ABSTRACT:
A method of forming complex shapes from soft solvent-containing batches and maintaining the integrity of such formed bodies. The formed bodies are made self-supporting immediately after forming or soon thereafter by contacting the shaped body with a drying or hardening liquid in which the solvent is soluble. A method is also disclosed for simultaneously drying a formed body and creating or increasing the porosity of the body by adding solid particles which are soluble in the drying liquid.
