Black Walnut

Juglans nigraHardwood

Black Walnut

Grain Pattern

Principally straight with typical cathedral figure at the bottom center; exhibits flat-sawn characteristics with some medium-texture open pores.

Color Description

Heartwood is medium to dark brown (currently appearing lighter/muted due to lack of finish and dust); sapwood is pale yellowish-white. It will darken or golden with oil and lighten over time with UV exposure.

Hardness Rating

1,010 lbf (Medium)

Durability Rating

Durable and very resistant to heartwood decay, though sapwood is susceptible to insect attack.

Common Uses

High-end furniture, cabinetry, gunstocks, interior paneling, veneer, turned objects, and specialty small wood items.

Geographic Origin

Eastern North America

Market Value & Sustainability

Estimated Market Value

$10.00 - $18.00 per board foot depending on width and grade (assuming FAS grade).

Wood Age Estimate

Freshly milled or recently surfaced (1-3 years since harvest); low oxidation suggests a relatively new cut despite the rough surface.

Sustainability Status

Not listed in the CITES Appendices or on the IUCN Red List; widely available and generally managed sustainably.

Workability

Excellent workability with both hand and machine tools; glues, stains, and finishes well. Occasional tearout can occur in figured sections.

Notable Features

Distinctive mild, sweet odor when worked; contains juglone which can be an irritant; prized for its balance of strength and weight.

Finish Recommendations

Oil-based finishes (tung oil or linseed oil) or clear polyurethane are highly recommended to bring out the deep chocolate tones and natural luster.

Identification Confidence

High; the color hue, specific cathedral grain pattern, and visible sapwood/heartwood transition are classic indicators of Juglans nigra.
