Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Straight to slightly irregular with a medium-coarse texture. This sample appears to be rift-sawn and exhibits a fairly consistent linear grain without strong cathedral patterns.
Color Description
Heartwood ranges from light pale brown to dark chocolate brown with darker streaks. This specific sample is relatively light, suggesting it may be near the sapwood transition or from a younger tree. It will develop a rich patina and lighten slightly to a more golden brown over time with UV exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Very Durable. Noted for its excellent decay resistance and dimensional stability, though sapwood is susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, gunstocks, interior trim, veneer, flooring, and musical instruments.
Geographic Origin
Native to Eastern North America (Central and Eastern United States).
Market Value & Sustainability
Estimated Market Value
$10.00 - $15.00 per board foot depending on grade and regional availability.
Wood Age Estimate
Relatively recent/modern (less than 10 years). The edges show clean machine cuts with minimal oxidation or darkening typically seen in air-dried or reclaimed lumber.
Sustainability Status
Not listed in CITES Appendices or the IUCN Red List of Threatened Species. Widely available and considered a sustainable choice with FSC certification frequently available.
Workability
Excellent workability with both hand and machine tools. It planes smoothly, holds nails and screws well, and glues reliably. It handles steam bending well.
Notable Features
Distinctive mild, spicy odor when being worked. Known for its exceptional finishing qualities and dimensional stability (it shrinks and swells less than most other hardwoods).
Finish Recommendations
Takes all finishes well. Danish oil or tung oil are recommended to enhance the natural grain and 'depth.' Polyurethane or lacquer can be used for increased protection.
Identification Confidence
High. The color palette, pore structure visible in the grain, and typical 'rift' appearance of the grain lines are highly characteristic of North American Black Walnut.
