Not listed in CITES Appendices or on the IUCN Red List; widely available and generally sustainable in North America.
Workability
Excellent workability with both hand and machine tools; glues, stains, and finishes well. It is known for its dimensional stability.
Notable Features
Distinctive mild, spicy scent when being worked; contains juglone which can be an irritant; highly prized for its rich color and finish quality.
Finish Recommendations
Oil-based finishes (tung or linseed) to enhance depth; clear lacquer or polyurethane for durability while maintaining the natural dark hue.
