The decoration is made using a process called mishima. After each bowl has been completely formed and is hard leatherhard, I use a very thin needle point tool to scratch my desired design into the surface. Once I have drawn the whole design, I load up a brush with black underglaze and paint over the design I have scratched. After the underglaze dries, I use a damp sponge to wipe excess off the surface. This leaves underglaze laid only into the design I initially scratched. The bowl is finished with a simple clear glaze.
