19th Century French Neo-Classical Clock Garniture

• Onyx - Onyx is a form of agate, used from antiquity and popular again in the 1920s and 30s. European onyx is generally green, but can be many other colours, and can contain bands of black and/or white.
  
  This multicoloured stone is widely used for table tops, lamp bases and in jewellery. Some types of onyx are also used for cameos of which the upper white layer is cut away to reveal the colour beneath.
• Neo Classical - The period or style, known as "neo-classical", was based on Greek and Roman designs and motifs, and is usually associated with the influence of the four Adam brothers, but principally Robert Adam, the second oldest of the brothers, who were architects and designers, active in the latter half ot the 18th century (1760s to 1790s).
  
  Born in Scotland in 1728, Robert Adam spent time in Italy studying and his designs are influenced by the finds made during the excavation of Pompei.
  
  When he returned to England he became the Court Architect to George III (1738-1820).
  
  In turn, designs by Adam then influenced Hepplewhite.
  
  Neo-classical ornamentation is characterised by use of classical urns, palmettes, mythical creatures such as the sphinx and griffin, ram's heads, swags, scrolling foliage, and use of the Greek key pattern.
• Ormolu - Ormolu was popular with French craftsmen in the 18th and 19th century for ornamental fittings for furniture, clocks and other decorative items. True ormolu is gilt bronze, that is bronze that has been coated with gold using a mercury amalgam. Due to the health risks associated with using mercury, this method of creating ormolu was discontinued in France in the 1830s. A substitute was developed consisting of about 75% copper and 25% zinc, however it was inferior to the bronze version. It was often lacquered to prevent it tarnishing.
