Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Straight, though sometimes wavy or curly. The end grain shows semi-ring-porous structure with visible growth rings and occasional cathedral patterns on the face grain.
Color Description
Heartwood ranges from light brown to a dark chocolate brown with darker brown streaks. Sapwood is pale yellow-gray to nearly white. Wood darkens slightly with age and develops a rich patina.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Very Durable; highly resistant to heartwood decay, though sapwood is susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, gunstocks, interior trim, flooring, veneer, and wood turning.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
Approximately $10.00 to $15.00 per board foot for live-edge slabs or high-grade lumber.
Wood Age Estimate
The logs appear to be freshly or semi-recently milled (within 1-3 years) due to the intact bark and lack of deep silvering/oxidation on the end grain, although the exterior structure is aged.
Sustainability Status
Abundant; not CITES listed and classified as 'Least Concern' by the IUCN. Widely available with FSC certification.
Workability
Generally easy to work with both hand and machine tools. It glues, stains, and finishes well, though figured pieces can occasionally exhibit grain tearout during planing.
Notable Features
Distinctive mild, spicy scent when being worked. Known for its excellent dimensional stability and shock resistance.
Finish Recommendations
Penetrating oils or wiping varnishes are highly recommended to highlight natural depth and luster. Water-based finishes may require a sealer to prevent a 'washed out' look.
Identification Confidence
High; the combination of thick, deeply furrowed bark, characteristic dark heartwood transition, and semi-ring-porous end grain is diagnostic for North American Black Walnut.
