Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Straight grain with occasional wavy patterns; flat-sawn surfaces showing some cathedral figure and moderate pore size (semi-ring porous).
Color Description
Heartwood ranges from light greyish-brown to deep chocolate brown. This sample shows typical oxidation and light-bleaching, resulting in a warmer, amber-brown tone over time. Low to medium luster.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable; highly resistant to heartwood decay, though susceptible to insect attack (sapwood).
Common Uses
High-end furniture, cabinetry, veneer, gunstocks, interior paneling, and turned items.
Geographic Origin
Eastern United States and Southern Ontario, Canada.
Market Value & Sustainability
Estimated Market Value
$10.00 - $15.00 per board foot for 4/4 select grade.
Wood Age Estimate
Estimated 40-70 years based on the furniture construction style, oxidation of the finish, and the specific wear patterns on the edges.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally sustainable.
Workability
Excellent workability with hand and machine tools. Planes and glues well; holds stains and finishes exceptionally well, though it can have occasional grain tearout.
Notable Features
Distinctive mild spicy scent when worked. High dimensional stability and prized for its rich color and finishing properties.
Finish Recommendations
Penetrating oils or wiping varnishes are best to highlight the grain depth. Polyurethane for high-wear furniture surfaces.
Identification Confidence
High; the open grain structure, characteristic brown-to-amber oxidation, and the specific pore distribution visible in the flat-sawn face are diagnostic of Juglans nigra in a furniture context.
