What is gilsonite

Gilsonite or Asphaltum is a natural asphalt resinous hydrocarbon found in western Iran on 1930. This natural asphaltite is a hard Hydrocarbon and is often called a natural asphalt, asphaltite, uintaite, or asphaltum. Gilsonite is soluble in aromatic and aliphatic solvents, as well as petroleum asphalt. Due to its unique compatibility, what is Gilsonite is frequent question for somebody who does not know about this unique material.It is used to harden softer petroleum products. 

Where is gilsonite?

Gilsonite in mass is a shiny, black substance similar in appearance to the mineral obsidian. It is brittle and can be easily crushed into a dark brown powder.It is found below the earth’s surface in vertical veins or seams that are generally between two and six feet in width, but can be as wide as 28 feet. The veins are nearly parallel to each other and are oriented in a northwest to southeast direction. They extend many miles in length and as deep as 1500 feet. The vein will show up on the surface as a thin outcropping and gradually widen as it goes deeper. Due to the narrow mining face, it is mined today, much like it was 50 or 100 years ago. The primary difference is that modern miners use pneumatic chipping hammers and mechanical hoists.

History of Gilsonite

The mineral now known as "Gilsonite" or Asphaltum was discovered in the early 1860’s, but it was not until the mid-1880’s that Samuel H. Gilson began to promote it as a waterproof coating for wooden pilings, as an insulation for wire cable, and as a unique varnish. Gilson’s promotion of the ore was so successful that, in 1888, he and a partner formed the first company to mine and market on a commercial scale. Originally,it was sold as “Selects” and “Fines”; the low softening point ore with conchoidal fracture was known as “Selects”. The higher softening point ore with a pencillated structure was known as “Fines”. Selects commanded a higher price than Fines because of its better purity, good solubility, and usefulness in the paint, stain, and varnish industries. Time and technology have changed this classification system. Processing now removes most of the inert contaminants and newer, more powerful, solvents make the higher softening point grades more interesting to the user. Today, it is graded by softening point (a rough measure of solubility) and particle size. All grades carry a degree of quality far superior to those first small amounts marketed in the 1880’s.

Gilsonite Compatibility

What is Gilsonite? It is compatible with Microcrystalline and Paraffin Waxes, Petroleum Resins and Oils, Rosins, Tall Oil Pitch, Vegetable Oils (Linseed, Soya, etc.), Petroleum Process Oils, and Petroleum Asphalts.

Compatibility with Commercial Resins

The following is a general guide to the compatibility of its resin in common film-forming and elastomeric systems. Because it is compatibility can be influenced by variations within a resin/elastomer class and by other components in a formulation, it is good practice to verify ( Gilsonite ) compatibility in the specific formula of interest.

Since Gilsonite is trademark name and using this name needed approval,many companies choose other name to call to Gilsonite.There is some benefit in this branding since Gilsonite is offering by everybody and price is recognized by end buyer but when suppliers pack the product under other name they can sell it in more value.This kind of branding mostly there is drilling mud.Famous brand  and trademark of GilsoniteConfri trolAsphasolOrganophilic ligniteGilsonitaAsphaltumSulphonated [...]
