Grain Pattern
Mostly straight, with pronounced irregular swirling and a knot/crotch-like figure near the center; likely flat-sawn. End grain is not visible, so cut orientation and species are uncertain.
Color & Appearance
Muted gray-brown to brown with darker streaks and lighter areas, possibly weathered or oxidized. Walnut commonly darkens with age, though surface exposure can gray it.
Hardness (Janka)
1,010 lbf — Medium (black walnut).
Durability & Decay Resistance
Moderately durable; heartwood has useful decay resistance, while sapwood is more vulnerable to insects and rot.
Value & Age
Approximately US$8–18 per board foot for ordinary kiln-dried walnut; grade, thickness, and local market strongly 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
- Cannot reliably estimate from this image; gray patina suggests exposure or surface aging, not a specific age.
Common Uses
Furniture, cabinetry, flooring, veneer, carving, turning, and gunstocks.
Geographic Origin
Black walnut is native to eastern and central North America.
Workability
Generally machines and finishes well; figure may cause tearout, so use sharp cutters and light planing cuts. Glues and fastens readily.
Finish Recommendations
Sand evenly and apply oil, shellac, lacquer, or clear polyurethane; a clear finish can deepen the brown tones. Test first, since weathered surface may need sanding back.
Notable Features
Walnut is valued for its rich color and decorative figure; the visible knot and swirling grain add character.
