Tortoise Shell Veneered Hall Table

• 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.
• Veneers - Veneers are thin sheets of well-figured timber that are glued under pressure to the surface of a cheaper timber for decorative effect, and then used in the making of carcase furniture.
  
  Early veneers were saw-cut so were relatively thick, (up to 2 mm) but is was realised that saw cutting was wasteful, as timber to the equivilent of the thickness of the saw was lot on each cut.
  
  A more efficient method was devised to slice the timber, either horizontally with a knife, or in a rotary lathe.
  
  Flame veneer, commonly found in mahogany or cedar furniture, is cut from the junction of the branches and main trunk. So-called fiddleback veneers, where the grain is crossed by a series of pronounced darker lines, is usually cut from the outer sections of the tree trunk.
  
  During the 17th and 18th centuries, and in much of the walnut marquetry furniture made during the latter part of the 19th century, the veneer was laid in quarters, each of the same grain, so that one half of the surface was the mirror image of the other.
  
  The use of veneer allows many other decorative effects to be employed, including stringing, feather banding, cross banding, and inlaid decorative panels in the piece. The carcase over which veneer is laid is usually of cheaper timber such as pine, oak or, sometimes in Australia during the first half of the 19th century, red cedar.
  
  The important thing to remember about veneers is that prior to about 1850 they were cut by hand, and were consequently quite thick - ranging up to about 2mm deep.
  
  From the mid-19th century veneers were cut by machines and were almost wafer-thin. This is a critical point when trying to judge the approximate age of veneered furniture.
