Grain Pattern
Straight to spiraled with coarse texture; distinctive ring-porous grain similar to Oak but without the large conspicuous medullary rays. Frequently features small holes from wood-boring beetles (wormy chestnut).
Color & Appearance
Heartwood is a light to medium brown, often with a reddish or grayish cast. Sapwood is narrow and pale white to light brown. Weathered wood turns a distinct silvery gray; internal wood darkens slightly with age to a rich honey-brown.
Hardness (Janka)
540 lbf (Soft)
Durability & Decay Resistance
Very Durable. Highly resistant to rot and decay, though susceptible to insect attack (specifically powderpost beetles).
Value & Sustainability
- Estimated Market Value
- $15.00 - $30.00 per board foot (primarily sourced as reclaimed lumber due to extinction from chestnut blight).
- Wood Age Estimate
- Live standing tree (Mature). Based on bark fissuring, the tree is likely between 40 to 70 years old, representing a rare surviving or re-sprouted specimen.
- Sustainability Status
- Critically Endangered/Functionally Extinct (IUCN). Use is almost exclusively limited to reclaimed or salvaged material. Harvesting live specimens is strictly regulated.
Common Uses
Historically used for furniture, cabinetry, flooring, fence posts, and construction. Currently primarily used for reclaimed rustic furniture and high-end artisanal woodworking.
Geographic Origin
Eastern North America (Appalachian Mountains and surrounding regions).
Workability
Easy to work with both hand and machine tools. It glues, stains, and finishes well. Due to its softness, it is prone to denting and fine splitting if not pre-drilled.
Finish Recommendations
Responds well to oil-based finishes (Tung or Linseed) which enhance the honey tones. Wax and shellac are excellent for reclaimed pieces to preserve the 'wormy' character.
Notable Features
Famed for its historical importance prior to the Chestnut Blight. Contains high tannin content. Notable for lack of ray fleck compared to Oak. Historically known as the 'Cradle to Grave' wood in the US.
