Slipcasting Ceramics Guaranteed results every time!

Demonstrating how I slipcast ceramic porcelain objects. I am making a replica of a shell using a 4 part plaster mold. I go through the entire process beginning to end.

I think of it as a niche of ceramics. Many artists, and in industry where it’s typically used, slipcast to easily replicate forms. Once the mold is made it’s easy to slipcast many pieces. Therefore most artists spend most of their creative energy on decorating the piece with various finishes. With few exceptions, slipcast work can be finished with the same processes as normal cream or throwing clays. Something I really like about slipcasting is it’s ability to make hollow forms. Think about that, most processes that use molds by default create solid forms. Concrete poured in a form comes out solid. Pour plaster into a mold, it comes out solid. A hollow form is hard to make in a mold. Slipcasting’s unique ability to make a hollow form is the foundation of many of my processes. Some specifics on the slipcasting process. After the liquified clay has been poured in the mold, water is absorbed by the plaster via capillary action. A residual skin is built up on the surface of the plaster inside the mold. capillary action of water absorbed into plaster mold Capillary action of water absorbed into plaster mold The longer the slip is left in the plaster mold, the thicker the skin becomes. You can think that the liquified clay is basically a liquid center with the clay skin as the shell, much like the liquid centers in a box of chocolates. After the slip has remained in the plaster mold long enough to develop a sufficiently thick shell (typically 20-60 minutes but can be longer), the liquid center slip is drained from the mold. The remaining shell can then be removed from the plaster mold. Slipcast ware tends to be fragile until it gets to the fairly dry leather hard stage. Once there a person can start applying finishes the same as other clays.
