Report Pugmill Newby question in Studio Operations and Making Work Posted Sunday at 08:31 AM As others have said, needs to be full in order to get anything out the other end. I think we found we needed 3 buckets worth of mixed dry and sloppy clay to get it to work. We never had enough to process, and by the next time we wanted to use it we had to take to apart to get out the dried (set like greenware) clay out. No matter how many wet sponges we stuffed in it was always solid by next time we needed to use it. Haven't used ours for about 5 years.
