A bowl to form the coil dish - I collect Fat Daddio’s hemispherical bowls. They are great for forming bowls, dishes, or even curved pieces for pendants and earrings and they have a frosted surface that will not make shiny marks on oven bake clay. The bowl I used for this project is 4.5” in diameter but any bowl size can be used. The diameter of the bowl will change the depth of the dish. The important thing is that the bowl has a non shiny surface. You can use any bowl you wish for the form, but if it has a shiny surface, the clay coil dish will mimic that shiny surface when baked.
