Black Walnut (Weathered/Reclaimed)
Juglans nigra • Hardwood / Reclaimed
Grain Pattern
Straight to slightly irregular with visible checks and cracks; flat-sawn appearance with diffuse-porous structure and some spalting or mineral streaks.
Color Description
Heartwood is typically dark brown, but this weathered sample shows a grayish-tan oxidation patina. Sapwood is pale yellow-gray. Low luster due to surface weathering and dirt accumulation.
Hardness Rating
1,010 lbf (Medium Hardness)
Durability Rating
Durable to Very Durable regarding decay resistance; heartwood is highly resistant to rot though sapwood is susceptible to insect attack.
Common Uses
Furniture, cabinetry, gunstocks, interior trim, flooring, and decorative veneer. This specific piece appears to be a rustic bowl blank or reclaimed beam segment.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$10.00 - $15.00 per board foot for select grade; reclaimed or character-grade pieces may vary.
Wood Age Estimate
30-50 years based on the deep oxidation, surface checking, and blocky bark texture suggesting it was harvested and left to air-dry for a significant period.
Sustainability Status
Stable; non-CITES listed and classified as Least Concern by the IUCN, though populations are monitored for Thousand Cankers Disease.
Workability
Generally easy to work with both hand and machine tools. It glues, stains, and finishes well, though the weathered cracks in this sample may cause snagging or tearout during planing.
Notable Features
Distinctive faint, nutty odor when freshly cut; contains juglone which can be an irritant to some; known for excellent dimensional stability once seasoned.
Finish Recommendations
Penetrating oils (tung or linseed) or polyurethane to stabilize the weathered surface. Sanding through the oxidized layer will reveal the classic chocolate brown beneath.
Identification Confidence
Medium-High. The bark texture (alligator-skin pattern), the color of the oxidized grain, and the specific checking patterns are highly characteristic of Juglans nigra.
