High-end furniture, cabinetry, gunstocks, interior trim, flooring, veneer, and turned objects.

Geographic Origin

Eastern United States and Ontario, Canada.

Market Value & Sustainability

Estimated Market Value

$10.00 to $18.00 per board foot depending on width and grade.

Wood Age Estimate

The visible surface wear, ambering of the finish, and fine scratches suggest a vintage sample, likely 30-50 years old.

Sustainability Status

Not listed in the CITES Appendices or on the IUCN Red List of Threatened Species; widely available and generally sustainable.

Workability

Easy to work with both hand and machine tools. Planes and glues well, holds nails and screws effectively, and steam-bends easily.

Notable Features

Faint, mild odor when being worked. Known for excellent dimensional stability and shock resistance.

Finish Recommendations

Takes all finishes well; oil-based finishes are preferred to enhance the deep brown color and natural figure.

Identification Confidence

Medium; the visible grain density, warm chocolate-to-amber transition, and diffuse-porous structure are characteristic of finished Black Walnut.
