I manage a small park district studio with 10 wheels and three instructors. We order pre-moistened clay from AMACO and have for many years. Over the last year or so AMACO has begun to make the pre-moistened clay very wet. It is unusable out of the box and has to be dried before using. They told me they have done this to satisfy school programs. Has anyone else noticed this change? Is it a problem? Is there an easy way to dry out a 25 pound block without having to monitor it and rewedge it?
