"■ Title Master Lee Eun-koo (李殷九) – Sgraffito White Porcelain Water Jar (Mizusashi) with Peony Motif – Korean Studio Ceramic – Tea Ceremony Utensil – Late Showa to Heisei Period (c. 1980s–1990s) ■ Description An exceptionally grand and meticulously decorated white porcelain freshwater jar, known as a Mizusashi (水指), crafted by the highly celebrated Korean master potter Lee Eun-koo (李殷九). Dating from the late Showa to early Heisei period (circa 1980s–1990s), this museum-grade vessel captures the precise formal elegance of early Joseon-dynasty royal court white ceramics. The entire surface of the robust, wide-bodied jar and its matching fitted lid is processed using the demanding ""Sgraffito"" (掻落 / Kakiotoshi) technique. After coating the iron-rich clay body with a dense layer of fine white porcelain slip, Master Lee delicately carved away the negative space by hand before firing. This reveals the darker contrasting under-clay, creating a breathtaking, relief-like tapestry of continuous Peony Blossoms and Vines (牡丹文). The neck rim is anchored by an elegant geometric key-fret border. Accompanied by its original premium paulownia wooden presentation box (Tomobako) hand-signed ""Lee Eun-koo Zo"" (李殷九 作) and struck with his official vermilion seals, the interior basin remains impeccably glazed in a smooth brown-iron slip. This monumental vessel represents an elite crossover piece for collectors of advanced East Asian studio pottery and high-tier tea ceremony utensils. ■ Highlights Masterwork by Lee Eun-koo: Features the genuine hand-written signature and verified stamps of one of Korea's most historically prominent revival ceramic titans.
