White Oak
Quercus alba • Hardwood
Grain Pattern
Principally straight grain with a coarse, uneven texture. The sample shows a flat-sawn or plain-sawn cathedral figure near the knot, transitioning into tighter, vertical grain. No significant ray fleck is visible on this face, indicating it is not quarter-sawn.
Color Description
Heartwood is light to medium brown, commonly with an olive cast. Sapwood is slightly lighter. The sample displays an ashy, muted tone typical of raw, unfinished white oak that has oxidized slightly. Over time, it will shift toward a deeper golden amber.
Hardness Rating
1,360 lbf (Hard)
Durability Rating
Very Durable. Highly resistant to rot and decay due to the presence of tyloses that plug the vascular vessels, making it nearly liquid-impermeable.
Common Uses
Furniture, flooring, cabinetry, boatbuilding, barrels (cooperage), interior trim, and heavy construction.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$6.00 - $10.00 per board foot depending on grade and thickness.
Wood Age Estimate
Modern stock. Surface oxidation and the presence of rough-cut edges suggest it is likely seasoned shop lumber, approximately 1-5 years post-harvest, but showing surface dust and grime from storage.
Sustainability Status
Not listed in the CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable with FSC certification common.
Workability
Generally easy to work with machine and hand tools. It has a tendency to react with iron (leaving blue/black stains) due to high tannin content. Responds well to steam bending. Pre-drilling is recommended for screws.
Notable Features
Distinctive tannic scent when cut. High tannin content makes it susceptible to chemical staining. Excellent strength and rot resistance compared to Red Oak.
Finish Recommendations
Takes stains and finishes well. Polyurethane or oil-based finishes are standard for durability. If high tannin content is a concern with water-based finishes, a sealer coat of shellac is recommended to prevent 'tannin bleed.'
Identification Confidence
High; the visible pore structure, color with olive undertones, and specific cathedral grain pattern are classic diagnostic features of North American White Oak.
