Ormolu - (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.

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. 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).

Parquetry - is a geometric mosaic of wood pieces used for decorative effect. The two main uses of parquetry are as veneer patterns on furniture and block patterns for flooring. Parquetry patterns are entirely geometrical and angular—squares, triangles, lozenges.

The word derives from the Old French parchet , literally meaning "a small enclosed space". Large diagonal squares known as parquet de Versailles were introduced in 1684 as parquet de menuiserie to replace the marble flooring that required constant washing, which tended to rot the joists beneath the floors.

Such parquets en lozange were noted by the Swedish architect Daniel Cronström at Versailles and at the Grand Trianon in 1693. Timber contrasting in color and grain, such as oak, walnut, cherry, lime, pine, maple etc. are sometimes employed; and in the more expensive kinds the richly coloured mahogany and sometimes other tropical hardwoods are also used.
