EPK is considered by many to be the best kaolin for use in suspending glazes as it tends to produce a smooth thixotropic slurry. 15-20% will normally make the glaze gel slightly, thus when a piece is immersed in the slurry and removed it drips very little and the wet glaze layer stays in place for the time it takes to dewater.
EPK is and very white firing compared with most other American kaolins. It has excellent casting properties. But it is not plastic enough for throwing bodies, it must be augmented by a plasticizer like bentonite. Or, if whiteness can be sacrificed, by a ball clay.
