This shipment of light EPK (there are two versions, light and dark) is just barely plastic enough to make this cylinder with a slight belly. Notice the splits on the rim, these are indicative of the shortness (low plasticity). The cohesiveness of the material, as much as plasticity, gives it a toughness to survive the stresses of throwing (an unique aspect of EPK).
Testing a New Load of EP Kaolin
A kaolin that gels slurries (thus handy to suspend ceramic glazes). It is plastic and fires white enough that it is also valuable in porcelain bodies.
