How to Make a Glazed Wall Plate
Decorate your walls with plates that shimmer with a crystalline ceramic glazing technique.
Materials and Tools:
pre-made plaster hump mold
kiln (electric or fuel)
1. Cut six pounds of clay with a cutting wire to make a 15-inch plate.
2. Wedge it for 15 seconds to soften the clay and make it pliable.
3. Wet the plaster mold with water using a sponge.
4. Throw the clay on the mold, wet the clay with water (spritzing with your fingers) and begin to cone the plate.
5. Apply pressure on the outside of the clay to cause it to go up (coning). This process makes the clay more consistent and helps the potter center the clay.
6. Form the foot by pressing into the clay in two places, creating an indentation. Squeeze the excess clay with your fingers and round off to form the foot. Spread the clay out to cover the plaster bat using the palm of the right hand and pushing down while simultaneously moving out.
7. Spread the clay out to cover the surface of the plaster a little at a time. Before you get to the desired size of the plate, leave enough clay to form the foot.
8. Once the foot is shaped, finish spreading the clay out to desired size and undercut the outer edge.
9. Remove the plaster from the wheel and allow it to dry for 24 hours.
10. Remove the plate from the plaster and place it right side up on the potter's wheel.
11. Slowly spin the wheel and center the pot by holding the foot. Trim the edge of the pot with a trimming tool.
12. Clean the edge of the pot with a damp sponge.
13. Allow the pot to dry for three days and then bisque fire to cone 04.
14. Glaze bisque the pot using the potter's wheel, brushes and glaze bottles. Note: Glaze the bottom of the piece first. Use this technique:
- Center the pot on the wheel and squeeze glaze out of the bottle while spreading it with a brush.
- Move gradually with both glaze bottle and brush until the surface is fully glazed.
15. High fire the wall plate to cone 11 in an oxidation atmosphere using a crystalline glaze firing profile. You can do this in an electric or fuel kiln.
