Black Walnut

Juglans nigraHardwood

Black Walnut

Grain Pattern

Generally straight but can be irregular; the sample exhibits a tight, fine grain with subtle cathedral patterns visible along the curved molded edges.

Color Description

Medium to dark chocolate brown heartwood; the sapwood is typically pale yellow-gray but is not visible here. The sample shows a rich, warm patina with moderate luster, characteristic of naturally aged and finished walnut.

Hardness Rating

1,010 lbf (Medium)

Durability Rating

Durable; highly resistant to heartwood decay, though susceptible to insect attack (powder post beetles).

Common Uses

High-end furniture, cabinetry, veneer, gunstocks, interior trim, and specialty turned items such as this mirror frame.

Geographic Origin

Eastern United States and parts of Southern Canada.

Market Value & Sustainability

Estimated Market Value

$12.00 - $20.00 per board foot for kiln-dried FAS grade lumber.

Wood Age Estimate

50-80 years old, based on the deep oxidation of the finish, the style of the profile molding, and the visible wear patterns and natural darkening.

Sustainability Status

Not listed in CITES Appendices; IUCN status of Least Concern. Generally considered very sustainable with wide availability.

Workability

Excellent workability with both hand and machine tools. It planes and sands very smoothly and holds finishes exceptionally well, though it can occasionally produce tearout in pieces with irregular grain.

Notable Features

Distinctive mild, spicy scent when worked. Walnut is prized for its dimensional stability and strength-to-weight ratio. Finely texture with diffuse-porous anatomy.

Finish Recommendations

Traditional lacquer or hand-rubbed oil finishes (tung or linseed) are best to highlight the natural depth and chatoyance. This piece appears to have a nitrocellulose lacquer or shellac finish.

Identification Confidence

High; the deep chocolate brown color, pore structure, and the characteristic way the grain takes the dark finish in the molded recesses are classic diagnostic features of North American Black Walnut.
