Common Uses
Furniture, cabinetry, flooring, veneer, turning, and decorative panels.
Geographic Origin
Eastern and central North America, especially the eastern United States.
Workability
Generally works well with hand and machine tools, sands and glues readily, and holds fasteners well. Check for knots and irregular grain that may tear out during planing.
Finish Recommendations
Sand evenly and apply oil, shellac, lacquer, or clear polyurethane; a clear finish can deepen the contrast. Test first, as the apparent surface weathering may affect color absorption.
Notable Features
Distinctive dark streaking and contrasting pale areas; walnut is valued for its color and decorative grain.
