Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Straight to slightly irregular with a semi-porous texture and occasional cathedral figure visible on the flat-sawn face shown
Color Description
Heartwood is a medium to dark chocolate brown with visible darker streaks; sapwood is typically pale yellow-gray. Naturally medium luster, it tends to develop a warm honey-colored patina and may lighten slightly over decades of light exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable and very resistant to heartwood decay, though susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, gunstocks, interior paneling, veneer, and turned objects.
Geographic Origin
Eastern United States and parts of Southern Canada
Market Value & Sustainability
Estimated Market Value
Approximately $12.00 to $18.00 per board foot for select grade lumber.
Wood Age Estimate
Estimated 20-50 years based on the deep oxidation, smooth edges, and the classic mid-century style of the furniture component shown.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; generally considered sustainable and widely available from managed forests.
Workability
Excellent workability with both hand and machine tools; glues, stains, and finishes very well. Minimal tearout when working straight grain.
Notable Features
Distinctive mild, spicy scent when worked. High tannin content. Often contains dark 'pith' flecks or streaks that add character.
Finish Recommendations
Penetrating oils or wiping varnishes respond best to highlight the grain depth; polyurethane or lacquer provide excellent protection for high-use items.
Identification Confidence
High; the open-pore structure, specific deep brown hue with characteristic gray undertones, and the application in a furniture leg/arm strongly support Black Walnut.
