White Oak
Quercus alba • Hardwood
Grain Pattern
Straight, coarse grain. The sample shows a quarter-sawn to rift-sawn orientation with visible medullary rays appearing as small vertical flecks. Open-pored texture with a consistent, linear figure.
Color Description
Heartwood is a light to medium brown, commonly with an olive cast. Sapwood is near-white to light brown and not always sharply demarcated from heartwood. This sample shows typical silvery-gray weathering or oxidation consistent with aged raw oak.
Hardness Rating
1,360 lbf (Hard)
Durability Rating
Very Durable; excellent resistance to rot and decay due to the presence of tyloses in the heartwood pores which make the wood nearly liquid-tight.
Common Uses
Furniture, flooring, cabinetry, boat building, barrels (cooperage), interior trim, and heavy construction.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$6.00 - $12.00 per board foot depending on width and grade.
Wood Age Estimate
Estimated 20-50 years since harvest. The surface shows significant oxidation and silvering/graying consistent with salvaged or long-stored lumber rather than freshly milled stock.
Sustainability Status
Abundant and sustainable; classified as Least Concern by the IUCN. Widely available with FSC certification.
Workability
Produces good results with hand and machine tools. Has a moderately high shrinkage rate, so dimensional stability can be an issue. Can react with iron (iron gall ink reaction) causing dark staining if wet.
Notable Features
Distinctive tannic scent when worked. High tannin content makes it ideal for fuming with ammonia to darken the wood. Contains tyloses which block the vascular tubes, making it suitable for water-tight applications.
Finish Recommendations
Takes stains and finishes well. Polyurethane or oil-based finishes are recommended to highlight the medullary rays. If staining, a wood conditioner is rarely needed due to uniform pore distribution.
Identification Confidence
High. The visible large pores, straight grain, medullary ray flecks (flakes), and specific olive-brown hue are definitive characteristics of the White Oak group.
