bitumen is a general term for a group of combinatory material from heavy hydrocarbons which are flammable and are solved in aromatic and aliphatic solvent. Gilsonite is a natural hydrocarbon which is a brittle and shiny material and highly brittle in case of high purity.

Gilsonite production in 2012 is valued at approximately $89 million, at an average price of about $1085 per short-ton (as reported by the U.S. Office of Natural Resources Revenue).

Gilsonite is easily combustible and emits toxic fumes when it burns (NOAA, 2017). Asphalt fumes and vapors from paving and roofing are associated with eye, nasal and throat irritation. Occupational exposures can also cause nausea, skin irritation, stomach pain, headaches and fatigue.

Gilsonite is used in the manufacture of wire insulation, paints, and varnishes, construction materials, asphalt, printing ink, oil well drilling, drilling Fluid and in foundry casting.
