Grain Pattern
Flat-sawn end grain with prominent, diffuse earlywood pores and relatively straight grain. The central rose-like figure is unusual—likely spalting, woundwood, or fungal staining rather than normal figure.
Color & Appearance
Pale tan to light brown sapwood/wood with pink, burgundy, and gray localized discoloration; red oak often darkens modestly amber-brown with light exposure.
Hardness (Janka)
Janka about 1,290 lbf — Hard.
Durability & Decay Resistance
Slightly durable; heartwood has limited decay resistance and is not ideal for prolonged exterior exposure.
Value & Age
Approximately US$3–8 per board foot for ordinary kiln-dried lumber; figured or specialty slabs may be higher.
AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Freshly cut or recently exposed round; the discoloration indicates tree history, not necessarily old age. Sample age cannot be estimated reliably from this photograph.
Common Uses
Furniture, flooring, cabinetry, millwork, veneer, interior trim, pallets, and general construction.
Geographic Origin
Eastern and central North America, especially the Great Lakes, Appalachians, and northeastern United States and Canada.
Workability
Machines and sands well, though open pores and interlocked grain can cause tearout; glues and fastens readily. End-grain checking is possible during drying.
Finish Recommendations
Sand progressively and seal end grain; oil, shellac, lacquer, or polyurethane are suitable. Grain filler can produce a smoother finish.
Notable Features
Distinctive ring-porous end grain and pink-purple central staining, probably associated with a wound, branch base, or fungal activity.
