American walnut

To the genus walnut belong approx. 60 varieties, as impressive deciduous trees of 20-30 m indigenous to the Northern hemisphere.
The most familiar walnut wood comes from trees indigenous to Southeast Europe and the Balkans. However, because in these regions during the last decades, no systematic recultivation has been made, it leads increasingly to bottlenecks on the procurement side, in conjunction with enormous price increases. That’s why in the furniture industry mainly the American walnut is used.
These trees indigenous to North America are mainly solitary trees with stature heights of more than 40 m and stem diameters from 30 to 100 cm. The wood color is dark, ranging from greyish brown to purple brown. The wood is medium hard and the pores are of a medium size. In conjunction with the annual rings occurs a lovely wood structure surface. In the furniture manufacture and as interior decoration, walnut belongs to the finest and most prestigious woods, because of its interesting wood grain and its dark color. This color may vary significantly from stem to stem and makes necessary a special selection of the wood and the veneer.
As with all dark wood types, also walnut wood is characterized to fade and to yellow under the influence of ultraviolet light. This effect cannot be stopped completely even with an UV-filter in the varnish.
