When the figure is not level people cannot know what is meant by width, depth, or height without being told (or without labels), although length is generally still assumed to mean the direction in which the figure is longest..
Crude coal tar is a raw material which is further distilled to produce various carbon products, refined tars and oils used as essential components in the production of aluminum, rubber, concrete, plasticizers, coatings and specialty chemicals.oke is uses as a fuel and as a reducing agent in smelting iron ore in a blast furnace to manufacture steel and in foundry operations. Crude coal tar consists of a mixture of naturally occurring compounds containing hydrogen and carbon that are common to all organic fuels including coal, petroleum and wood.
The coal tars used are products of the destructive distillation of chosen grades of coal having low ash and good coking quality which produces a selective low carbon tar.Coal tar is the primary condensation product resulting from the carbonization of coal for making coke or gas; the tar is produced as a by-product.one Star coal tar coatings are products of carefully chosen coal tars having low carbon values, carefully blended with mineral fillers, carbon plasticizers and selected grades of heavy oils and solvents distilled from coal tar.
