This elegant Kiyomizu-yaki porcelain yuzamashi (湯冷まし - water cooler) is made in a hyōtan gourd shape and is hand-decorated with the auspicious shippo (七宝) crest using the icchin (イッチン) technique. Icchin involves loading slip (liquid clay) into a piping bag, and trailing it onto the pot to create designs with dimension. On this piece, each shippo-mon is further accented by alternating dots of silver and gold at their centre. Yuzamashi are used to cool down boiling water to a temperature more suitable for brewing green tea. When poured into a yuzamashi, boiling water cools to roughly 90°C, which then will cool to roughly 80°C when poured into a cold teapot.
