Natural Gilsonite is non-hazardous and is not toxic
Gilsonite (Asphaltum) -200 Mesh
Gilsonite, also known as asphaltum, is a naturally occurring solid hydrocarbon with a relatively high melting temperature.
Gilsonite is used in some report compositions because it generates smoke that obscures the already-weak light output of a chlorate/antimony report. It can also be used for black smoke and fireball effects.
