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.
