Jomon Spiral, by Ayumi Shigematsu, is one of the many stoneware pieces offered at Dai Ichi Arts, Ltd. in their exhibition, Future Forms: Avant-Garde Sculpture in Modern Japanese Ceramics. Ayumi is part of a vanguard generation of highly influential post-war female artists in Japan whose practices are inspired by concepts of female sexuality and representations of nature. With this piece the artist reflects on the hand-building clay production founded during the Jomon Era. Jomon, or cord-patterned pottery, is a method of hand-building clay used by women during this period before wheel-thrown pottery traditions were established in Japan.
