White Oak
Quercus alba • Hardwood
Grain Pattern
Quarter-sawn grain featuring prominent, long medullary rays (flecking). The grain is straight with an open-pored texture and a distinct rippled or corduroy surface texture due to weathering.
Color Description
Medium tan to light brown heartwood with a grayish-white sapwood. This sample shows significant oxidation and silver-gray weathered patina with some darker mineral staining and potential mold spotting in damp areas.
Hardness Rating
1,360 lbf (Hard)
Durability Rating
Durable; excellent resistance to rot and fungal decay due to tyloses in the pores. Highly resistant to water penetration.
Common Uses
Cooperage (wine and whiskey barrels), flooring, cabinetry, heavy construction, boat building, and outdoor furniture.
Geographic Origin
Eastern United States
Market Value & Sustainability
Estimated Market Value
$6.00 - $12.00 per board foot depending on grade and rift/quarter-sawn orientation.
Wood Age Estimate
30-60 years based on the heavy surface oxidation, deep weathering of the ray flecks, and the accumulation of surface grime and patina.
Sustainability Status
Least Concern (IUCN); widely available and generally considered sustainable with FSC certification common.
Workability
Strong and dense; works well with machine tools but has a high dulling effect on cutters. Glues, stains, and finishes well, though large pores may require filling for a smooth surface.
Notable Features
High tannin content can react with iron/steel fasteners to cause black staining. Famous for its liquid-tight properties due to tyloses.
Finish Recommendations
Penetrating oils or film-building polyurethanes. For weathered pieces, thorough sanding to reach fresh wood followed by a UV-inhibiting outdoor finish is recommended.
Identification Confidence
High; the large, distinct medullary rays (ray fleck) shown in the quarter-sawn face are a diagnostic hallmark of the White Oak group.
