White Oak
Quercus alba • Hardwood
Grain Pattern
Predominantly straight to slightly wavy grain with a medium-to-coarse texture. Visible cathedral patterns and some interlocking near knots. Notable presence of large, prominent rays characteristic of the Quercus genus.
Color Description
Light to medium brown heartwood with an olive-colored cast. Sapwood is slightly lighter. Exhibits low to medium luster and typically darkens slightly with age to a golden-brown patina.
Hardness Rating
1,360 lbf (Hard)
Durability Rating
Very Durable. Excellent decay resistance; heartwood is highly resistant to rot. Frequently used for outdoor applications and boatbuilding due to its closed tyloses which prevent water absorption.
Common Uses
Furniture, flooring, cabinetry, boatbuilding, barrels (cooperage), trim, and tool handles.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$6.00 - $9.00 per board foot depending on grade and region.
Wood Age Estimate
The sample appears to be modern rough-sawn lumber, likely air or kiln dried within the last 2-5 years. Visible planer/saw marks and minor surface oxidation suggest it is not newly cut but has been stored in a shop environment.
Sustainability Status
Not listed in the CITES Appendices or on the IUCN Red List of Threatened Species. Generally considered highly sustainable and widely available.
Workability
Generally works well with both hand and machine tools, though it has a high shrinkage rate. Responds well to steam bending. Due to high tannin content, it can react with iron fasteners causing blue/black staining.
Notable Features
Distinctive 'oaky' scent when being worked. High tannin content makes it suitable for fuming with ammonia. Contains tyloses in the pores that make the wood nearly impervious to liquids.
Finish Recommendations
Takes stains and finishes well. Penetrating oils (tung or linseed) highlight the grain, while polyurethane provides superior protection for flooring. Avoid water-based finishes without a sealer to prevent tannin pull.
Identification Confidence
High. The visible pore structure, distinct ray flecks, tan-to-olive color cast, and the specific way 'checks' or cracks appear around the knots are classic diagnostic features of White Oak.
