Origin
Europe, Asia
Range
Central, Western and Southern Europe, cultivated in Asia Minor, North Africa, North India and China. Most appreciated within Europe is the French Walnut because of its exquisite color. Due to severe periods of frost in France in the last ten years a great many of the existing trees were damaged and thus are no longer suitable for the veneer industry. As a result, veneer production has fallen off greatly and good logs can only be obtained in isolated cases. Turkish, Italian, Spanish and Caucasian Walnut is available, but not so much in demand because of their highly conspicuous and distinct texture.
Uses
Sliced veneer and lumber used in high quality architectural woodwork. Only of significance for mass-produced furniture in Southern Europe.
Properties
The color is light to dark brown or mouse grey, often with dark growth lines. Certain periods of furniture are firmly associated with the use of this wood (for example, Queen Anne furniture in Great Britain). The trunks are generally dug out with the roots which are used to produce the choice head veneer.
Machining
Walnut can be worked with all tools without difficulty. Planed surfaces are very smooth.
Seasoning
As a rule Walnut can be dried without problems provided that the drying is not hurried.
Finishing
The decorative pattern is highlighted by silky luster varnish. This wood is also extremely suitable for polishing.
Jointing
Glue joints have high tensile strength. Screw joints hold firmly but should be pre-drilled.
