A small amount to significant fractions of quartz are also found. If the chemical composition of pure kaolinite powder (39.5% alumina, 46.5% silica, 14% water) is compared to the composition of a typical kaolin or ball clay, the presence of silica is apparent. For example, a frequently used ball clay contains about 52% silica and only 32% alumina.
