I've been rather busy these last few weeks with my first projects for my ceramics class. I chose to make cups and saucers because of a long family history of collecting these items, so it's time to put my own spin on them. Below are some images of what I've been working on. I currently have a few of these pieces in the kiln and will soon be glazing and finishing the rest of them. I will post some images once they are finished.
Here is the model for one of the saucers surrounded by cottle boards ready to be cast in plaster. The model was formed by creating a wooden template for the top and bottom of the saucer. Then a spacer was used to create the depth needed and the void was filled with clay and molded into the correct shape. Once the plaster was poured, the model was removed, leaving a void that can now be filled with casting slip, forming a saucer.
Here you can see the finished model. The "saucer" part is the oval sculpture with a niche carved out to take the "cup" which is now a sold form, but will be a hollow cup once the mold has been cast with slip. The next step is to create a two part mold for each piece. A two part mold is required in this case (as opposed to the "drop out" one part molds shown above) because of the curved under cuts on these forms. The mold is made by filling in half of the mold cavity with clay then filling the top with plaster. The cottle boards are then taken off, the clay is remove, the mold is flipped over and the second half of the mold is cast in plaster, remembering to leave a hole to pour slip into ;)
