The openwork technique, where motifs are carved out of the porcelain surface with a sharp knife, is not really suited to the character of porcelain clay. The technique has been used in Mikawachi, however, since the Edo period. Using this technique, the Gyokusen kiln produces traditional forms such as multi-level towers and decorative censers. They also create work made to order, and daily utensils such as incense burners and chopstick rests.
