Market Value & Sustainability
Estimated Market Value
$12.00 - $20.00 per board foot depending on thickness and width
Wood Age Estimate
Estimated 40-70 years based on the deep oxidation of the wood fibers, finish crazing on the stiles, and substantial patina characteristic of vintage cabinetry

Workability
Excellent workability with both hand and machine tools; it planes easily, glues and finishes well, and holds nails and screws securely
Notable Features
Distinctive faint, spicy scent when worked; medium weight with excellent dimensional stability; contains some tannins
Finish Recommendations
Penetrating oils or wiping varnishes are highly recommended to highlight the natural chatoyance and grain depth without obscuring it with thick films
Identification Confidence
High; the characteristic chocolate-brown color, cathedral grain patterns, and specific way the wood has oxidized and accepted stain in the moldings are diagnostic for Juglans nigra
