Geographic Origin

Eastern United States and parts of Southern Canada.

Market Value & Sustainability

Estimated Market Value

$10.00 - $18.00 per board foot depending on figure and width.

Wood Age Estimate

Estimated 40-70 years old based on the oxidation of the grain, the darkened patina of the finish, and the construction style of the paneling.

Sustainability Status

Not listed in CITES Appendices or the IUCN Red List; widely available and generally considered sustainable with FSC options.

Workability

Typically easy to work with both hand and machine tools. It planes well, glues, stains, and finishes exceptionally well, though it has a faint distinct odor when being worked.

Notable Features

Features a mild, spicy scent when worked. Known for its excellent dimensional stability and shock resistance. Can cause allergic reactions in some woodworkers (sensitizer).

Finish Recommendations

Wiping oils (linseed or tung) highlight the depth; polyurethane for durability; or shellac for a traditional period look. This sample appears to have a dark-toned lacquer or varnish.

Identification Confidence

High; the characteristic cathedral grain, dark chocolate pore structure, and the way the wood has oxidized under the finish are classic markers of North American Black Walnut.
