Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Straight grain with a medium texture; displays a slight coarse feel due to large pores. This sample shows a cylindrical turning or log section with fine growth ring lines and subtle variegated dark streaks.
Color Description
Rich dark brown heartwood with hints of chocolate and grey. The surface shows some oxidation (graying) on the ends. It typically lightens over time with UV exposure, moving toward a golden brown patina.
Hardness Rating
1010 lbf (Medium)
Durability Rating
Durable; very resistant to heartwood decay, though susceptible to insect attack (powderpost beetles).
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
$10.00 to $18.00 per board foot depending on width and figure.
Wood Age Estimate
Fresh to slightly aged (1-3 years). The rough texture and lack of deep heavy patina suggest recent harvesting or milling without significant indoor aging.
Sustainability Status
Widely available and sustainable; not CITES listed. IUCN classifies as 'Least Concern'.
Workability
Excellent workability with both hand and machine tools. It glues, stains, and finishes very well, though it can occasionally have irregular grain that causes minor tearout during planing.
Notable Features
Distinctive mild, spicy nut-like scent when being worked. Known for its shock resistance and dimensional stability. Contains juglone which can be an allergen for some.
Finish Recommendations
Best suited for penetrating oils (Danish or Tung oil) to highlight the deep grain, or clear polyurethane/lacquer to preserve the dark color.
Identification Confidence
High; the characteristic deep brown color, pore structure, and growth ring patterns are classic indicators of Juglans nigra, especially in a North American workshop context.
