About 2 weeks ago I came up with an idea for an Alien and a Skeleton doll. At that time I started to sculpt the original pieces out of clay and then made master plaster molds of them. Now that the molds are dry I am able to cast them in slip (liquid clay), make a few changes, refine them and production molds can be made from those pieces. I'll make many so that I can pour lots of pieces without having to wait for the molds to dry before I can start casting again. After pouring the production molds, waiting for the clay to set up, removing the parts from the molds, seams and pouring spouts can be removed and a final smoothing and refining of the parts is done. I'll have to wait for those parts to dry and then the parts will be put in a kiln and fired. Only after all that can I start actually working on the doll body. Phew, Makes me tired just thinking about all the steps!
