Market Value & Sustainability
Estimated Market Value
$10.00 to $18.00 per board foot depending on thickness and figuring.
Wood Age Estimate
The visible piece of furniture in the background appears to be an antique/vintage piece, likely 50-80 years old based on the deep patina and traditional dresser construction styles.
Sustainability Status
Not listed in the CITES Appendices or on the IUCN Red List of Threatened Species; widely available and generally sustainable.
Workability
Excellent workability with both hand and machine tools. Planes and glues well; takes finishes exceptionally well. Can have moderate blunting affect on cutters.
Notable Features
Distinctive mild, spicy scent when being worked; high tannin content; known for its stability and dimensional strength.
Finish Recommendations
Oil-based finishes (tung or linseed) are recommended to enhance the natural depth and color. Clear lacquers or polyurethanes also work well.
Identification Confidence
Medium-High. Based on the background furniture (dresser), the dark brown coloration and grain structure are highly characteristic of traditional American Black Walnut craftsmanship.
