Conventional sanitaryware production uses plaster molds, which operate on the principle of capillarity--the same system that allows plants to transport water from their roots to the highest leaf without the aid of any other mechanism. The plaster works like a sponge and "sucks" the water from the slip. Plaster molds operate at low pressure and are relatively inexpensive, but they do carry several drawbacks. Forming and reuse times are quite lengthy, and the molds typically have a l...
