White Oak
Quercus alba • Hardwood
Grain Pattern
Straight-grained with a medium to coarse texture; visible large pores characteristic of a ring-porous species. Shows slight cathedral figure and subtle ray flecks common in flat-sawn cuts.
Color Description
Heartwood is a light to medium brown with olive/tan undertones. Sapwood is light cream. The sample shows a weathered gray patina and dark tannic staining (mineral streaks) from moisture exposure/iron reaction.
Hardness Rating
1,360 lbf (Hard)
Durability Rating
Very Durable; heartwood is highly resistant to decay and rot due to tyloses in heartwood pores that prevent water absorption.
Common Uses
Furniture, flooring, cabinetry, boatbuilding, barrel making (cooperage), and exterior millwork.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$6.00 – $9.00 per board foot
Wood Age Estimate
The sample appears to be reclaimed or secondary-use wood, likely 30-60 years old based on the oxidation, deep vertical checking, and grey weathering on the surface.
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
Produces good results with hand and machine tools. Has high shrinkage, so seasoning is critical. Reacts with iron (turning blue/black) when wet due to high tannin content.
Notable Features
Distinctive tannic scent when cut; contains tyloses which make the wood waterproof; high tannin content can cause allergic skin reactions in some people.
Finish Recommendations
Oil-based stains, polyurethane, or oil-and-wax finishes. If used outdoors, a UV-inhibiting sealer is required to prevent further graying.
Identification Confidence
High; the open-grain structure, tan-to-olive color cast, and specific dark mineral stains are classic indicators of Quercus species, specifically the white oak group.
