White Oak
Quercus alba • Hardwood
Grain Pattern
Straight to slightly wavy grain with a coarse, uneven texture. The sample shows a flat-sawn cathedral pattern toward the top and includes a dark mineral streak and small knots.
Color Description
Heartwood is a light to medium brown, commonly with an olive cast. Sapwood is light off-white to light brown. Notable for dark grey/black mineral staining (reactive iron staining) and slow oxidation to a richer amber tone over time.
Hardness Rating
1,360 lbf (Hard)
Durability Rating
Very Durable; excellent resistance to rot and decay due to tyloses in the pores that make the wood nearly liquid-tight.
Common Uses
Furniture, flooring, cabinetry, boatbuilding, barrels (cooperage), trim, and heavy construction.
Geographic Origin
Eastern United States
Market Value & Sustainability
Estimated Market Value
$6.00 - $12.00 per board foot depending on width and grade (Character grade shown).
Wood Age Estimate
Recently milled from reclaimed or air-dried stock; the presence of fresh planed surfaces alongside deep oxidation/weathering on adjacent boards suggests the sample itself is likely 1-5 years post-milling, while the tree age was likely 80+ years.
Sustainability Status
Highly sustainable; widely available and not listed on CITES Appendices or the IUCN Red List of Threatened Species.
Workability
Easy to moderately easy to work with hand and machine tools. It has a high shrinkage rate, so dimensional stability can be an issue. Glues, stains, and finishes well.
Notable Features
Distinctive tannic scent when worked. High tannin content can cause dark staining when the wood comes into contact with iron and moisture.
Finish Recommendations
Polyurethane or oil-based finishes are recommended to enhance the grain. Penetrating oils (like Tung or Danish oil) work exceptionally well with its porous structure.
Identification Confidence
High; the combination of the specific ring-porous grain structure, the 'wheat' color with olive undertones, and the characteristic reaction-based mineral streaks are classic indicators of North American White Oak.
