Know Your Wood: White Oak

White Oak
An example of the medullary rays of a quartersawn piece of White Oak, presented by The Wood Explorer.

Trade Name: White Oak.

Genus: Quercus alba

Janka Hardness (pounds-force): 1360

Description: Light to medium brown, sometimes sprinkled with pinkish hues. Red Oak is usually a darker red, but color is no way to differentiate the species. The primary difference is on the cellular level. White Oak is a superior exterior performer than Red Oak due to the tyloses providing a closed cellular structure, making it more rot- and water-resistant. White Oak was the preferred species for many of Gustav Stickley’s Arts and Crafts designs at the turn of the previous century.

Location: Typically, Eastern United States.

Common Aliases: Cucharillo, Encino, Mamecillo, Roble, Roble Colorado, Stave oak

Performance: White Oak is solid, durable, relatively easy to work, well pored, and coarsely grained. White Oak finishes very well. It is affordable, abundant, and can offer a wide array of appearances, depending on what the designer has in mind, and depending on the particular cut of the lumber. Insects such as ambrosia and Butrespid beetles will get right after this species, sadly.

General Washington would have been proud of Connecticut's efforts once his views of the Monarchy had galvanized. Check your state quarter sometime!

Common Uses: Staves, barrel making, boat building, outdoor furnishings, cabinetry, tables, chairs, craftsman designs, flooring, moldings, millwork, veneer, and a variety of other uses.
