Black Walnut Blocks

Color/Appearance: Heartwood can range from a lighter pale brown to a dark chocolate brown with darker brown streaks. Color can sometimes have a grey, purple, or reddish cast. Sapwood is pale yellow-gray to nearly white. Figured grain patterns such as curl, crotch, and burl are also seen.

Grain/Texture: Grain is usually straight, but can be irregular. Has a medium texture and moderate natural luster.

Rot Resistance: Black walnut is rated as very durable in terms of decay resistance, though it is susceptible to insect attack.

Workability: Typically easy to work provided the grain is straight and regular. Planer tearout can sometimes be a problem when surfacing pieces with irregular or figured grain. Glues, stains, and finishes well (though walnut is rarely stained). Responds well to steam bending.
