AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- The board’s age cannot be determined visually; it appears recently milled or moderately seasoned, with no reliable antique patina.
Common Uses
Fine furniture, cabinetry, flooring, gunstocks, interior trim, veneer, turning, and decorative slabs.
Geographic Origin
Eastern and central North America, especially the United States and southern Canada.
Workability
Generally machines and sands well, though localized grain reversal and inclusions may cause minor tear-out. Glues, screws, and finishes reliably; use sharp cutters.
Finish Recommendations
Apply a penetrating oil, shellac, lacquer, or clear polyurethane after thorough sanding; a clear finish preserves contrast, while oil deepens the brown color.
Notable Features
Distinctive dark heartwood, attractive contrast, moderate dimensional stability, and occasional mineral streaking or knot inclusions.
