- Hardwood; apparently reclaimed slab
- Origin

Grain Pattern
Broad, mostly straight-to-irregular grain with possible flat-sawn figure; knots, checks, and damaged edges obscure the pattern. End grain is not clearly visible.
Color & Appearance
Weathered gray-brown surface, possibly oxidized walnut; fresh exposed area appears pale tan, so the original heartwood and sapwood colors cannot be reliably judged. Luster and aging response are indeterminate.
Hardness (Janka)
About 1,010 lbf; Medium (if black walnut).
Durability & Decay Resistance
Moderately Durable; walnut heartwood has some decay resistance but is not highly weather- or insect-resistant.
Value & Age
Roughly $8–$20 per board foot for typical walnut lumber; slab price varies greatly with dimensions, figure, condition, and provenance.
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 estimate from appearance alone; surface weathering and wear do not establish the wood’s age.
Common Uses
Furniture, cabinetry, veneer, flooring, turning, and decorative slabs.
Geographic Origin
Black walnut is native to eastern and central North America.
Workability
Generally machines and sands well, though checks, knots, and embedded debris can cause tearout or tool damage. Pre-drilling is advisable near edges; glue and finishes typically perform well on clean, sound wood.
Finish Recommendations
Clean and inspect first, remove loose debris, and test a finish on fresh wood. Oil or clear varnish can enhance walnut’s color; stabilize or fill checks as desired.
Notable Features
The slab has irregular edges, checks, knots, and numerous small holes; these may reflect prior use or insect damage, but are not species-diagnostic.
