When it comes to Gilsonite Powder, it is categorized on the basis of Ash Contents and the Mesh Size. Gilsonite was formed by a unique geologic event millions of years ago that caused a proto-petroleum

deposit forming at that time to fill large surface cracks, later solidifying into the pure resinous rock mined

today. Gilsonite is hand-mined in underground shafts using pneumatic jack hammers.

The Mesh Size needs to be informed to the supplier when placing the order which can be 30, 40, 100, 200,

etc.

It is shipped in the following packing:

1. Palletized 25 Kg Bags

2. Jumbo Bags of 1 MT or 1.25 MT

3. 25 Kg Bags placed inside Jumbo Bags.
