A Longquan celadon bucket-shaped water pot, mizusashi, Early Ming dynasty 明初 龍泉青釉桶式水指

Water pots (known as mizusashi in Japanese) in the form of a handled bucket are one of the most iconic utensils used in Japanese tea ceremonies. Vessels of such form were believed to be containers for fresh water to fill either the teabowl or the kettle, and were widely commissioned to tailor for the Japanese market.

水桶式水指，乃日本茶道具中一經典器型，用於盛裝清水以清洗茶盌或舀水入茶釜內。此形制借鑒自日本傳統木水桶，配龍泉青釉釉潤翠青，在茶儀式中與茶盌同為鑑賞之物，廣受日本市場青睞。
