Gilsonite Physical Specifications

Gilsonite mineral is exploited from the nature in different ways. In most cases Gilsonite or any other type of natural bitumen, is a solid substance. However, depending on the area of availability, the softening point can change. For example Iran Gilsonite has softening point of mostly 160-220 degrees Celsius, while Trinidad natural bitumen has a softening point below 100 degrees Celsius, making it called “Trinidad Lake Asphalt”, since the material is soft and almost liquid under temperature of the sun.
