Grain Pattern

Prominent cathedral grain on flat-sawn surfaces with visible ray fleck. Texture is coarse and uneven with large open pores typical of ring-porous woods.

Color & Appearance

Medium to dark brown heartwood with a yellowish cast, though the sample appears stained. Natural sapwood is light tan. It exhibits a moderate luster and tends to darken/amber over time with light exposure.

Hardness (Janka)

1,360 lbf (Hard)

Durability & Decay Resistance

Very Durable. High tannin content provides excellent resistance to rot and decay; widely used for moisture-sensitive applications.

Value & Sustainability

Estimated Market Value
$6.00 - $12.00 per board foot depending on grade and width.
Wood Age Estimate
The surface patina, micro-scratching in the finish, and depth of color suggest the installation or finish is approximately 15-30 years old.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable with FSC options.

Common Uses

Flooring, furniture, cabinetry, boat building, barrels (cooperage), and architectural millwork.

Geographic Origin

Eastern North America

Workability

Works well with both hand and machine tools. Responds well to steam bending. Gluing, staining, and finishing are generally easy, though high tannin can react with iron-based fasteners to cause staining.

Finish Recommendations

Polyurethane or oil-based finishes are ideal for flooring. Given the open grain, a grain filler can be used if a glass-smooth surface is desired.

Notable Features

Distinctive 'oak' scent when worked. Contains tyloses in the pores which make the wood nearly water-tight, unlike Red Oak.
