White Oak
Quercus alba • Hardwood
Grain Pattern
Straight, coarse grain with a medium to large pore structure. Visible cathedral pattern is beginning to emerge on the flat-sawn face, with small knots and characteristic medullary rays visible as fine lines/flecking on the radial surfaces.
Color Description
Light to medium brown with an olive cast. Sapwood is slightly lighter than the beige to brownish heartwood. It has a low to medium luster and typically darkens slightly with age, developing a warmer amber patina upon light exposure.
Hardness Rating
1,360 lbf (Hard)
Durability Rating
Very Durable. High tannin content provides excellent resistance to rot and decay. Frequently used for outdoor applications and boat building because of its tyloses-clogged pores which make it water-resistant.
Common Uses
Furniture, flooring, cabinetry, boat building, barrel making (tight cooperage), trim, and interior millwork.
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
Modern lumber, likely kiln-dried and processed within the last 1-5 years based on the crispness of the machine cuts and lack of significant oxidation or surface wear.
Sustainability Status
Sustainable; not listed on CITES Appendices or the IUCN Red List of Threatened Species. Widely available through FSC-certified sources.
Workability
Produces good results with hand and machine tools. It has a moderately high shrinkage rate, making dimensional stability a concern. It reacts with iron (turning blue/black) when wet due to high tannin content. Glues, stains, and finishes well.
Notable Features
Distinctive 'oaky' scent when being worked. Contains high levels of tannins which can cause corrosion in ferrous fasteners. Ring-porous structure is visible in the end grain.
Finish Recommendations
Polyurethane or oil-based finishes work best to bring out the depth of the grain. If staining, a wood conditioner is recommended, though it takes stains very evenly. Reactive 'fumed' finishes (using ammonia) can be used to create traditional dark Mission-style colors.
Identification Confidence
High. The color, visible open pore structure, characteristic 'cathedral' grain, and presence of medullary ray flecking are classic indicators of North American White Oak.
