Alternate Names: KT1-4, KT#1-4
A coarse-grained, fast casting Ball Clay used in all types of casting applications, but primarily used in artware. It is a blend containing mostly SGP#1 and some OM#4. It is blended to specification (thus the blend is adjusted as the constituents vary to maintain physical properties). KT1-4 is slightly less plastic than CDI blend, but more plastic and thus less sensitive to deflocculants than SGP.

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.
