Very excited about this yunomi! I threw it on the kickwheel and I always throw a bit thick which is just natural for me. In throwing and trimming it forces you think about how the inside of the vessel is formed and how it will affect the balance and the overall shape.
This leads to an insight which is best explained by the Tao Te Ching –
Use What Does Not Exist
Thirty spokes are united around the hub of a wheel, but the usefulness of the wheel depends on the space where nothing exists.
Clay is molded into a vessel, but the usefulness of the vessel depends on the space where nothing exists.
Doors and windows are cut out of the walls of a house, and the usefulness of the house depends on the space where nothing exists.
Therefore take advantage of what exists, and use what does not exist.
