Workability
Excellent workability with both hand and machine tools. Glues, stains, and finishes very well, though deep grain may require filling for a glass-smooth finish
Notable Features
Distinctive mild, spicy odor when worked. Contains juglone, which can be an irritant to some. Known for its exceptional dimensional stability
Finish Recommendations
Penetrating oils or wipe-on polyurethanes are recommended to highlight the natural dark tones and chatoyance without obscuring the grain
Identification Confidence
High; the characteristic chocolate-brown color, pore structure, and specific checking pattern are diagnostic for Juglans nigra
