Value & Sustainability
- Estimated Market Value
- 8.00 to 15.00 USD per board foot for standard lumber, significantly higher for figured crotch or burl turning blanks.
- Wood Age Estimate
- Estimated to be several decades old based on the deep rich patina, oxidation, and stable dried character of the turned bowl.
- Sustainability Status
- Least concern on the IUCN Red List; widely available domestically in North America with good sustainable management.
Common Uses
Fine furniture, cabinetry, turned objects, bowls, gunstocks, interior millwork, and veneer.
Geographic Origin
Eastern North America
Workability
Excellent workability with both hand and machine tools; glues, stains, and finishes exceptionally well, though care must be taken with figured areas to prevent tearout.
Finish Recommendations
Takes oil finishes, shellac, lacquer, and polyurethane wonderfully; a hand-rubbed oil or wax finish highlights the rich depth and chatoyance of the grain.
Notable Features
Contains natural juglone compound which can act as a natural herbicide; highly valued for its exceptional stability, shock resistance, and rich dark coloration.
