This ceramic Mizusashi is an essential vessel for holding fresh cold water within the tea room (chashitsu). Used during Chanoyu (the Japanese tea ceremony), the Mizusashi is central to procedures like refilling the kama (kettle) or rinsing the chawan (tea bowl). This particular ewer features a striking, deep blue glaze offset by a dark, tactile kakegusuri (drip glaze) around the shoulder. Dated circa 1970, this piece offers functional utility and a vibrant aesthetic for any serious practitioner's collection of traditional Japanese tea supplies.
