AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Modern cut, likely kiln-dried and recently surfaced. The lack of deep oxidation suggests it has not been exposed to UV for a long duration.
Common Uses
Exterior joinery, boat building, flooring, furniture, cabinetry, and heavy construction.
Geographic Origin
Tropical Africa (West and East Africa)
Workability
Generally works well, but interlocked grain can cause tearout during planing. Contains calcium carbonate deposits (stone) which can dull cutters rapidly.
Finish Recommendations
Takes stains and finishes well. Due to its oily nature and large pores, a grain filler is recommended for a smooth finish, and polyurethane or oils work best for outdoor use.
Notable Features
Often referred to as African Teak though unrelated to Tectona grandis. It has a faint, pleasant scent and the dust can be a sensitizer/irritant to some woodworkers.
