Description
Any of several Oak trees, such as Quercus rubra, Quercus borealis, or Quercus falcata, native to eastern North America. Red oak trees have a hard, coarse-grain wood that is widely used commercially for flooring, furniture, cabinets, paneling, and millwork.
Synonyms and Related Terms
northern red oak (Quercus rubra, Quercus borealis); southern red oak (Quercus falcata); willow oak (Quercus phellos); scarlet oak (Quercus coccinea); pink oak; chêne pourpre (Fr.); carvalho vermelho (Port.); quercia rossa (It.)
Physical and Chemical Properties
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 red oak will stain darker than the earlywood vessels, which can help distinguish pulp from White oak. Vasocentric trachieds are worm-like and heavily pitted. Perforations are simple. Tyloses are not present. Appearance with Graff "C" stain: dark blue, but varies with bleaching. Average dimensions of fibers: length 1.47mm, 14-22μm wide. Common pulping method: kraft.
