- Type
- Hardwood / Reclaimed
- Origin
- Eastern North America (Appalachian Mountains)
- Hardness
- 540 lbf (Soft)
- Durability
- Durable to Very Durable. Highly resistant to rot and decay, though the 'wormy' holes indicate historic insect activity (though the insects are no longer active in dried lumber).

Grain Pattern
Straight to spiral grain with a coarse, uneven texture. Features prominent 'worm holes' caused by beetle larvae, which are characteristic of salvaged blight-killed timber. Flat-sawn appearance with noticeable growth rings and small knots.
Color & Appearance
Heartwood is a light to medium brown, often turning to a reddish or golden brown with age. Sapwood is narrow and off-white to light brown. The sample shows typical oxidation and graying consistent with long-term storage or salvaged status.
Hardness (Janka)
540 lbf (Soft)
Durability & Decay Resistance
Durable to Very Durable. Highly resistant to rot and decay, though the 'wormy' holes indicate historic insect activity (though the insects are no longer active in dried lumber).
Value & Sustainability
- Estimated Market Value
- $12.00 - $20.00 per board foot, depending on the intensity of the wormy character and board width.
- Wood Age Estimate
- 50 to 100+ years. The presence of blight-induced worm holes suggests the wood was harvested from trees killed by the chestnut blight in the early to mid-20th century.
- Sustainability Status
- Listed as Critically Endangered by the IUCN due to the Chestnut Blight. Functional availability is strictly through reclaimed sources or dead-standing salvage; it is not available as new-growth FSC timber.
Common Uses
Rustic furniture, cabinetry, interior trim, flooring, reclaimed barn siding, and decorative picture frames.
Geographic Origin
Eastern North America (Appalachian Mountains)
Workability
Easy to work with both hand and machine tools. It splits easily, so pre-drilling for nails and screws is essential. Glues and finishes well, though the worm holes may require filling if a smooth surface is desired.
Finish Recommendations
Penetrating oils or matte polyurethanes are best to preserve the rustic, reclaimed look. If used for tabletops, a film-building finish or epoxy may be needed to seal the insect holes.
Notable Features
Distinctive pinhole patterns from the chestnut timber worm. It is surprisingly lightweight for a hardwood and has high tannin content, which can cause black staining if it contacts iron in wet conditions.
