The kuppi series is produced using a technique called "inkante". For "potion" and "sasa", we dug up the stamps that have been sleeping in Arita's Taseigama kiln for a long time, changed the composition, stamping method, paint and texture, and re-edited them to create a modern design. A seal maker hand-carves the completed pattern design into a stamp, and a craftsman at the pottery hand-presses each stamp with rust glaze. Hand-drawn pattern design, hand-carved, hand-pressed stamps and three-step handwork create "variability". The new patterns "tile", "nord", and "pam" have been drawn to make use of the "variation" created by the three stages of handwork. hibi considers "good" the "variation" caused by nature and people, the characteristics of pottery and handiwork. The general image of Arita porcelain is that it is pure white and smooth and dyed, but the kuppi series explores other possibilities and uses the ancient technique of stamping, instead of pure white. I aimed for something new and nostalgic, a semi-matte rather than beige and smooth. As a result, wares with the strength and lightness of porcelain, as well as expressive expressions like pottery, were born.
