What is Gilsonite?
Gilsoniteis a natural, resinous hydrocarbon. This natural asphalt is similar to hard petroleum asphalt and is often called a naturalasphalt,asphaltite, uintaite, or asphaltum. Gilsonite is soluble in aromatic and aliphatic solvents, as well as petroleum asphalt. Due toits unique compatibility, Gilsonite is frequently used to harden softer petroleum products. Gilsonite in mass is a shiny, black substancesimilar in appearance to the mineral obsidian. It is brittle and can be easily crushed into a dark brown powder.
Gilsonite 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. Theveins arenearly parallel to each other and are oriented in a northwest to southeast direction. They extend many miles in length and as deepas1500 feet. The vein will show up on the surface as a thin outcropping and gradually widen as it goes deeper. Due to the narrowmining face,Gilsonite is mined today, much like it was 50 or 100 yearsago. The primary difference is that modern miners use pneumatic chipping hammer sand mechanical hoists.

Gilsonite History & General Information
The mineral now know as Gilsonite was discovered in the early 1860's, butit was notuntil the mid-1880's that Samuel H. Gilson began to promote it as awaterproof coating for wooden pilings, as an insulation for wire cable,and as a unique varnish. Gilson's promotion of the ore wasso successfulthat, in 1888, he and a partner formed the first company to mine andmarket Gilsonite on a commercial scale.
Originally,Gilsonite wassold as "Selects" and "Fines"; the low softening pointore withconchoidal fracture was known as "Selects". The higher softening pointore with a pencillated structure was known as "Fines".Selects commandeda higher price than Fines because of its better purity, good solubility,and usefulness in the paint, stain, and varnish industries.
Timeand technology have changed this classification system. Processing ofGilsonite now removes most of the inert contaminants and newer, morepowerful, solvents make the higher softening point grades moreinteresting to the user. Today, Gilsoniteis graded by softening point(a rough measure of solubility) and particle size. All grades carry adegree of quality far superior tothose first small amounts of crudeGilsonite marketed in the 1880's.

ATDM history

From our plants we provide customers with a dependable supply ofmade-to-spec products in a variety of packaging options, including ourrefined blown bitumen also mixed Gilsonite with bitumen 60/70 andobtained through a proprietary solvent extraction process. Our productsare carefully screened for mesh, dried to controlled moisturespecifications from around 1.5%, classified by particle size, held inlarge concrete silos until ready for final packaging, and stored in acovered warehouse prior to shipment. Our labs conduct extensive qualitycontrols throughout the production process and every order is shippedwith an individual certificate of analysis that guarantees itsadherence to specifications.

Avizheh Technology Development of Middle East  (ATDM) isheadquartered in Tehran. Mining and processing are located inKermanshah. At Kermanshah ATDM operates a network of undergrounduintaite mines, a blown bitumen  refining plant, and a powdering plantwith multiple capabilities. Our plants have advanced materials handlingand packing facilities, storage silos and bins for 8,000 tons ofproduct and a covered warehouse with multiple loading docks. ATDMquality control labs conduct extensive product testing on every orderwe ship. ATDM currently has about 50 full-time employees, most of themworking at the Kermanshah Mine Site, and a worldwide agent anddistributor network.

ATDM has a long history of supplying its Gilsonite-brand nameproducts for the world market. The material now called Gilsonite ornatural bitumen, mineral bitumen, mineral tar, mineral pitch,bituminous, natural asphalt was discovered in the Kermanshah since2001. Modern geologists believe that the origin of Gilsonite is linkedto the rich oil shale of the Green River Formation that underlies muchof the basin. Deep vertical fissures in the earth's surface were oncefilled with a heavy, viscous hydrocarbon that lost its volatileconstituents and solidified millions of years ago.

Gilsonite is a glossy, black, solid hydrocarbon resin similar inappearance to coal or hard asphalt. It is brittle and lightweight andcan be easily crushed into powder. Its unique chemical propertiesidentify it as belonging to its own sub-group of the ATDM Gilsonitefamily. Gilsonite occurs naturally in a very pure state, and softens ina range of temperatures according to grade, from 302 to 464 degreesFahrenheit (150-240 degrees Celsius). It has low specific gravity, highnitrogen content and very lower sulfur content. It is non-carcinogenicand safe to handle in its natural state.

Development and production of this unique material began in 1885when Samuel H. Gilson characterized the ore and named it Gilsonite. In1888, Gilson and a partner formed the Gilsonite Manufacturing Company,American Gilsonite first commercial ancestor. Gilsonite-branduintaite's earliest applications included paints for buggies andemulsions for beer-vat lining. The name "Gilsonite" has been registeredas a federal trademark since 1921 and is American Gilsonite Company'sexclusive property.
