The source objects for the guinomi were created as digital 3D forms before being rendered as physical objects using rapid prototyping technology. Casts taken from these generated objects were used to create the vessels using liquid porcelain, sometimes mixed with oxides, in a slip cast process. Exterior surfaces are often unglazed and always hand polished to give a smooth, undulating surface to fit comfortably into the hand. The interiors are glazed with clear, rare earth, or ice blue celadon glazes. The guinomi are complemented with sake flasks, tokkuri, created using the same materials and processes.
Here are some images of how the work looks in the exhibition:
