White Oak
Quercus alba • Hardwood
Grain Pattern
Straight grain with a coarse, uneven texture. The end grain shows large, open pores arranged in distinct rings (ring-porous). Face grain displays a mix of flat-sawn cathedral patterns and some rift-sawn characteristic of thick dimensional lumber.
Color Description
Heartwood is a light to medium brown, commonly with an olive cast. Sapwood is near white to light brown. The wood darkens slightly with age to a more amber or tan hue. Some grayish surface oxidation is visible where the wood is rough-cut and aged.
Hardness Rating
1,360 lbf (Hard)
Durability Rating
Very Durable; exceptional resistance to rot and decay due to tyloses in the heartwood pores which make it nearly liquid-impermeable. Good resistance to insects.
Common Uses
Furniture, flooring, cabinetry, boat building, barrels (cooperage), heavy timber framing, and high-end exterior millwork.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$6.00 to $9.00 per board foot depending on width and thickness.
Wood Age Estimate
The rough-sawn lumber shows signs of air drying for 1-2 years, indicated by the surface oxidation, checking at the ends, and 'RO' (Rough Oak) markings.
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, though it has a high shrinkage rate and requires pre-boring for screws. It responds well to steam bending. High tannin content can react with iron fasteners causing blue/black staining.
Notable Features
Tyloses in pores make the wood waterproof; distinct tannic scent when freshly cut. Heavy and strong with excellent shock resistance.
Finish Recommendations
Takes stains and finishes well. Staining can help even out the olive/tan color variations. Penetrating oils and polyurethane are recommended for durability. Caution needed with water-based finishes due to tannin bleed.
Identification Confidence
High; the end-grain pore structure visible in the cross-section, the 'RO' (likely Red/Rough Oak) marking, the olive-brown hue, and the characteristic checking/cracking pattern are all hallmark traits of Quercus alba.
