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.Physical Properties =================== Water of Plasticity: 33.0% % Dry Shrinkage: 6.8 Dry M.O.R., psi: 576 Dry M.O.R., psi*: 415 Soluble salts, ppm: 229 (Med) pH: 5.8 C.E.C., meq/100g: 10.5 P.C.E.: 30 Particle Size, Microns (% finer than): 100 mesh: 0.03 200 mesh: 0.22 325 mesh: 0.57 Fired Shrinkage (%): Cone 02: 4.3 Cone 3: 5.5 Cone 8: 7.2 Cone 11: 8.6 Total Shrinkage (%): Cone 02: 10.7 Cone 3: 12.6 Cone 8: 14.1 Cone 11: 15.8 Absorption (%): Cone 02: 13.1 Cone 3: 9.9 Cone 8: 4.3 Cone 11: 0.0 Color: Cone 02: white Cone 3: cream Cone 8: cr-grey Cone 11: grey -- -- -------------- *Extruded, 50% ball clay, 50% flint +Low-trace to 150, Med-150-400, High-450+

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. |
