fuller's earth, mineral substance characterized by the property of absorbing basic colors and removing them from oils. It is composed mainly of alumina, silica, iron oxides, lime, magnesia, and water, in extremely variable proportions, and is generally classified as a sedimentary clayclay,
common name for a number of fine-grained, earthy materials that become plastic when wet. Chemically, clays are hydrous aluminum silicates, ordinarily containing impurities, e.g., potassium, sodium, calcium, magnesium, or iron, in small amounts.

It was originally used in the fulling of wool to remove oil and grease but is now used chiefly in bleaching and clarifying petroleum and secondarily in refining edible oils. Fuller's earth is mined in many parts of the United States, Georgia and Florida being the leading producers, and in England near Reigate, Nutfield, and Bath. Before it can be used, it has to be crushed and dried.fuller's earth[¦fu̇l·ərz ¦ərth] (geology) A natural, fine-grained earthy material, such as a clay, with high adsorptive power; consists principally of hydrated aluminum silicates; used as an adsorbent in refining and decolorizing oils, as a catalyst, and as a bleaching agent. fuller’s earthA naturally occurring earthy substance, somewhat similar to potter’s clay but lacking its plasticity; used as a poultice to remove stains from stonework on a building.fuller's earth
fuller's earth [ful´erz erth] an impure aluminum silicate that has decolorizing and purifying properties. It is an absorbent used in the management of paraquat poisoning; the mode of action is by tightly binding paraquat to the clay in the formulation, which takes place in the gastrointestinal tract and facilitates elimination in the feces.ful·ler's earth1. an amorphous variety of kaolin of varying composition, containing an aluminum magnesium silicate. The name is derived from an ancient process of cleansing or "fulling" wool to remove the oil and dirt particles with a water slurry of earth or clay. 2. a refined clay sometimes used as a dusting powder or applied moistened with water as a form of poultice. Currently refers to any clay that can be used for the purpose of decolorizing in oil refining. Used as decolorizer for oils and other liquids, filtering medium, filler for rubber, and in agricultural formulations.
