Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Straight grain with a medium texture; exhibits some cathedral-like characteristics typical of flat-sawn boards. Visible small knots and pores are consistent with walnut.
Color Description
Heartwood is a light to medium brown with a cool grayish cast (likely naturally dried or air-dried rather than steamed); sapwood is pale yellow-gray. Patina tends to mellow to a more golden-brown over time with UV exposure.
Hardness Rating
1,010 lbf (Medium Hardness)
Durability Rating
Durable; very resistant to heartwood decay, though sapwood is susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, luxury flooring, gunstocks, interior trim, veneer, and musical instruments.
Geographic Origin
Eastern United States and parts of Southern Canada.
Market Value & Sustainability
Estimated Market Value
$10.00 – $18.00 per board foot depending on thickness and quality.
Wood Age Estimate
Relatively recent milling; likely 1-3 years old. The lightness suggests it hasn't developed deep library-aged oxidation yet.
Sustainability Status
Highly sustainable; not listed on CITES or IUCN Red List. Widely available from FSC certified sources.
Workability
Excellent workability with both hand and machine tools. Planes well, glues easily, and takes screws/nails without much risk of splitting. Sanding produces a very smooth surface.
Notable Features
Distinctive mild, spicy odor when being worked. Known for its shock resistance and dimensional stability once seasoned.
Finish Recommendations
Penetrating oils or wiping varnishes (like Danish oil or Arm-R-Seal) are recommended to highlight the natural grain without making it look plastic; polyurethane is suitable for high-wear surfaces.
Identification Confidence
High; the pore structure, color tone, and specific distribution of 'eyes' and grain marks are classic indicators for North American Black Walnut.
