Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$12.00 - $25.00 per board foot depending on figure intensity
Wood Age Estimate
The finished bowl appears to be 10-30 years old based on the warm amber patina of the finish and slight darkening of the grain.
Sustainability Status
Not listed on CITES Appendices or the IUCN Red List; widely available and generally considered sustainable within its native range.
Workability
Excellent workability with both hand and machine tools; turns very well on a lathe. Can experience some tearout in figured sections, but sands to a very high luster.
Notable Features
Distinctive mild, spicy scent when worked. Known for its excellent dimensional stability and shock resistance.
Finish Recommendations
Food-grade mineral oil or beeswax for kitchen use; tung oil or polyurethane for decorative display to enhance the natural chatoyancy.
Identification Confidence
Medium-High; the grain swirl, color of the 'lighter' walnut varieties common in turnery, and the specific tight knots are characteristic of Juglans nigra juice-wood or crotch grain.
