George H Scales' Oak Roll-Top Desk by Archibald Stewart & Co

• Oak - Native to Europe and England, oak has been used for joinery, furniture and building since the beginning of the medieval civilisation. It is a pale yellow in colour when freshly cut and darkens with age to a mid brown colour.
  
  Oak as a furniture timber was superceded by walnut in the 17th century, and in the 18th century by mahogany,
  
  Semi-fossilised bog oak is black in colour, and is found in peat bogs where the trees have fallen and been preserved from decay by the bog. It is used for jewellery and small carved trinkets.
  
  Pollard oak is taken from an oak that has been regularly pollarded, that is the upper branches have been removed at the top of the trunk, result that new branches would appear, and over time the top would become ball-like. . When harvested and sawn, the timber displays a continuous surface of knotty circles. The timber was scarce and expensive and was used in more expensive pieces of furniture in the Regency and Victorian periods.
• Kneehole - A recessed section, mainly found on Georgian desks and dressing tables, which does not go through the full depth of the item, and usually terminates in a cupboard at the back.
• Tambour - A form of folding shutter formed by narrow widths of wood with the flat side glued to canvas, and used on some writing desks, sideboards and other cabinets.
  
  The tambours may run vertically and enclose some stationery compartments, such as in a lady's writing desk. Or the tambours may run horizontally, such as in a Cutler desk, and form an enclosure for the whole of the writing surface.
