Appalachian
White Oak
(Quercus alba)
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 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: 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 fungus 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.
