Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Principally straight grain with visible cathedral patterns near the center of the image. Features some slight irregular swirl and small tight knots or bark inclusions typical of flat-sawn planks.
Color Description
Creamy-white sapwood transitions to a light chocolate-brown heartwood. The sample exhibits a medium luster and subtle chatoyance typical of Walnut. Over time and light exposure, it will likely lighten to a more golden-brown hue.
Hardness Rating
1010 lbf (Medium)
Durability Rating
Durable to Very Durable. Highly resistant to heartwood decay, though sapwood is susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, veneer, interior paneling, gunstocks, small specialty wood objects, and flooring.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
Approximately $12.00 - $18.00 per board foot depending on width and grade (FAS).
Wood Age Estimate
Modern processing (0-10 years). The surface appears freshly sanded or finished with a matte coating, showing no significant oxidation or historical patina from long-term use.
Sustainability Status
Not listed in the CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable in North America.
Workability
Excellent workability with both hand and machine tools. Planes and glues well. Responds exceptionally well to steam bending. Some care is needed to avoid tearout on figured sections.
Notable Features
Distinctive mild, spicy scent when being worked; contains juglone, which can be an irritant; prized for its dimensional stability and shock resistance.
Finish Recommendations
Oil-based finishes (tung oil or linseed oil) enhance its natural color and depth. Polyurethane or lacquer are recommended for durable surfaces like table tops.
Identification Confidence
High. The combination of the distinct color transition from sapwood to heartwood, the specific open pore structure visible in the cathedral grain, and the overall chocolate/tan palette is characteristic of Juglans nigra.
