SLIP-CAST PROCESS

 

The process of making slip-cast porcelain editions include multiple time- and labor consuming steps. It starts with creation of an original sculptural or functional object which becomes a Model, or Prototype. I usually create a model/prototype in clay, plasticine (oil based clay) or epoxy clay. Some functional objects that have to be perfectly round are turned on the lathe. After the model is finished, I make a waste mold to create a plaster variation of a model. This plaster version is then sanded and polished to perfection in order for each porcelain cast to come out of the mold perfectly smooth. 

The next step would be creating a plaster Slip-Cast Mold from the plaster model.This plaster mold can be as simple as one piece or as complicated as 30 pieces. Plus, some complex objects require a few molds to produce one piece each that then are assembled together after casting. 

When the plaster mold is done, the next step is pouring liquid porcelain which is called Slip into the mold. This way I create perfect porcelain replicas of the original model.

When the porcelain casts are dry, they are cleaned from seams, sponged, dried and fired in a ceramic kiln several times each. After each firing, necessary decorations are applied, like glazing, underglaze and overglaze painting and gold luster applications. It may take up to five firings to complete a piece. Firing temperatures fluctuate from 1252 F to 2280 F (668 C to 1236 C).

Since each piece is hand-cast and hand-painted, it is unique and might slightly differ from other pieces.
