Wood Species - White Oak
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.
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.
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
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
