Rare Colonial Jarrah Chiffonier by Edwin F. Duffield

• Turning - Any part of a piece of furniture that has been turned and shaped with chisels on a lathe. Turned sections include legs, columns, feet, finials, pedestals, stretchers, spindles etc. There have been many varieties and fashions over the centuries: baluster, melon, barley-sugar, bobbin, cotton-reel, rope-twist, and so on. Split turning implies a turned section that has been cut in half lengthwise and applied to a cabinet front as a false decorative support.
• Corbel - An architectural term for a support for a projecting bracket, ostensibly supporting a beam or horizontal feature, but used in bookcases, sideboards and chests as a decorative element. Corbels are often carved with acanthus or other scrolling decoration.
• Patination / Patina - In broad terms, patination refers to the exterior surface appearance of the timber, the effect of fading caused by exposure to sunlight and air over the course of a century or more, changing the piece to a soft, mellow colour.
  
  As patina is very difficult to replicate, it is one of the most important guides to determining the age of furniture.
  
  Patina is also the term applied to the bloom or film found on old bronzes due to oxidisation.
• Column - An architectural feature sometimes used for decorative effect and sometimes as part of the supporting construction. Columns should generally taper slightly towards the top. They may be plain or decorated with carving, fluting or reeding. Columns may be fully rounded or, more commonly, half-rounded and attached with glue, screws or pins to the outer stiles of doors, or the facing uprights on cabinets and bureaux.
• Back Boards - As the name implies, the boards that back a piece of cabinet furniture such as a chest of drawers. The backing timber is usually of cheaper material like pine (often called 'deal' by the British trade), though in early Australian colonial days, red cedar was also used to back a piece. As cedar became scarcer during the later 19th century, craftsmen turned to kauri pine.
  
  On early furniture, made before the first half of the 19th century, the backboards were often chamfered at the edges and the wide boards slotted into grooves in a supporting central frame. In later furniture, the backboards were generally nailed or screwed into rebates cut directly into the carcase and the boards became much thinner and narrower.
  
  From about the first world war plywood was frequently used for cheaper pieces.
  
  Backboards are one important way of judging the age of a piece of furniture.
• Jarrah - A eucalypt, known by its aboriginal name jarrah, it grows only in the south-west of Western Australia. The timber is a dark red-brown in colour with similar grain and colouring to mahogany and was used extensively in house construction as well as for making furniture.
