Grain Pattern

Straight, coarse grain with a flat-sawn cathedral pattern visible. Large open pores are present in the earlywood zone. No significant figure like curl or bird's eye is present, though small medullary ray flecks are characteristic of the species.

Color & Appearance

Light to medium brown heartwood with an olive-colored cast. The sapwood is a paler off-white. This sample shows some surface staining or graying from oxidation and light exposure, which is common as it ages toward a darker amber or gray hue.

Hardness (Janka)

1,350 lbf (Hard)

Durability & Decay Resistance

Very Durable. Excellent resistance to rot and decay due to tyloses in the pores, making it suitable for water-tight applications.

Value & Sustainability

Estimated Market Value
$6.00 - $10.00 per board foot depending on grade and region.
Wood Age Estimate
Based on the oxidation gradient and the rough-sawn surface, this piece appears to be several years old, likely air-dried or salvaged from a secondary project.
Sustainability Status
Highly sustainable; not listed on CITES or IUCN Red List. FSC certification is widely available.

Common Uses

Furniture, flooring, cabinetry, boatbuilding, barrel making (cooperage), interior trim, and heavy construction.

Geographic Origin

Eastern North America

Workability

Excellent results with machine and hand tools. However, it has a high shrinkage rate and can be prone to splintering. It reacts with iron (tannin stain) and holds nails and screws well after pre-drilling.

Finish Recommendations

Takes stains and finishes well. Polyurethane or oil finishes (like Tung or Linseed) are recommended to highlight the grain. Avoid iron-based stains unless a blackened effect is desired.

Notable Features

Distinctive tannic scent when cut. Contains high levels of tannins which can cause dark blue/black staining when in contact with iron and water. High density and weight.
