CoroCoro - Guinomi -青備前

Toshiaki's "CoroCoro" Sake cup series. "CoroCoro" is a Japanese expression that describes something swaying back and forth. Just as the name suggests, this piece is designed to be placed on a table and sways gently when nudged (but don't worry, it's designed not to tip over). 

This piece is a rare type of Bizen ware called "Ao Bizen（青備前）" which has a slightly bluish-green tint. It is a highly valuable work of art as only a small percentage of pieces can achieve this color in a single kiln firing.
