To make this style I made a simple upright bowl. I then cut out a section, textured it and re-added it to the bowl. I altered the rim and pressed it in. I think next time I will make a more obvious shape for the cut out similar to the cups I made last weekend which I will post as well. This bowl was made with Coleman Porcelain, Cone 10.
I then took some Plainsman H440 and threw a similar bowl. I made small balls of the Coleman Porcelain and attached them in a regular pattern.
I then pressed into those balls of clay with the end of a wood skewer and here are the results - a quilted look with contrasting clays.
