Bitumen is also frequently called tar or pitchâthough, properly speaking, tar is a byproduct of the carbonization of coal and pitch is actually obtained from the distillation of coal tar. Bitumen is defined by the U.S. Geological Survey as an extra-heavy oil with an API gravity less than 10Â° and a viscosity greater than 10,000 centipoise.
Also known as asphalt or tar, bitumen was mixed with other materials throughout prehistory and throughout the world for use as a sealant, adhesive, building mortar, incense, and decorative application on pots, buildings, or human skin.he earliest reed boat discovered yet was coated with bitumen, at the site of H3 at As-Sabiyah, about 5000 BC.
