Juglans nigra • Hardwood
Grain Pattern
Principally straight but transitioning to a wavy, cathedral figure in this veneer cut. Features semi-porous texture with visible vessel lines.
Color Description
Medium to dark chocolate brown heartwood with some purplish undertones and reddish hints. Sapwood is typically creamy white (not visible here). It tends to lighten/yellow over time with UV exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable; highly resistant to heartwood decay, though susceptible to insect attack (powderpost beetles).
Common Uses
Fine furniture, cabinetry, piano casings, veneers, gunstocks, turned objects, and interior trim.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$10.00 – $15.00 per board foot for solid lumber; veneer costs vary by thickness and figure.
Wood Age Estimate
40–70 years based on the oxidation of the finish, the fine crackle in the lacquer, and typical production eras for this style of piano veneer.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable, including FSC certified options.
Workability
Excellent workability with both hand and machine tools. Glues, stains, and finishes very well. Can occasionally exhibit surface tearout if the grain is irregular.
Notable Features
Distinctive mild, spicy scent when worked. Known for excellent dimensional stability and shock resistance.
Finish Recommendations
High-gloss nitrocellulose lacquer (standard for pianos), polyurethane, or Danish oil to enhance the deep chatoyance of the grain.
Identification Confidence
High; the deep chocolate tones, specific pore structure, and 'piano veneer' context are classic indicators of North American Black Walnut.
