Massive Chinese Jin to Yuan dynasty (12th/13th century) Henan dark brown/black glazed horizontally ribbed ovoid form stoneware jar with high, wide shoulders narrowing at the base. The thick glaze drips down toward the flat, unglazed base. The rich black/brown glaze, referred to as “temmoku” by the Japanese, is highlighted by a russet colored cylindrical neck and rim. Measures about 13” high x 13 1/2” diameter. Very good overall condition with typical surface scratches to the glaze.
