This is a flat tea bowl commemorating the memorial tea ceremony for the 11th generation Soryu Koishi of the Matsuo school of tea ceremony. It appears to be unused. The item is in very beautiful condition. The white-based glaze has beautiful crackle patterns, and the inside of the bowl reveals the earthy tones of the clay in a calming color. The exterior is decorated with iron-painted brushwork patterns, exuding a simple yet powerful presence. There is a maker's mark on the side of the foot, suggesting the maker's reliable skill and history. The Matsuo school is known for valuing formality and elegance. This piece was made to commemorate the 11th generation Soryu Koishi and was produced as a commemorative item for a tea ceremony, making it a highly limited edition. It can be used for both usucha (thin tea) and koicha (thick tea) in the tea ceremony, and it also shines as a decorative tea bowl. We hope you will enjoy it for a long time, along with its background and story. Please check the photos for details. Photos (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
