Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Usually straight, but can be irregular. Shows a medium texture with relatively large, open pores. Often features cathedral patterns when flat-sawn.
Color Description
Heartwood ranges from a lighter pale brown to a dark chocolate brown with darker brown streaks. Sapwood is pale yellow-gray to nearly white. Over time, it typically lightens slightly towards a more golden brown.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable to Very Durable; rated as very 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 (United States and Canada)
Market Value & Sustainability
Estimated Market Value
$10.00 - $18.00 per board foot depending on thickness, width, and figure
Wood Age Estimate
Modern cut (less than 10 years). The edges show clean mechanical shearing, and the lack of deep oxidation or graying suggests a relatively fresh or stored sample.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable in North America.
Workability
Generally easy to work with hand and machine tools. It planes well, though figured pieces may tear out. It glues, stains, and finishes very well.
Notable Features
Features a distinct, mild, spicy scent when being worked. Known for its excellent dimensional stability and shock resistance.
Finish Recommendations
Best suited for penetrating oils (Danish oil, Tung oil) to highlight grain, or a clear lacquer/polyurethane for protection. Darker stains are rarely used as the natural color is highly prized.
Identification Confidence
High; the characteristic chocolate-brown color, semi-porous grain structure, and typical pore distribution are hallmarks of Juglans nigra.
