Black Walnut
Juglans nigra • Hardwood
Grain Pattern
The sample exhibits a flat-sawn cathedral grain pattern with smooth, sweeping curves. The grain is generally straight but can be irregular, showing some subtle figure and a fine, uniform texture characteristic of high-quality walnut surfacing.
Color Description
Heartwood ranges from a light pale brown to a dark chocolate brown with darker brown streaks. Sapwood is characteristic pale yellowish-gray. The sample shows typical walnut luster and will likely develop a warm golden-brown patina with exposure to light over time.
Hardness Rating
1010 lbf (Medium)
Durability Rating
Highly durable regarding decay resistance, though susceptible to insect attack. It is one of the most durable domestic hardwoods in North America.
Common Uses
High-end furniture, cabinetry, gunstocks, interior trim, flooring, veneer, and turned objects.
Geographic Origin
Eastern United States and parts of Eastern Canada.
Market Value & Sustainability
Estimated Market Value
$10.00 - $15.00 per board foot depending on width, grade, and local availability.
Wood Age Estimate
The sample appears to be freshly surfaced or relatively young stock (under 5 years since milling), evidenced by the crisp edges and lack of deep oxidation or UV-induced fading.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable with FSC certification often available.
Workability
Excellent workability with both hand and machine tools. It planes smoothly, glues and finishes well, and holds screws and nails securely. It has a faint, pleasant odor while being worked.
Notable Features
Distinctive mild, spicy scent when worked. Contains juglone, which can be an irritant to some. Known for its exceptional dimensional stability and unique dark coloring among temperate hardwoods.
Finish Recommendations
Responds exceptionally well to oil-based finishes (like linseed or tung oil) which enhance the depth of the grain. Polyurethane, lacquer, and shellac are also excellent choices for added protection.
Identification Confidence
High. The combination of the chocolate-brown heartwood, pale sapwood transition, specific cathedral grain structure, and semi-porous texture is diagnostic for Juglans nigra.
