High drying shrinkage of Plainsman A2 ball clay (DFAC disk)

Friday 21st October 2011

This DFAC test disk shows the incredible drying shrinkage that a insight-live.com/material/80">ball clay can have. Obviously if too much of this is employed in a body recipe one can expect it to put stress on the body during drying. Nevertheless, the dry strength of this material far exceeds that of a kaolin and when used judiciously it can really improve the working properties of a body giving the added benefit of extra dry strength.
