Watanabe Aiko calls wood-fired items with earthy texture Shigaraki, even though these are fired in Iga. Iga and Shigaraki are geographically very close and share similar characteristics.
This piece has a dragonfly eye on the bottom (round green glass drop formed from ash during firing). It has a slight wobble due to the glaze.
