Quercus robur · Hardwood
- Type
- Hardwood
- Origin
- Europe and Asia Minor
- Hardness
- 1,120 lbf (Medium-Hard)
- Durability
- Durable; very resistant to decay and rot due to high tannin content and tyloses in the heartwood pores which prevent liquid penetration.

Grain Pattern
Ring-porous with prominent large earlywood pores; shows a straight to irregular grain. The end grain exhibits distinct medullary rays (radial lines) typical of oak species.
Color & Appearance
Medium tan to light brown heartwood with a grayish cast due to oxidation. Sapwood is typically narrower and lighter. It darkens to a deep golden brown with age and exposure to UV.
Hardness (Janka)
1,120 lbf (Medium-Hard)
Durability & Decay Resistance
Durable; very resistant to decay and rot due to high tannin content and tyloses in the heartwood pores which prevent liquid penetration.
Value & Sustainability
- Estimated Market Value
- $8.00 - $15.00 per board foot for air-dried or reclaimed timber, depending on width and quality.
- Wood Age Estimate
- Estimated 50-100+ years since harvest. The deep oxidation, checking, and rough-cut texture suggest reclaimed timber from an old structure or long-term seasoning.
- Sustainability Status
- Least Concern (IUCN); widely available with FSC certification; highly sustainable in European forestry.
Common Uses
Timber framing, furniture, flooring, cabinetry, boat building, and exterior joinery.
Geographic Origin
Europe and Asia Minor
Workability
Generally good with hand and machine tools, though it has a high blunting effect on edges. Responds well to steam bending. Gluing is satisfactory, but contact with iron can cause blue-black staining.
Finish Recommendations
Penetrating oils (tung or linseed) to highlight natural grain. For architectural use, a matte polyurethane or wax is recommended. Avoid iron-based stains unless a blackened effect is desired.
Notable Features
Distinctive acidic scent when freshly cut. High tannin content can cause corrosion in steel fasteners. Presence of tyloses makes it suitable for liquid-tight applications.
