Other 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.
