Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Generally straight but characterized here by a prominent cathedral figure from flat-sawing; shows medium texture and naturally coarse pores typical of the species.
Color Description
Heartwood is a medium to dark chocolate brown with occasional purplish or reddish streaks. Sapwood is pale yellowish-gray (not visible in this cut). Tends to lighten and become more golden-brown over time with UV exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable; very resistant to heartwood decay, though susceptible to insect attack (specifically powderpost beetles).
Common Uses
High-end furniture, cabinetry, veneer, gunstocks, interior trim, flooring, and small wood turned objects.
Geographic Origin
Eastern North America (United States and Canada).
Market Value & Sustainability
Estimated Market Value
$12.00 - $18.00 per board foot depending on thickness and width (4/4 vs 8/4 select and better).
Wood Age Estimate
Post-production rough-sawn lumber; minimal oxidation suggests it is relatively fresh stock, likely less than 2-5 years old in its current kiln-dried state.
Sustainability Status
Not CITES listed or on the IUCN Red List. Widely available and generally sustainable, though slow-growing; FSC certified stocks are common.
Workability
Excellent workability with both hand and machine tools. Planes and glues well. Can occasionally have tearout in areas of figured grain, but generally takes a very smooth finish.
Notable Features
Distinctive mild, spicy scent when being worked. Known for its shock resistance and dimensional stability once seasoned.
Finish Recommendations
Best suited for clear finishes to highlight color; penetrating oils (like Danish or Tung oil) enhance grain depth, while shellac and lacquer are traditional favorites.
Identification Confidence
High; the characteristic chocolate-brown hue, medium-pore structure, and specific cathedral grain pattern are quintessential markers of Juglans nigra.
