Grain Pattern
Straight but can be irregular or cross-grained; features prominent medullary rays and ring-porous structure visible in cross-section. Distinguishable 'growth rings' are tight and clear.
Color & Appearance
Heartwood is a light to medium brown, often with an olive cast. Sapwood is thin and significantly lighter (pale yellowish-white). Oxidation and exposure have caused the surface to develop a warmer, golden-brown patina.
Hardness (Janka)
1,120 lbf (Medium to Hard)
Durability & Decay Resistance
Very Durable; known for excellent resistance to rot and decay. Highly resistant to insect attack but sapwood is susceptible to powder post beetles.
Value & Sustainability
- Estimated Market Value
- $5.00 to $12.00 per board foot depending on cut (e.g., quarter-sawn values are higher); low value as a raw log stump.
- Wood Age Estimate
- The tree was approximately 40-50 years old based on ring count. The stump itself appears recently cut and processed (1-3 years) with fresh oxidation and light surface Checking/cracking.
- Sustainability Status
- Least Concern on IUCN Red List; widely available and frequently FSC certified. Generally very sustainable.
Common Uses
Landscaping (log seating), heavy construction, ship building, fine furniture, flooring, cabinetry, and wine barrels.
Geographic Origin
Native to most of Europe into Asia Minor and North Africa; naturalized in North America.
Workability
Standard for oak; easy to work with machines but requires sharp tools to prevent tearout. High tannin content can cause blue-black staining if in contact with iron in wet conditions.
Finish Recommendations
Currently unfinished; for outdoor longevity, a penetrating oil (tung or linseed) or an outdoor-rated UV-resistant polyurethane is recommended.
Notable Features
Characteristic 'oaky' scent when freshly cut. High tannin content acts as a natural preservative. Weight is approximately 42 lbs/ft3. Visible 'checking' (cracking) is normal as the log dries.
