Market Value & Sustainability
Estimated Market Value

Workability
Excellent workability with both hand and machine tools; glues, stains, and finishes well. Can occasionally produce tearout in figured areas

Distinctive mild, spicy scent when worked. Known for excellent dimensional stability and shock resistance. Dust can be an irritant to some users
Finish Recommendations
Best suited for penetrating oils (tung or linseed) or clear polyurethane to highlight natural color without staining. Shellac is an excellent sealer
