Juglans nigra • Hardwood
Grain Pattern
Principally straight grain with some cathedral arching; features wavy live edge, occasional knots, and subtle curly figure or 'crotch' figuring near the epoxy interface.
Color Description
Heartwood ranges from light pale brown to dark chocolate brown with darker streaks. This sample shows lighter sapwood and steamed-effect tones. Tends to yellow or lighten over time with UV exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable to Very Durable regarding decay resistance; susceptible to insect attack (powder post beetles).
Common Uses
High-end furniture, cabinetry, veneer, gunstocks, interior trim, flooring, and live-edge river tables with resin.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$12.00 to $25.00 per board foot depending on thickness, width, and figure.
Wood Age Estimate
Modern lumber; likely kiln-dried and processed within the last 1-5 years based on the crisp surface and resin integration.
Sustainability Status
Least Concern (IUCN); widely available and not CITES listed; commonly FSC certified.
Workability
Excellent workability with both hand and machine tools. It planes smoothly, holds glue well, and finishes to a high luster. Can have a mild, distinct scent when worked.
Notable Features
Distinctive walnut scent; known for its stability and medium weight. Contains juglone which can be an allergen for some woodworkers.
Finish Recommendations
Penetrating oils (thistles, linseed, or tung) or clear polyurethane to highlight grain. Epoxy-resin integration requires mechanical sanding to high grits (400+) for a seamless bond.
Identification Confidence
High; the grain density, specific pore structure visible in the flat-sawn sections, and the characteristic pale-to-chocolate color transitions are diagnostic of Juglans nigra.
