The shaw process and the unicast process.
Not only does ceramic mold making enable you to repeat a form over and over again it also makes individual forms lose their preciousness which frees you up to experiment more.
It is important to optimize the slurry composition in order to obtain high green density low green shrinkage and sufficient green strength to produce defect free demolding.
Ceramic mold making opens up endless potential for creative expression.
