The Zun has a spreading mouth, a short neck, a broad shoulder from which the body tapers to a slightly spreading base. The snow-flake blue glaze with gold tracery on the body is made in the technique of soufflé glaze. The glaze is covered with uniform speckled blue spots, from which the white glaze background is slightly revealed. The gold tracery decorated on the blue glaze include S-shaped cloud pattern, ball pattern, lotus pattern and sea wave pattern. The coloring is fine and the work is delicate.
