Plasters are synonymous with clay processing, both for their water absorption and self-cleaning properties. Most tooling for clay products is based on the premise that the ability of plasters to absorb water depends on the porosity of the plaster being used, coupled with the point of saturation where the plaster will no longer absorb efficiently. Plasters and cementious material hybrids have been formulated for greater compressive strength and resistance to abrasive wear than the traditional plasters, but they often lack porosity.
Though not limited to cementious plaster hybrids, air release die and mold fabrication processes have been developed to open ...
