Today I finished off making my tumbler slip cast mold. I started my filing down the two parts I had made last week. I keyed in 3 lock holes and the cleaned and soft soaped the top surface. Instead of drilling into the top section after casting as I had done with the previous mold, I built a clay cone on top.
I am very pleased with the accuracy of this mold. It has worked much better than the goblet mold as it was far less complicated to make. I have left the mold to dry for three days before I will try using it for slip casting.
