These mugs are on a plaster table, just thrown on the wheel. I made the box cover from a large sheet of cardboard and painted wax emulsion on the inside. I drew a line on the plaster for its boundaries. When left overnight under the box the mugs dewater evenly, the plaster pulls water from the air in the box and directly from the thicker bases. In the morning they are stiff enough for handle attachment and to turn over on an arborite bat for a little more drying to ready them for trimming. An big advantage of this method is that I can throw ware minutes before closing time, come back in the morning, and they are ready. And they do not experience the unevenness in drying that normally happens when pieces are left to air dry (after throwing) until they are stiff enough to support a cloth and plastic to cover them.
Drying Ceramics Without Cracks
Anything ceramic ware can be dried if it is done slowly and evenly enough. To dry faster optimize the body recipe, ware cross section, drying process and develop a good test to rate drying performance.
