Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Usually straight, but can be irregular or curly. The sample shows a mix of straight-grain rails with subtle cathedral patterns and some figure near the joints.
Color Description
Heartwood ranges from a light pale brown to a dark chocolate brown with even darker brown streaks. Color tends to lighten over time with UV exposure, developing a golden-brown patina. Sapwood is pale yellow-gray.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Very Durable; highly resistant to heartwood decay, though susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, gunstocks, interior paneling, veneer, turned objects, and musical instruments.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$12.00 - $20.00 per board foot depending on thickness and grade (Select & Better).
Wood Age Estimate
Modern construction (likely 5-15 years old) based on the hardware types, precision of the joinery, and consistent oxidation of the finish.
Sustainability Status
Not listed in the CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable with FSC options.
Workability
Excellent workability with both hand and machine tools. It planes and glues well, and holds nails and screws securely. Hardwood dust can be an irritant.
Notable Features
Distinctive mild, spicy scent when worked. Contains juglone which can be an allergen for some. Known for its exceptional dimensional stability and fine finishing qualities.
Finish Recommendations
Oil-based finishes (tung oil or linseed oil) enhance the depth and chatoyance; polyurethane or lacquer provide durability for furniture surfaces.
Identification Confidence
High; the chocolate brown heartwood, open-pore structure visible in the grain, and typical 'cathedral' figure are classic indicators of North American Black Walnut used in furniture.
