White Oak
Quercus alba • Hardwood
Grain Pattern
Ring-porous with prominent large earlywood pores and very small latewood pores. End grain shows visible growth rings; long rays are present but obscured by the rough cross-cut surface. Would typically show cathedral patterns in flat-sawn or medullary rays in quarter-sawn boards.
Color Description
Heartwood is a light to medium brown, often with an olive cast. Sapwood is light tan to nearly white and is not always sharply demarcated from heartwood. Tends to darken slightly with age and UV exposure.
Hardness Rating
1,350 lbf (Hard)
Durability Rating
Very Durable; heartwood is highly resistant to decay and rot due to tyloses in the pores, making it exceptionally waterproof and resistant to fungi.
Common Uses
Cabinetry, furniture, interior trim, flooring, boatbuilding, barrels (cooperage), and tool handles.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$5.00 - $9.00 per board foot depending on grade and width.
Wood Age Estimate
Based on the growth ring count in the cross-section, the limb or trunk is approximately 20-25 years old. The sample appears freshly cut (within 1-6 months) given the lack of significant checking or graying oxidation.
Sustainability Status
Not listed in the CITES Appendices or on the IUCN Red List of Threatened Species; widely available with FSC certification.
Workability
Generally easy to work with machine and hand tools, though it has a high shrinkage rate. Responds well to steam bending. Glues, stains, and finishes well, though pre-drilling for screws is recommended due to its density.
Notable Features
Distinctive tannic scent when worked. High tannin content can cause blue/black staining when in contact with iron in wet conditions. Contains tyloses, which plug the vessels and make the wood impervious to liquids.
Finish Recommendations
Oil-based finishes highlight the grain best. Polyurethane or lacquer provides excellent protection for high-wear surfaces like flooring. Reactive stains (iron acetate) can be used to ebonize the wood due to high tannin content.
Identification Confidence
High; the ring-porous structure, bark texture, olive-brown heartwood hue, and presence of tyloses in the earlywood pores are characteristic of the White Oak group.
