"Barite is a widely distributed mineral composed of barium sulphate - BaSO₄. Its most striking feature is its weight - its specific gravity of 4.5 being about twice that of salt and many other of the colorless, transparent and vitreous minerals of its general appearance. The Mineral is usually found in a state of considerable chemical purity. However, small amounts of strontium and calcium sulphates may isomorphously replace the barium salt. Crystals of barytes are orthorhombic; usually very perfectly developed and have a wide variety of forms. The simplest crystals are rhomb-shaped tables bounded by two faces of a basal pinacoid. The mineral has a very smooth and bright cleavage parallel to both sets of planes. The crystals may be transparent and colorless; or white and opaque; or yellow, brown, bluish or greenish in color. The mineral also occurs in a granular, earthy or stalactitic condition. Parite is of common occurrence in metalliferous veins, especially those containing ores of lead and silver"--Consumption, Production and Prices of Crude Barite, page 1.
