Grain Pattern
End grain shows diffuse-looking pores and distinct growth rings; face-grain figure cannot be assessed from this cross-section. No decorative figure is visible.
Color & Appearance
Dark brown heartwood with a broad, pale cream-tan sapwood band; freshly cut surfaces may darken and mellow with oxidation and light exposure.
Hardness (Janka)
1,010 lbf — Medium, near the upper end of the range.
Durability & Decay Resistance
Moderately Durable; heartwood resists decay better than sapwood, which is more vulnerable to insects and rot.
Value & Age
Roughly US$8–$20 per board foot for common kiln-dried lumber; grade, dimensions, and region substantially affect price.
AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Not reliably estimable from this freshly exposed end grain; the visible color is not sufficient to establish age.
Common Uses
Furniture, cabinetry, flooring, veneer, gunstocks, turning, and carving.
Geographic Origin
Black walnut is native to eastern and central North America, especially the eastern United States.
Workability
Generally machines and finishes well; sharp tools help limit tearout, and predrilling is useful near edges. Glues readily.
Finish Recommendations
Sand progressively and apply oil, shellac, lacquer, or clear polyurethane; clear finishes deepen the heartwood color and preserve contrast.
Notable Features
Strong heartwood–sapwood contrast; walnut heartwood often has a mild, distinctive odor when freshly worked.
