Black Walnut (Sapwood)
Juglans nigra • Hardwood
Grain Pattern
Mostly straight with fine, even texture. Shows slight cathedral figure transition near the top and a live edge with dark heartwood transition at the far left.
Color Description
Predominantly creamy white to pale yellow sapwood with distinct streaks of greyish-brown heartwood. The wood exhibits a moderate natural luster and will typically yellow slightly with age.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
The heartwood is Very Durable; however, this sapwood portion is Non-durable and susceptible to insect attack and decay if exposed to moisture.
Common Uses
High-end furniture, cabinetry, interior trim, veneer, and specialty turned objects.
Geographic Origin
Eastern United States and parts of Southern Canada.
Market Value & Sustainability
Estimated Market Value
$4.00 - $7.00 per board foot (sapwood-heavy walnut is typically valued lower than all-heartwood boards).
Wood Age Estimate
Relatively fresh milled stock (less than 1-2 years since processing) based on limited oxidation and the clean, light color of the sapwood face.
Sustainability Status
Not listed on CITES Appendices or the IUCN Red List; widely available and generally considered sustainable with FSC options available.
Workability
Excellent workability with both hand and machine tools. Glues, stains, and finishes very well, though sapwood requires careful color matching if used with heartwood.
Notable Features
Distinctive mild, spicy odor when worked. Known for excellent dimensional stability and shock resistance.
Finish Recommendations
Danish oil or clear polyurethane to highlight the natural contrast. Use a sanding sealer if staining to prevent blotching in the sapwood.
Identification Confidence
High; the characteristic transition between the dark chocolate heartwood and creamy sapwood, combined with the grain pore structure, is diagnostic for Juglans nigra.
