Kaolin is a fine clay mineral cream to dark brown, colored by iron oxides/hydroxides (and/or rutile/anatase). Its major constituent is kaolinite (Al 2 O 3 ∙2SiO 2 ∙2H 2 O), a hydrous aluminum silicate with a single silica tetra hedral layer linked through oxygen atoms to a single alumina octa hedral layer.
