Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Straight grain with a medium texture; exhibits some minor cathedral peaking and slight irregular figuring indicative of a flat-sawn cut.
Color Description
Heartwood ranges from a lighter pale brown to a dark chocolate brown. This sample shows significant oxidation and surface staining; it will likely darken to a rich brown with age, though light exposure can eventually lighten walnut.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable; very resistant to heartwood decay, though susceptible to insect attack (sapwood).
Common Uses
Furniture, cabinetry, interior trim, flooring, gunstocks, veneer, and turned objects.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
Approximately $12.00 - $18.00 per board foot depending on grade and thickness.
Wood Age Estimate
20-40 years based on deep surface oxidation, dirt accumulation, and the presence of rough-cut milling marks visible on the side profile.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable.
Workability
Generally easy to work with hand and machine tools. It planes smoothly, glues well, and takes finishes excellently, though the dark dust can be an irritant.
Notable Features
Distinctive mild odor when being worked; known for excellent dimensional stability and shock resistance.
Finish Recommendations
Oil-based finishes (tung or linseed) to enhance the natural dark tones, or clear polyurethane for durability in high-wear areas.
Identification Confidence
Medium-High. The color palette, grain open-ness, and specific oxidation patterns are classic indicators of Juglans nigra, though surface grime obscures fine pore details.
