Black Walnut (Sapwood)
Juglans nigra • Hardwood
Grain Pattern
Mostly straight grain with light cathedral figuring in flat-sawn sections; fine to medium texture
Color Description
Creamy white to pale gray-yellow sapwood with subtle grayish streaks. Unlike the dark chocolate heartwood, this sapwood is light and will yellow slightly with UV exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable (heartwood is very resistant to decay, but sapwood is susceptible to insect attack and rot if untreated)
Common Uses
Furniture, cabinetry, interior trim, flooring, and small specialty wood objects
Geographic Origin
Eastern United States and Southern Ontario, Canada
Market Value & Sustainability
Estimated Market Value
Typically $4.00 - $6.00 per board foot (sapwood is generally valued lower than dark heartwood)
Wood Age Estimate
Relatively fresh lumber (under 2 years); show no significant oxidation or UV-induced darkening
Sustainability Status
FSC available; not CITES listed; classified as Least Concern by IUCN
Workability
Excellent workability with both hand and machine tools; glues, stains, and finishes exceptionally well; easy to plane with minimal tearout
Notable Features
Faint, pleasant spicy scent when worked; sapwood lacks the high tannin content of heartwood but maintains the same density and stability
Finish Recommendations
A clear Danish oil or polyurethane to highlight the pale tones; some woodworkers use a dark stain to match it to walnut heartwood
Identification Confidence
Medium; the pore structure and transition streaks are characteristic of Juglans nigra sapwood, though it can resemble Butternut or light Birch without seeing the heartwood.
