Black Walnut
Juglans nigra • Hardwood

Grain Pattern
Straight grain with a medium texture; displays a slight cathedral pattern typical of flat-sawn lumber
Color Description
Heartwood ranges from a deep chocolate brown to a lighter pale brown; sapwood is pale yellow-gray to nearly white. Typically darkens with age and develops a rich patina
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Very Durable; highly resistant to heartwood decay, though susceptible to insect attack
Common Uses
High-end furniture, cabinetry, veneer, gunstocks, interior paneling, and wood turning
Geographic Origin
Eastern North America (United States and Canada)
Market Value & Sustainability
Estimated Market Value
$12.00 - $20.00 per board foot depending on grade and width
Wood Age Estimate
The visible patina and oxidation suggest the sample is likely 10-25 years old if finished
Sustainability Status
Not listed in 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 very well, though it can occasionally have irregular grain that causes tearout
Notable Features
Distinctive mild odor when being worked; known for its high shock resistance and dimensional stability
Finish Recommendations
Penetrating oils or wiping varnishes are recommended to highlight the natural grain and chatoyance; polyurethane for higher durability
Identification Confidence
Medium; the color profile and grain structure are highly characteristic of Juglans nigra, though low image resolution makes definitive pore analysis difficult
