The ceramic goat skull is made in a plaster mold that was taken from a real goat skull. Hence it is anatomically accurate but about 10% smaller than the original because the clay shrinks this much when it is fired.

In these images I have arranged all the pieces of the goat skull mold to try to demonstrate how they fit together… and a finished skull.

The loose pieces of plaster are held together with very strong rubber bands, and the internal cavity is filled with liquid clay. The dry plaster absorbs water out of the thin runny clay and this action leaves a layer of thick clay on the surface of the plaster. When the layer of clay is thick enough the remaining slip is poured out of the mold.

The plaster is then pulled away from the clay which is exactaly the same as the original form, except that it is hollow.
