PCE - Pyrometric Cone Equivalent 24

A coarse-grained, siliceous, illitic Ball Clay known for its high strength and plasticity. Applications include artware and ceramic tile. The high free silica content means that bodies with a high percentage of this material could cause certain glazes to shiver.
