Chestnut (Likely American Chestnut)
Castanea dentata • Hardwood / Reclaimed
Grain Pattern
Strongly ring-porous grain with prominent cathedral figure patterns visible through the distress; grain is generally straight but coarse in texture.
Color Description
Heartwood is light to medium brown, darkening to a reddish-brown with age. Sapwood is narrow and pale white/light brown. This sample shows significant oxidation and deep ambering typical of antique stock.
Hardness Rating
540 lbf (Soft)
Durability Rating
Very Durable; characterized by high tannin content providing excellent resistance to rot and decay, though highly susceptible to Powder Post Beetle infestation (visible in sample).
Common Uses
Historically used for cabinetry, furniture, and local construction. Currently found almost exclusively as reclaimed lumber for flooring, rustic furniture, and decorative beams.
Geographic Origin
Eastern North America (formerly dominant from Maine to Mississippi, now largely extinct due to blight).
Market Value & Sustainability
Estimated Market Value
$12.00 to $20.00 per board foot for high-grade reclaimed Wormy Chestnut.
Wood Age Estimate
Estimated 80-120 years old based on the deep oxidation, mechanical wear, and extensive insect exit holes (characteristic of 'Wormy Chestnut').
Sustainability Status
Listed as Critically Endangered by the IUCN; commercially available only as reclaimed wood from historic structures or salvaged dead-standing trees.
Workability
Generally easy to work with hand and machine tools, though it is prone to splitting when nailing. The wood is brittle due to age and tannin content.
Notable Features
Features numerous small insect holes and tracking known as 'wormy' character; high tannin content can react with iron to cause dark staining; distinct lack of ray flecks compared to Oak.
Finish Recommendations
Oil-based finishes or shellac are recommended to highlight the deep patina. Penetrating oils help stabilize the brittle surface of reclaimed boards.
Identification Confidence
Medium-High; the ring-porous structure and classic 'wormy' appearance combined with the lack of visible medullary rays (which would indicate Oak) is highly indicative of American Chestnut.
