Common Uses
Furniture, cabinetry, veneer, flooring, gunstocks, turning, and musical instruments.
Geographic Origin
Black walnut is native to eastern and central North America and is also grown in plantations.
Workability
Generally machines, sands, and glues well; sharp tools help limit tearout around irregular grain. Pre-drilling is advisable near edges.
Finish Recommendations
Sand progressively and apply oil, shellac, lacquer, or clear polyurethane. A clear finish deepens the brown; test first because color may vary across the board.
Notable Features
Walnut is moderately heavy, has a mild characteristic scent when worked, and can show attractive dark heartwood and figure; this sample appears rough and ungraded.
