Ceramic Processes

“To make my work, I begin with one of two processes. Either I cast a solid shape from plaster and carve it into the form I am after or I turn setting plaster on the wheel. This is called sledging. To do this I use a profile rib to form a round solid plaster model. Next I carve an intricate grid based pattern of intersecting geometric shapes into the surface. After the plaster “model” is complete, I create a 6 part complex plaster mold by hand. This is a slow careful process as any mistakes in the mold will be present in every piece produced. I carefully mix porcelain casting slip, then pour it into the mold. When the piece has reached the desired thickness, I pour out the remaining slip. Once the piece is dry I spray a colored slip on the surface. The colors that I use come from ceramic stains and are food safe and non toxic. The next step in the process is a bisque firing. Once the piece comes out of the kiln, I wet sand the entire surface to give it a smooth, satin matt feel using wet dry sand paper and diamond abrasives . Once the Piece is dry, I line the interior with a clear glaze, then fire the piece to cone 9.”
