I just completed run #4. I couldn’t wait; I had to know if my theory about the clay and the moulds was correct. Today’s run was the first attempt for my main character. Aside from the clay used in the original sculpt; there is essentially no difference in the entire process of creating this puppet and yesterdays. The puppet foamed up without incident which seems to confirm my theory, that the issues that have been occurring have something to do with the clay leaching something into the plaster mould. If recent history holds true, the remaining puppet, which has already been baked once, should succeed the next time I run it. This whole episode has left me exhausted.
