Market Value & Sustainability
Estimated Market Value
$12.00 - $18.00 per board foot (depending on figure and grade)

Workability
Generally easy to work with both hand and machine tools. Planes and glues well; takes stains and finishes extremely well, though it is rarely stained
Notable Features
Distinctive mild, spicy odor when being worked. Known for its excellent dimensional stability and shock resistance
Finish Recommendations
Oil-based finishes (like Danish oil or Tung oil) highlight the depth and chatoyance; clear lacquer or polyurethane for heavy-use surfaces
Identification Confidence
High; the chocolate brown hue combined with the diffuse-porous grain structure and texture is characteristic of North American Black Walnut
