A very fine grained, naturally occurring clay or claylike mineral possessing a high adsorptive capacity. Although the term is applied without any reference to any particular chemical or mineral composition, texture, or origin, fuller's earth usually consists of the clay minerals calcium montmorillonites and palygorskites (attapulgites). The terms palygorskite and attapulgite are synonymous, but the international nomenclature committee prefers the term palygorskite, which predates the term attapulgite. Fuller's earth has been in common use from medieval times, when such clays and earths were used for “fulling” or cleaning raw wool to remove greasy lanolin and dirt before the wool was spun, dyed, and woven. In addition to high water absorption capacity, fuller's earth has the capacity to refine and decolorize edible oils. The first commercial fuller's earth deposit in the United States, which is still mined today, was discovered in 1893 near Quincy, Florida. Fuller's earth is produced in Algeria, Argentina, Australia, England, Germany, Italy, Mexico, Morocco, Pakistan, Senegal, South Africa, Spain, and the United States. The estimated production is about 4,000,000 tons annually. See also: Montmorillonite
