Hardness (Janka)

1010 lbf (Medium)

Durability & Decay Resistance

Moderately Durable to Durable, with good resistance to rot though susceptible to insect attack in the sapwood.

Value & Sustainability

Estimated Market Value
6.00 to 12.00 USD per board foot depending on grade and width
Wood Age Estimate
Estimated to be moderately aged, likely between 10 to 30 years based on surface oxidation and mild patina development.
Sustainability Status
Not listed on CITES appendices, IUCN Red List status is Least Concern, widely available domestically from sustainable North American forests.

Common Uses

Fine furniture, cabinetry, architectural millwork, gunstocks, interior paneling, and carving.

Geographic Origin

Eastern North America

Workability

Exceptional workability with both hand and machine tools. Glues, stains, and finishes very well, though care must be taken during planing to avoid tearout on irregular grain figures.

Finish Recommendations

Takes oil finishes, shellac, varnish, and lacquer exceptionally well. Hand-rubbed oil finishes particularly enhance the deep chatoyance and rich color tones.

Notable Features

Possesses a rich natural luster, stable dimensional properties once dried, and a pleasant, mild natural scent when freshly cut.
