Appearance: There is a distinct difference in color between the nearly white sapwood of walnut and the heartwood, which ranges in color from a deep, rich dark, almost chocolate brown to a purplish black. The wood is especially valued for its wavy, curly and mottled figures. The wood surface is generally fairly dull, though it may develop a lustrous patina after many years in use.
Properties: Walnut is one of the most durable of the domestic commercial woods, even under conditions favorable to decay.
Principal uses: Frequently used as a highlight material for borders and other inlay techniques. It is typically found in wood flooring, veneer, paneling, fixtures, furniture, cabinets and novelty items. In addition, it is superior to all other woods for gunstocks because of the way it keeps its shape.
