- Hardwood
- Origin
- Likely Europe; oak also grows widely across the Northern Hemisphere.

Grain Pattern
Broad, prominent growth rings with mostly straight grain and a knot; the flat-sawn face shows a cathedral-like pattern. End grain is not visible, limiting identification.
Color & Appearance
Weathered tan to medium brown with darker staining around the knot; fresh oak is typically pale tan to brown and darkens with age and light exposure.
Hardness (Janka)
About 1,120 lbf (European oak); Medium under the supplied scale.
Durability & Decay Resistance
Durable heartwood; good rot resistance, while sapwood is less resistant. Insects may attack untreated wood.
Value & Age
Roughly US$5–$12 per board foot for ordinary oak lumber; reclaimed or unusually large stock varies substantially.
AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Cannot reliably determine from the image; weathering and checking indicate outdoor exposure, not a specific age.
Common Uses
Furniture, flooring, cabinetry, framing, beams, barrels, and boatbuilding.
Geographic Origin
Likely Europe; oak also grows widely across the Northern Hemisphere.
Workability
Machines and glues well, though coarse grain can tear out and tannins may react with iron. Pre-drilling helps prevent splitting near edges.
Finish Recommendations
Sand evenly and use oil, shellac, lacquer, or polyurethane; test first, as weathering and tannin staining can affect color.
Notable Features
Visible growth-ring contrast and a knot; oak is heavy and has prominent rays, best confirmed on quartersawn or end-grain surfaces.
