Common Uses
Furniture, cabinetry, flooring, veneers, gunstocks, turning, and decorative panels.
Geographic Origin
Eastern and central North America; black walnut is especially associated with the eastern United States.
Workability
Generally machines, sands, and glues well; sharp tools help prevent tearout around knots and irregular grain. Pre-drilling is useful near edges.
Finish Recommendations
Sand evenly and apply oil, shellac, lacquer, or polyurethane; a clear finish preserves the color, while test patches reveal color shifts.
Notable Features
Distinctive brown-and-olive coloration and knot figure; walnut is comparatively stable and commonly used for fine furniture.
