Caption reads: Photograph 8
Filter presses in which water is forced out of the body which has just been ground and lawned. This body or "slip", as it is called in the liquid state, is about the consistency of cream until filtered, at which stage sufficient water has been removed to make the body stiff enough to model or form into shape.
