Likely Black Walnut; other brown hardwoods cannot be ruled out from this rough block.

Grain Pattern
Mostly straight to mildly irregular, with broad flat-sawn-looking face grain; rough-sawn surfaces obscure finer figure. No clear decorative figure is visible.
Color & Appearance
Medium to dark brown heartwood with lighter tan-brown areas; sapwood is not clearly distinguishable. Oxidation and finish can deepen the color, while sunlight may lighten it.
Hardness (Janka)
1,010 lbf — Medium
Durability & Decay Resistance
Moderately durable; heartwood has some decay resistance, but is not reliably weather- or insect-proof.
Value & Age
Roughly $8–$20 per board foot for common lumber; figured or unusually large stock may cost more. Species and grade are unverified.
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 estimated from this rough, unfinished block; visible surface wear alone does not establish age.
Common Uses
Furniture, cabinetry, flooring, gunstocks, veneer, turning, and interior trim.
Geographic Origin
Eastern North America, especially the central and eastern United States.
Workability
Generally machines, sands, and glues well; sharp tools help limit tearout on irregular grain. Pre-drilling is useful near edges when fastening.
Finish Recommendations
Sand progressively and apply oil, shellac, lacquer, or clear polyurethane; test on an inconspicuous area because color and absorption may vary.
Notable Features
Walnut commonly has attractive brown heartwood and good dimensional stability; this sample’s rough, stained surfaces prevent confirming characteristic color or figure.
