White
Oak Species Information
Top portion is finished with water-base urethane; bottom with
oil-modified polyurethane.
Appearance
Color: Heartwood is light brown; some boards may have a pinkish
tint or a slight grayish cast. Sapwood is white to cream.
Grain: Open, with longer rays than red oak. Occasional crotches,
swirls and burls. Plainsawn boards have a plumed or flared
grain appearance; riftsawn has a tighter grain pattern, low
figuring; quartersawn has a flake pattern, sometimes called
tiger rays or butterflies.
Variations within species and grades: Considerable variation
among boards in color and grain texture, but variations not
as pronounced as in red oak.
Properties
Hardness (Janka): 1360; 5% harder than Northern red oak.
Dimensional Stability: Average (change coefficient .00365; 1%
more stable than red oak).
Durability: More durable than red oak. Tannic acid in the wood
protects it from fungi and insects.
Workability
Sawing/Machining: Excellent machining qualities.
Sanding: Sands satisfactorily.
Nailing: Good resistance to splitting; excellent holding ability.
Finishing: Absorbs finishes more evenly than red oak. Does not
bleach well.
Comments: During the finishing process, tannins at the surface
can react with some liquids to turn the wood green or brown.
This effect tends to be more pronounced with products that
have a high water content, such as bleach and water-based
finishes.
