Juglans nigra • Hardwood
Grain Pattern
Straight grain with subtle wavy figure and a cathedral pattern visible in the flat-sawn section. Medium texture with a semi-porous surface.
Color Description
Heartwood is a light to medium brown with a slight grayish-tan cast; will likely darken or develop a rich honey-brown patina with time and UV exposure. Sapwood is typically pale yellowish-white, though not distinctly prominent in this cut.
Hardness Rating
1010 lbf (Medium Hardness)
Durability Rating
Durable; rated as very resistant to heartwood decay, though susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, veneer, gunstocks, interior trim, and turned objects.
Geographic Origin
Eastern United States and parts of Southern Canada.
Market Value & Sustainability
Estimated Market Value
$10.00 - $15.00 per board foot depending on region and grade.
Wood Age Estimate
Relatively recent/kiln dried; the lack of deep oxidation and the sharpness of the surface indicates a fresh mill cut or modern lumber stock (under 5 years processed).
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable in North America.
Workability
Generally easy to work with both hand and machine tools. It planes well, glues, and finishes excellently. Can occasionally experience fuzzy grain if tools are not sharp.
Notable Features
Distinctive mild, spicy scent when worked. Known for its excellent dimensional stability and shock resistance.
Finish Recommendations
Oil-based finishes (tung or linseed) to enhance natural color and depth, or clear polyurethane/lacquer for durable protection.
Identification Confidence
Medium-High; the tan-brown coloration, pore structure, and characteristic grain swirl are consistent with Juglans nigra, though some lighter Butternut or Teak can look similar in specific lighting.
