Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Principally straight with some cathedral figure and semi-open pores. Narrow vessel lines are visible on the surface, typical of walnut's diffuse-porous structure.
Color Description
Medium to dark chocolate brown heartwood with hints of purplish-grey. The sample shows a darkened patina and slight ambering, typical of age and UV exposure on walnut.
Hardness Rating
1010 lbf (Medium)
Durability Rating
Durable; highly resistant to heartwood decay, though susceptible to insect attack (sapwood).
Common Uses
High-end furniture, cabinetry, veneer, interior paneling, gunstocks, and turned objects.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$12.00 - $18.00 per board foot depending on width and figure quality.
Wood Age Estimate
30-50 years based on the depth of the patina, surface oxidation, and the wear patterns in the existing finish.
Sustainability Status
Stable population; not listed in CITES Appendices or on the IUCN Red List; widely available with FSC certification.
Workability
Excellent workability with both hand and machine tools. Glues, stains, and finishes well, though it can occasionally produce tearout on figured sections.
Notable Features
Distinctive mild, spicy scent when worked. Known for its exceptional dimensional stability and fine, uniform texture.
Finish Recommendations
Oil-based polyurethane or lacquer suggested to enhance natural depth; clear wax or shellac works well for a traditional antique look.
Identification Confidence
High. The rich chocolate color, specific grain pore structure, and characteristic patina are consistent only with American Black Walnut.
