Description
A large oak, Quercus alba, native to eastern North America. White oak has a light brown, coarse-grain wood that is strong. The high quality wood is used for lumber, millwork, and flooring.
Synonyms and Related Terms
Quercus alba; chêne blanc (Fr.); carvalho branco americano (Port.); stave oak; roble; roblecito; mamecillo; encino; cucharillo
Other Properties
Medium tree growing to 30 m with spreading, oval crown Bark=light brown with blocky patches or scales Leaves=oblong (10-16 cm) with 7 to 10 rounded lobes. Fruit=long, oval acorn with warty cap, maturation takes one year
Paper fiber type: hardwood, ring porous. Using transmitted light microscopy, pulp is identified by two sizes of vessels with profuse pitting. The smaller late wood vessels of white oak will stain similarly to the early wood vessels, which can help distinguish pulp from Red oak. Vasocentric trachieds are worm-like and heavily pitted. Perforations are simple. Tyloses may be present. Appearance with Graff "C" stain: dark blue, but varies with bleaching. Average dimensions of fibers: length 1.47, 14-22μm wide. Common pulping method: kraft.
