Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Generally straight but can be irregular; featured here with cathedral patterns and a visible knot with tight swirl figure. Semi-ring porous texture is visible.
Color Description
Heartwood is a rich, dark brown with some chocolate tones and darker streaks. Sapwood is typically pale yellow-gray. Naturally ages to a lighter golden brown; current sample shows significant oxidation and darkening due to age.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Very Durable; highly resistant to heartwood decay, though susceptible to insect attack (sapwood).
Common Uses
High-end furniture, cabinetry, gunstocks, interior paneling, veneer, and turned objects.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$12.00 - $20.00 per board foot depending on width and grade.
Wood Age Estimate
50-80 years. The deep oxidation, dark patina, and surface wear patterns suggest a vintage architectural or furniture component.
Sustainability Status
Abundant; not CITES listed or on the IUCN Red List. Widely available with FSC certification.
Workability
Excellent workability with both hand and machine tools. It planes smoothly, glues well, and takes a high polish, though it can have occasional grain tearout in figured sections.
Notable Features
Distinctive mild, spicy scent when worked. High tannin content. Relatively lightweight for its strength.
Finish Recommendations
Penetrating oils or wipe-on polyurethanes are recommended to highlight depth and chatoyance; shellac is also historically appropriate for this era of wood.
Identification Confidence
High; the deep chocolate color, characteristic pore structure, and specific cathedral grain pattern are quintessential markers of Juglans nigra.
