Market Value & Sustainability
Estimated Market Value
$12.00 - $18.00 per board foot for select grade
Wood Age Estimate
Based on the modern joinery styles and the uniform low-luster satin finish, the piece is likely 5-20 years old. The patina shows light oxidation typical of contemporary seasoned walnut.
Sustainability Status
Not listed on CITES Appendices or the IUCN Red List; widely available and generally considered sustainable with FSC certification common.
Workability
Excellent workability with both hand and machine tools. It planes well, glues efficiently, and takes stains and finishes remarkably well, though the dust can be an irritant.
Notable Features
Distinctive mild, spicy scent when worked. Contains juglone, which can be toxic to some plants and horses. Renowned for its dimensional stability after seasoning.
Finish Recommendations
Oil-based finishes (tung or linseed) or clear lacquers to enhance natural color. Polyurethane is recommended for high-wear surfaces like this table leg.
Identification Confidence
High; the open-grain pore structure, specific chocolate-brown hue, and the way the wood reflects light are definitive characteristics of American Black Walnut used in modern furniture.
