Tortoiseshell and Ebonised Wall Mirror

• 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.
• Provenance - A term used to describe the provable history of an antique or work of art, and thus an additional aid to verifying its authenticity. Provenance can have an inflating effect on the price of an item, particularly if the provenance relates to the early settlement of Australia, a famous person, or royalty. Less significant are previous sales of the item through an auction house or dealer.
• Ebonised - Timber that has been stained or lacquered black in imitation of ebony. The process has been used since the Renaissance, but is most commonly found in late 19th century furniture, sometimes gilded and turned in imitation of bamboo. Furniture with an ebonised finish is not currently in vogue, and this is reflected in the price for such pieces.
