisite gilt-bronze mounts produced by fondeurs-ciseleurs, or "founders and finishers", such as the renowned Jacques Caffieri (1678–1755), whose finished gilt-bronze pieces were almost as fine as jeweler's work. Ormolu mountings attained their highest artistic and technical development in France.

Similarly fine results could be achieved for lighting devices, such as chandeliers and candelabra, as well as for the ornamental metal mounts applied to clock cases and even ceramic pieces. In the hands of the Parisian marchands-merciers, the precursors of decorators, ormolu or gilt-bronze sculptures could be used for bright, non-oxidizing fireplace accessories or for Rococo or Neoclassical mantel- or wall-mounted clock cases - a specialty of Charles Cressent (1685–1768) - complemented by rock-crystal drops on gilt-bronze chandeliers and wall-lights.

The bronze mounts were cast by lost wax casting, and then chiseled and chased to add detail. Rococo gilt-bronze tends to be finely cast, lightly chiseled, and part burnished. Neoclassical gilt-bronze is often entirely chiseled and chased with extraordinary skill and delicacy to create finely varied surfaces.

The ormolu technique was extensively used in the French Empire mantel clocks, reaching its peak during this period.[3]

Chinese and European porcelains mounted in gilt-bronze were luxury wares that heightened the impact of often-costly and ornamental ceramic pieces sometimes used for display. Chinese ceramics with gilt-bronze mounts were produced under the guidance of the Parisian marchands-merciers, for only they had access to the ceramics (often purchased in the Netherlands) and the ability to overleap the guild restrictions.[citation needed] A few surviving pieces of 16th-century Chinese porcelains respectfully mounted in contemporary European silver-gilt, or vermeil, show where the foundations of the later fashion lay.

From the late 1760s, Matthew Boulton (1728–1809) of Birmingham produced English ormolu vases and perfume-burners in the latest Neoclassical style. Though the venture never achieved financial success, it produced the finest English ormolu. In the early 19th century fine English ormolu came from the workshops of Benjamin Lewis Vulliamy.

In France, the tradition of neoclassic ormolu to Pierre-Philippe Thomire (1751–1843) was continued by Lucien-François Feuchère. Beurdeley & Cie. produced excellent ormolu in rococo and neoclassical styles in Paris, and rococo gilt-bronze is characteristic of the furniture of François Linke.
