• Polychrome - Made or finished in many colours. For furniture, it is used to indicated a painted finish.
• Embossed / Repousse - Embossing, also known as repousse, is the technique of decorating metal with raised designs, by pressing or beating out the design from the reverse side of the object.It is the opposite of chasing, where the decoration is applied from the front. An embossed or repoussed object may have chasing applied to finish off the design.
• Tortoiseshell - Tortoiseshell is a translucent material that comes from the horny carapace of a certain types of turtles, including the hawksbill turtle. It is often therefore mounted on a colour underground - often red - or inlaid with gold or silver thread, as seen in Boulle furniture.
  
  The texture and colour nuances of the material are extremely important. Heated tortoiseshell can easily be formed into various shapes. Like other natural materials, tortoiseshell becomes more beautiful with use. In a time before plastic, tortoiseshell was widely used for small objects such as combs and powder compacts.
  
  In 1973, the trade of tortoiseshell worldwide was banned under CITES (The Convention on International Trade in Endangered Species). Prior to importing or exporting items containing tortoiseshell a CITES permit must be obtained. Tortoiseshell items cannot be traded on Ebay.
  
  "Faux tortoiseshell", another case of man initiating nature, is made from old-style plastics such as celluloid and cellulos and is coloured with red, yellow and brown spots to imitate the genuine article. It is commonly used in glasses frames, musical instruments and costume jewellery.
• Fusee - The fusee movement was used in clocks and pocket watches from the mid 17th century. The fusee is a cone shaped drum within the works that is linked to the barrel of the spring, usually by a length of chain.
  
  As the mainspring loses its tension over time, the cone shaped barrel compensates for this by increasing the tension, by pulling the mainspring tighter, thus ensuring the time remains constant.
  
  Use of the fusee in clocks was superseded by the "going barrel" in the mid 19th century and for pocket watches at the beginning of the 19th century.
  
  The fusee continued to be used in marine chronometers until the 1970s.
• 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.
• Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
