Grain Pattern
Broad, irregular flat-sawn grain with prominent growth rings, radial checking, and possible bark inclusion; no clear decorative figure visible
Color & Appearance
Weathered dark brown to gray surface obscures the original chocolate-brown heartwood and pale sapwood; fresh cuts would show stronger contrast and moderate luster
Hardness (Janka)
1,010 lbf Janka — Medium
Durability & Decay Resistance
Moderately Durable; heartwood has useful decay resistance, while exposed weathered sapwood is more vulnerable to rot and insects
Value & Age
Approximately $8–$18 per board foot for sound, usable walnut; this heavily weathered, irregular piece may have much lower practical value
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 be reliably dated from the photograph; surface weathering suggests prolonged outdoor exposure, not necessarily old wood
Common Uses
Furniture, cabinetry, flooring, gunstocks, veneer, turning, and trim
Geographic Origin
Eastern and central North America, especially the Ohio and Mississippi valleys
Workability
Generally machines and sands well, though this slab’s checks, dirt, bark, and irregular grain will cause tear-out and tool wear; predrill fasteners
Finish Recommendations
Remove weathered material, dry and stabilize thoroughly, then use oil, shellac, lacquer, or polyurethane; sanding sealer can reduce uneven absorption
Notable Features
Valuable dark heartwood, attractive color contrast, moderate dimensional stability, and occasional curly or crotch figure
