It has low specific gravity, high nitrogen content and very lower sulfur content. It is non-carcinogenic and safe to handle in its natural state.
Development and production of this unique material began in 1885 when Samuel H. Gilson characterized the ore and named it Gilsonite.

In 1888, Gilson and a partner formed the Gilsonite Manufacturing Company, American Gilsonite first commercial ancestor. Gilsonite-brand uintaite's earliest applications included paints for buggies and emulsions for beer-vat lining. The name "Gilsonite" has been registered as a federal trademark since 1921 and is American Gilsonite Company's exclusive property.
