I occationally cast a few small bits and pieces for my own use. So far, I've only done this using simple one-piece molds. Now, I need to cast a few parts that will require two-piece molds. My second attempt was successful, and the part actually looked great, no pinholes or anything. The problem, however, was the clay. This stuff was a real pain to remove. All the "how-to" videos I've seen, it just peels right away, slick as a whistle. Not so with me, it gets stuck in all the nooks and crannies....my first attempt at this mold I just threw away because I couldn't get all the clay out. Second go-round wasn't much better (see picture), but I finally got it so I could work with it after picking with toothpicks and knives and stuff all morning.
Am I doing this right? Am I using the right type of clay? Would putting it in the freezer for awhile help? This can't be normal....or can it?
Thanks, guys!!
