Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Straight grain with a moderate, open texture. Some subtle cathedral patterns are visible due to the flat-sawn orientation, with fine pores and a slight wavy figure in the darker streaks.
Color Description
The heartwood is a grayish-brown with darker chocolate-brown and purplish streaks. The sapwood is creamy white (visible on the right edge). It has a dull to semi-lustrous finish and will typically lighten and become more golden-yellow with age and UV exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable; highly resistant to decay and rot, though sapwood is susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, veneer, gunstocks, interior paneling, flooring, and musical instruments.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$10.00 to $18.00 per board foot depending on thickness and quality grade.
Wood Age Estimate
Relatively fresh and kiln-dried; limited oxidation or patina suggests it was milled within the last 1-3 years.
Sustainability Status
Generally sustainable; not CITES listed and classified on the IUCN Red List as Least Concern. Readily available as FSC certified.
Workability
Excellent workability with both hand and machine tools. Planes and sands easily, takes glue and fasteners well. Steam-bends moderately well.
Notable Features
Distinctive mild, spicy scent when worked. Contains juglone which can be an allergen for some. Known for its shock resistance and dimensional stability.
Finish Recommendations
Best suited for clear natural oils (like tung or linseed oil) or polyurethane to enhance the chatoyance. No staining is required as the natural color is highly prized.
Identification Confidence
High; the combination of chocolate-brown heartwood, distinct creamy sapwood transition, and semi-porous grain structure is classic for Juglans nigra.
