Swedish Birch Table with City Hall Intarsia Motif

• Intarsia - When used in relation to wooden items, intarsia is the Italian term for inlaying, where the background timber is cut away and and a selection of timbers of different colours and grains are inserted to form a picture or pattern.
• Birch - Birch is a Northern Hemisphere hardwood, closely related to the beech/oak family, and was a timber popular with 18th century craftsmen. Because of the blonde-golden colour of the grain when polished and its close grain, as a veneer it is often used as a substitute for satinwood where cost savings are required. From the late 18th century cabinetmakers in Russia and Eastern Europe used it in the solid for chairs and other furniture.
  
  Karelian birch is birch with a burr grain that resembles marble, from the Karelia region between Finland and Russia. Because only 30% to 40% of seeds result in trees with Karelian birch features, and the fact that it is very slow growing, the timber is very expensive.
• 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.
