Sone Clay and Glass Industry
994 Words | 2 PagesThe U.S. Bureau of Mines categorizes clay into six groups: ball clay; bentonite; common clay and shale; fire clay; fuller's earth; and kaolin. Ball clay is a plastic, white-firing clay that has a high degree of strength as well as plasticity. Principal ball clay markets in 1992 were pottery, floor and wall tile, and sanitary ware. Bentonite is a clay composed mainly of smectite minerals. The three major uses of bentonite in 1992 were drilling mud, foundry sand, and iron ore pelletizing. Common clay and shale contain mixtures of differing proportions of clay, including illite, chlorite, kaolinite, and montmorillonite, plus other nonclay materials. The largest user of these clays is the structural clay products industry, which manufactures brick, drain tile, sewer pipe, conduit tile, glazed tile, and terra cotta. Fire clays can withstand very high temperatures and consist mainly of kaolinite. These clays are used in commercial refractory products such as firebrick and block. Fuller's earth, either the attapulgitetype or montmorillonite-type, is used in pet waste absorbents, oil and grease absorbents, and pesticide carriers.
