Value & Sustainability
- Estimated Market Value
- $10.00 - $15.00 per board foot for 4/4 select grade lumber.
- Wood Age Estimate
- Estimated between 50-80 years old, evidenced by the oxidized patina of the wood, wear around the knobs, and the specific style of the incised leaf carvings common in mid-20th century traditional furniture.
- Sustainability Status
- Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable in North America.
Common Uses
High-end furniture, cabinetry, interior trim, gunstocks, veneer, and turned objects.
Geographic Origin
Eastern and Central United States and Southern Ontario, Canada.
Workability
Excellent workability with both hand and machine tools; glues, stains, and finishes very well. Can occasionally experience tearout on irregular grain, but sands to a very smooth luster.
Finish Recommendations
Traditional lacquer or shellac was likely used here. For restoration, a high-quality oil-based polyurethane or wiping varnish would enhance the depth and protect the aging patina.
Notable Features
Distinctive mild, spicy scent when worked. Known for its excellent dimensional stability and shock resistance. Fine pores are visible in the face grain.
