Ben used Solidworks to design these mugs that a normal Ball Jar lid could screw on two. We calculated the shrinkage precisely and the master molds were cnc milled from high density foam. With these molds he was able to cast multiple production molds. He cast and crafted these mugs so well that even the very first one was glazed worked.
Object lesson is an experiment in the design and production of ceramic objects from students of various disciplines. All the projects shown are cast in porcelain, molded from both hand carved and machined forms.
