Value & Sustainability

Estimated Market Value
3.00 to 6.00 USD per board foot
Wood Age Estimate
Mid-20th century (approximately 50-70 years old), indicated by the rich patina, wear patterns, and typical construction style of vintage American Windsor-style chairs.
Sustainability Status
Least Concern, widely abundant and not listed on CITES appendices or the IUCN Red List.

Common Uses

Furniture, cabinetry, veneer, interior trim, and plywood.

Geographic Origin

Eastern North America, ranging from Connecticut down to Florida, and stretching west to Texas.

Workability

Moderately difficult to work with due to interlocked grain which can tear out during planing. Glues, stains, and finishes well when properly prepared.

Finish Recommendations

Takes stains, lacquers, and varnishes exceptionally well. A tinted lacquer or wiping varnish enhances the rich, swirled grain patterns typical of this wood.

Notable Features

Features a distinctive figured grain pattern often marketed as satinwood or stained to mimic walnut; the tree produces a fragrant resin called storax.
