6.8.26 - we have a limited amount of EPK remaining.  For sale to existing customers only, limit 1 bag per person or 3 bags per university/arts center 

10.27.23 - Please note: we had heard reports of recent loads of EPK showing black specks in the firing. We tested the batch we received last month and found no black specks or any other contaminants.

E.P.K. stands for Edgar Plastic Kaolin, and is a kaolin mined in Edgar, Florida. This material fires white and is loved for its stickiness when wet and thixotropic properties. 15-20% will make a glaze slurry gel and allow bisque ware to be dipped in the glaze. While this material is good for casting, it does not have enough plasticity to be good for throwing clay bodies on its own. In that case, more plastic kaolins or a plasticizer can be added to the body.
