American black walnut is one of the most prized North American hardwoods, valued for its rich colour, straight grain, and excellent workability. The heartwood ranges from a warm chocolate brown to a dark, almost purplish-black, often with streaks of lighter or darker colour.
Working properties
Walnut works well with both hand and machine tools. It planes cleanly, turns beautifully, and carves with remarkable ease for its hardness. The open pores take oil finishes and stains evenly, though the natural colour is so attractive that many woodworkers prefer a clear finish.
Gluing is straightforward; walnut accepts wood glue reliably across all joint types.
Typical applications
- Fine furniture and heirloom pieces
- Cabinet doors, face frames, and drawer fronts
- Rifle and shotgun stocks (classic choice since the 18th century)
- Turned bowls, pens, and decorative objects
- Hardwood flooring (moderately priced)
Notes
Sapwood is dramatically lighter than the heartwood and is generally considered undesirable for furniture work — most craftsmen cut it away. Steaming freshly cut lumber can darken the sapwood to better match the heartwood colour.
