Many people think that cast sculptures acquire their detail strictly from the clay model, but what they don’t see is the secondary process that creates the accuracy of the finished work. The Technique for plaster moulding is simple. To get into the detailed inner layers, you have to use something with a soft tip like a small brush that can fit into crevices. Once you’ve made a first layer that covers every detail in wet plaster, then a palette or dabbing medium can be used to increase the layer mass and make the mould more durable. Moulding can take a bit of time, but it is a crucial step in the formation of fine precision artworks and sculptures.
