Value & Sustainability

Estimated Market Value
4.00 to 8.00 USD per board foot depending on grade and quarter-sawn percentage.
Wood Age Estimate

Geographic Origin

Eastern North America

Workability

Generally good workability with hand and machine tools, though it can blunt cutting edges due to hardness; glues, stains, and finishes well, but reacts with iron to cause discoloration.

Finish Recommendations

Polyurethane, conversion varnish, or penetrating oils; water-based finishes help preserve the lighter natural color without excessive yellowing.

Notable Features

Contains tyloses in the vessels making it watertight, high tannin content which reacts chemically with iron and steel.
