But first it is always good to do a small scale test when trying out casting processes. This is my test, a small clay sculpt. The shim line, where the cast will split apart, is simple and flat.With such a small sculpture, casting it is very simple. You start by making a batch of plaster, while it is still runny you can flick, drizzle, or brush on the plaster. This will capture the details. As it hardens and begins to get the consistency of mashed potatoes, begin to build up the cast until it is about two inches thick. Be sure to level off the plaster on the shim metal so it is easier to line them up in the coming steps.
