Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Straight grain with cathedral patterns and some irregularity around knots. This specific sample is a flat-cut veneer applied to a curved substrate.
Color Description
Heartwood ranges from light to dark chocolate brown. This sample shows warmth and consistent tone typical of steamed walnut, which bleeds the darker heartwood color into the palersapwood. It will likely lighten over time with UV exposure.
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, veneer, interior paneling, gunstocks, and turned objects.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$12.00 - $20.00 per board foot for solid lumber; veneer cost varies by application.
Wood Age Estimate
Modern (0-10 years); the uniform finish and application on a molded plywood/curved surface indicate contemporary manufacturing.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally sustainable.
Workability
Excellent workability with both hand and machine tools. Planes and glues well. Can occasionally have tearout if the grain is irregular. It develops a very smooth surface through sanding.
Notable Features
Distinctive mild, spicy scent when worked. High tannin content. It is prized for its shock resistance and dimensional stability.
Finish Recommendations
Works exceptionally well with oil-based finishes (tung oil, Danish oil) to enhance depth. Clear polyurethane or lacquer is also common for protection.
Identification Confidence
High; the characteristic chocolate-brown color, cathedral grain patterns, and use as a veneer on a mid-century style curved furniture piece are diagnostic of Black Walnut.
