Notes

54S has a little more carbon that No. 5 (but is still low in carbon and other residue compared to most other ball clays). It is also a little more plastic. It is produced at their Hickory KY processing plant and is characteristic of the good plasticity and dry strength qualities historically associated with original grades of clay produced for years from this region.

Typecodes	Ball Clay Ball clays are abundant and very plastic and are used in all types of plastic forming bodies. They are not as white-burning or refractory as kaolins but lower in iron and fluxes than bentonites.
