Market Value & Sustainability
Estimated Market Value
$15.00 - $45.00 per board foot for high-figure veneer or specialty slabs.
Wood Age Estimate
Vintage (50-80 years), indicated by the oxidation of the finish, localized scuffing at the base, and the style of the carved ornamental molding.
Sustainability Status
Generally sustainable; not CITES listed. Classified as Least Concern by the IUCN, though high-quality old-growth burls are becoming scarcer.
Workability
Generally works well with tools, though the highly figured burl sections are prone to significant tearout during planing and routing.
Notable Features
Distinctive mild spicy scent when worked. Known for excellent dimensional stability and exceptional staining/finishing properties.
Finish Recommendations
High-quality lacquer or hand-rubbed oil (like Tung or Danish oil) to accentuate the deep figure and chatoyance.
Identification Confidence
High; the 'topographic' grain lines combined with the deep chocolate-amber hues and the specific style of the figured veneer are classic hallmarks of Black Walnut burl.
