Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Straight to slightly irregular with a medium-coarse texture; visible open pores typical of the Juglans genus. No significant figure like burl or curl is present in this specific section.
Color Description
Heartwood ranges from light to dark chocolate brown with occasional grayish or reddish streaks. Sapwood is typically pale yellowish-gray. This sample shows a warm, medium-brown patina developed through oxidation and light exposure.
Hardness Rating
1010 lbf (Medium)
Durability Rating
Very Durable; highly resistant to heartwood decay, though sapwood is susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, interior paneling, gunstocks, veneer, and musical instruments.
Geographic Origin
Eastern North America (United States and Canada)
Market Value & Sustainability
Estimated Market Value
$10.00 - $15.00 per board foot (standard 4/4 select & better grade)
Wood Age Estimate
Based on the oxidation level and finished surface wear, the wood appears to be roughly 20-40 years old, likely part of a vintage furniture piece.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable in its native range.
Workability
Excellent workability with both hand and machine tools. It planes well, glues easily, and takes stains and finishes exceptionally well, though the open grain may require filling for a glass-smooth finish.
Notable Features
Distinctive mild, spicy scent when worked. High contrast between heartwood and sapwood. Contains juglone, which can be an allergen for some woodworkers.
Finish Recommendations
Oil-based finishes (tung oil or linseed oil) enhance its natural color and chatoyance; polyurethane or lacquer provide durability for heavy-use surfaces.
Identification Confidence
High. The characteristic pore structure, color variations, and grain density are consistent with North American Black Walnut, specifically used in furniture applications.
