White Oak
Quercus alba • Hardwood
Grain Pattern
Straight and coarse grain, showing prominent medullary rays and large, open pores typical of the ring-porous structure visible on the cross-section
Color Description
Heartwood is light to medium brown, often with an olive cast. Sapwood is light tan to nearly white. This weathered sample shows significant graying (patina) and dark staining from moisture/tannin reaction
Hardness Rating
1,360 lbf (Hard)
Durability Rating
Very Durable; heartwood is highly resistant to decay and rot due to tyloses in the pores, which restrict moisture absorption
Common Uses
Flooring, furniture, cabinetry, boatbuilding, barrel making (cooperage), and heavy construction
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$6.00 - $12.00 per board foot (lumber grade), though this specific firewood sample has low commercial lumber value
Wood Age Estimate
The sample appears to be logs/firewood aged 2-5 years post-cut, evidenced by significant checking (radial cracks), oxidation, and lichen growth on the bark
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable
Workability
Relatively easy to work with machine and hand tools, though it has a high shrinkage rate. Responds well to steam bending. Glues and finishes well
Notable Features
Contains high tannin content which can react with iron to create black stains; distinctive 'whiskey barrel' scent when freshly cut; presence of tyloses makes it uniquely water-tight
Finish Recommendations
Penetrating oils or polyurethane to highlight grain. If the weathered look is desired, a clear sealer is sufficient. Sanding is required to remove the surface oxidation/graying
Identification Confidence
High; the visible medullary rays, ring-porous structure on the end grain, thick bark with lichen, and characteristic radial checking are diagnostic of White Oak
