Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Features a prominent cathedral grain pattern on a flat-sawn surface. The grain is generally straight but can be irregular; small knots and bird-peck or bark inclusions (like the dark pocket visible) are common.
Color Description
This sapwood-heavy sample displays creamy white to light tan tones with hints of grey. The darker streaks represent the chocolate-brown heartwood. It typically darkens slightly with UV exposure and develops a rich patina over time.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Highly durable regarding decay resistance, though sapwood is susceptible to insect attack. Heartwood is very resistant to rot.
Common Uses
High-end furniture, cabinetry, gunstocks, interior trim, flooring, veneer, and turned objects.
Geographic Origin
Eastern United States and parts of Eastern Canada.
Market Value & Sustainability
Estimated Market Value
$10.00 - $15.00 per board foot for select grades; lower prices for sapwood-heavy pieces.
Wood Age Estimate
Modern milling; appears to be kiln-dried stock, approximately 1-5 years post-processing based on lack of significant oxidation.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List of Threatened Species; widely available and generally managed sustainably.
Workability
Excellent workability with both hand and machine tools. It planes smoothly, glues well, and takes finishes exceptionally. Care must be taken to avoid tearout on irregular grain around inclusions.
Notable Features
Features a faint, characteristic mildly spicy scent when worked. Known for its shock resistance and dimensional stability. Dust can be a mild sensitizer; contains juglone.
Finish Recommendations
Oil-based finishes (like Danish oil) or polyurethane are recommended to highlight the grain. Clear coats help preserve the contrast between the lighter sapwood and dark heartwood.
Identification Confidence
High; the distinctive cathedral grain, pore structure, and the contrast between creamy sapwood and dark streaks are classic indicators of Juglans nigra.
