| Plaster is built up over the back just like it was on the front. Once it hardens, all the water-based clay is removed, and you have a sculpt completely surrounded by plaster. | Now the two halves of the mold are carefully pulled apart. The sculpt is removed, and the mold cleaned of all clay residue. If any clay is left, the casting will not set up properly. | |||||||
