Chinese Northern Song (960-1127) dynasty qingbai (yingqing) porcelain glazed bowl with relatively straight sides and slightly flared rim decorated on the interior with combed abstract swirling floral patterns. The smooth, thin, crackled olive-green glaze pools in the center and accumulates at the exterior foot. The low foot is unglazed, revealing a gray-white body. 10th/11th century. 7” diameter x 2 3/8” high. Very good overall condition. This bowl is from a Phoenix, Arizona collection.
