Walnut is unique because there are no other North American species of wood with the same distinct chocolate brown colored heartwood.
The woods beautiful color and grain gained popularity for furniture, flooring and interior woodwork applications. The wood’s rich tones make for excellent doors and paneling.Walnut machines easily due to its middle grade hardness, and it is very gentle on cutting edges. It holds detail well and finishes beautifully to a deep, rich brown.
Freshly milled Walnut exhibits many different color hues, from deep browns and purples to light creams. The process of steaming Walnut evens out some of those color variations and creates a much more uniform and mellow chocolate color. Over time and with oxidation and UV exposure, Walnut lightens in color, and it blends well with most other species.
