At one time the slip (liquid clay) which was now free of grit and impurities was converted back into useful clay for pottery manufacture by evaporating off the water.

Burgess and Leigh installed the latest equipment in their modern factory and William Boulton engineers produced a filter press, of the type shown below. This press quickly removed the water from the slip.
