White Oak
Quercus alba • Hardwood
Grain Pattern
Quarter-sawn and rift-sawn grain visible; notable for long, prominent medullary rays (flakes) and straight, coarse-textured grain. The end grain shows large, distinctive tyloses in the pores.
Color Description
Heartwood is a light to medium brown, commonly with an olive cast. Sapwood is light brown to whitish and not always sharply demarcated. Tends to darken and become more golden-brown with age and exposure to UV.
Hardness Rating
1,360 lbf (Hard)
Durability Rating
Very Durable; known for its high resistance to rot and decay due to tyloses that block the passage of moisture. Excellent insect resistance.
Common Uses
Cabinetry, furniture, interior trim, flooring, boatbuilding, barrels (cooperage), and tool handles.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$6.00 - $12.00 per board foot depending on the width and the prominence of the quarter-sawn ray flecking.
Wood Age Estimate
The sample appears to be from a mature timber, likely 40-60 years old based on the density of growth rings and the depth of the oxidation patina on the surface.
Sustainability Status
Least Concern (IUCN); widely available and not listed in CITES appendices. Frequently available with FSC certification.
Workability
Produces good results with hand and machine tools. It has moderately high shrinkage and can be prone to movement if not dried properly. Reacts with iron (turning blue/black) when wet due to high tannin content.
Notable Features
Features a distinct, spicy odor when being worked. High tannin content makes it suitable for fuming with ammonia to darken the color. The presence of tyloses makes it waterproof and ideal for wine and whiskey barrels.
Finish Recommendations
Stains and finishes well. Polyurethane or lacquer are excellent for durability. Oil finishes (like Tung or Linseed) beautifully highlight the medullary rays. Avoid water-based finishes without a sealer to prevent tannin pull.
Identification Confidence
High; the distinctive long medullary rays on the face and the cell structure visible on the end grain are classic indicators of Quercus alba.
