Edgar Plastic Kaolin (EPK)

Material Overview

A secondary water washed kaolin mined in Florida. It is fairly plastic and very white firing compared with most other American kaolins. It has excellent casting properties. It is not plastic enough for throwing bodies, thus it should be augmented by a more plastic kaolin or by a plasticizer like bentonite or hectorite. EPK is considered by many to be the best North American kaolin for use in suspending glazes as it tends to produce a smooth thixotropic slurry.
Can be used as a release agent between glass and kiln shelving.
