Grain Pattern
Bowl turned from a cross-section or crotch-like blank, showing broad curved growth rings and irregular swirling grain; no clear figured burl is visible.
Color & Appearance
Rich reddish-brown heartwood contrasts sharply with cream-to-pale sapwood. The surface is polished; walnut typically darkens and mellows with age and light.
Hardness (Janka)
1,010 lbf; Medium (Janka), if black walnut.
Durability & Decay Resistance
Moderately Durable; heartwood has useful decay resistance, while sapwood is more vulnerable to insects and rot.
Value & Age
Roughly US$8–20 per board foot for ordinary kiln-dried black walnut; figured or unusually wide stock can cost more. A finished bowl’s value depends on size and workmanship.
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 the image; the polished finish and visible patina do not establish the age of the wood.
Common Uses
Furniture, cabinetry, turned bowls, veneer, flooring, gunstocks, and musical instruments.
Geographic Origin
Black walnut is native to eastern and central North America.
Workability
Generally machines, turns, sands, and glues well. Sharp tools help produce a clean surface; finish exposed end grain evenly to reduce blotching.
Finish Recommendations
Use a clear oil, shellac, lacquer, or polyurethane; test first, as finishes deepen the brown color and emphasize the sapwood contrast.
Notable Features
The dramatic pale sapwood against dark heartwood is the defining visual feature; walnut also has a mild, characteristic scent when freshly cut.
