Writing slope, c.1880 burr maple and burr walnut, with string…

• Burr - Burr (or in the USA, burl) is the timber from the knotted roots or deformed branch of the tree, which when cut, displays the small circular knots in various gradations of colour. It is always cut into a decorative veneer, most commonly seen as burr walnut on 19th century furniture.
• Maple - Maple, native to North America, is a dense heavy timber from light to yellow-brown in colour. It has very little distincive graining unless it is one of the variants such as birds-eye maple or burr maple, so was not used extensively for furniture in 18th and 19th century, where cabinetmakers and designers preferred timbers with more distinctive features such as mahogany, walnut, rosewood and oak.
  
  Birds-eye maple has a seres of small spots linked by undulating lines in the grain, is highly sough and is used as a decorative veneer. Burr maple has larger and irregular grain swirls than birds-eye maple.
