White Oak
Quercus alba • Hardwood
Grain Pattern
Strong, coarse grain with large, open pores. It displays a prominent straight grain with localized irregular patterns and knots. In quarter-sawn sections, it would show distinctive ray fleck patterns.
Color Description
Heartwood is light to medium brown, commonly with an olive cast. Sapwood is slightly lighter. This sample shows surface oxidation and weathering, resulting in a muted, grayish-tan appearance with darkened areas near the knot.
Hardness Rating
1,360 lbf (Hard)
Durability Rating
Very Durable; excellent resistance to rot and decay due to tyloses in the heartwood which plug the vessels, making it liquid-tight and highly resistant to insects.
Common Uses
Cabinetry, furniture, interior trim, flooring, boatbuilding, barrels (cooperage), and heavy construction.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$6.00 to $12.00 per board foot depending on grade and width.
Wood Age Estimate
The sample appears to be seasoned reclaimed lumber or rough-cut stock, likely aged 10-20 years since milling based on the surface oxidation, staining, and dry fiber separation.
Sustainability Status
Abundant and sustainable; not listed in CITES appendices or on the IUCN Red List; widely available with FSC certification.
Workability
Produces good results with hand and machine tools. It has a moderately high shrinkage rate, so dimensional stability is a factor. It glues, stains, and finishes well, though it can react with iron-based fasteners (turning blue/black).
Notable Features
Distinctive tannic smell when wet; contains high tannin content which reacts with iron; high density and strength-to-weight ratio.
Finish Recommendations
Oil-based finishes highlight the grain beauty. Polyurethane or lacquer are recommended for durable protection. Sanding to 220 grit is necessary to manage the coarse texture.
Identification Confidence
High; the pore structure, color tone, and the specific way the wood fibers break around the knot are characteristic of the Quercus genus, specifically the white oak group.
