Making a two part mold part 2
The next step is to build up and fill in with clay to the parting line all around the models. The clay should be filled in carefully and should go straigh out from the parting line not slant downward to the edge of the mold. Keep the edges of the mold clean by frequently running a butter knife or similar tool along the grooves to shape the clay into a right angle at the edge of the groove. In the photo to the left you can see this process from several angles.
