Black Walnut (Sapwood)
Juglans nigra • Hardwood
Grain Pattern
Straight to slightly irregular; flat-sawn displaying subtle cathedral peaks and fine, uniform texture with distinct growth rings.
Color Description
Pale yellowish-white to creamy tan sapwood. It lacks the dark chocolate tones of characteristic walnut heartwood but will yellow slightly with UV exposure and age.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Slightly Durable; while walnut heartwood is very durable, the sapwood shown here is susceptible to rot and insect attack if not treated.
Common Uses
Furniture, cabinetry, interior trim, paneling, turned objects, and veneer.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$4.00 - $6.00 per board foot (Sapwood/lower grade is generally cheaper than heartwood select).
Wood Age Estimate
Recently milled (under 1 year); shows no significant oxidation, graying, or tool marks suggesting salvage or historical age.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally sustainable in its native range.
Workability
Excellent workability with both hand and machine tools. It planes smoothly, glues well, and holds screws excellently, though sapwood can sometimes be softer/fuzzier than heartwood.
Notable Features
Faint, mild odor when worked. Walnut is known for being a sensitizer, though sapwood contains fewer extractives than heartwood.
Finish Recommendations
Clear polyurethane or lacquer to maintain the light color, or a penetrating oil to enhance grain depth. It takes stains well if color matching to heartwood is desired.
Identification Confidence
High; the pore structure, color transition, and grain spacing are classic indicators of Juglans nigra sapwood, likely a peripheral cut from a larger log.
