This shows the tail modelling completed over the aluminium tail patch. The tail can be lifted off the rest of the horse without disturbing the modelling.

This model can be thought of as the first positive. The plastilene is too soft to use the model to make plaster moulds. It is necessary to make a permanent model. The next step is then to make a negative of this model. I call the negative the intermediate mould. From this I can make the intermediate positive, or rubber permanent model. This permanent rubber model is used to make the plaster production mould (another negative) and out of that mould comes the final positive, the clay slip-cast horse.
