“Converting” a model to pressed clay terracotta

Started on the positive mold of my beaver sculpture by bringing the negative mold up from the basement and applying the release agent to it, after I have dinner I’ll be applying the rubber compound.

The mold in progress, and just after the 2nd application of rubber started to gel I poured the warm plaster in for the support shell. The heat from the setting plaster will help cure the rubber faster too. To-morrow I can take the negative mold apart and peel that rubber off the new and I’ll have a rubber positive with this plaster support inside it.

After filling the cavity with plaster for support

And here’s the rubber positive to use for making the plaster piece-mold to press terracotta in.
