How to Make a Coiled Ceramic Bottle
Materials and Tools:
low-fire white modeling clay
blue painter's tape
bucket of water
bottle with fine needle tip
1. Cut several slices of clay from the clay loaf with the clay cutting wire. Cut each slice into four rectangular pieces with a sharp knife.
2. Roll each rectangle of clay into a long, thin coil.
4. Build the bottle by stacking coils on top of the base.
5. Smooth the clay with your fingers. Shape the bottle with a wooden paddle.
6. Let the bottle dry to the leather-hard stage. Smooth the sides with clay tools and wet sponges.
8. Let the bottle dry completely. Re-carve the design and smooth the surface.
10. Using black glaze in a squeeze bottle with a fine needle tip, apply the glaze to the incised pattern. Remove excess glaze with a wet sponge.
11. Glaze-fire the bottle in the kiln.
12. To prepare the bottle for the background glaze, mask off the block designs with blue painter's tape cut precisely with a craft knife. The tape must cover the area inside the carved lines of the blocks.
13. Apply the brown background glaze to the ceramic bottle with a paintbrush. Paint over the masking tape.
14. Remove the masking tape.
15. Apply three coats of colorful glazes to the block pattern with an artist's brush.
