Speckle-glazed Ewer with Double Rings

An ewer is an ancient wine vessel other than a teapot, and was developed from the ewer with chicken-head spout or dish-shaped mouth. Speckle-glaze was a new creation during the Tang dynasty. Two metal oxides were used as colorants of the glaze. The raw body would be glazed twice and fired at high temperatures. The result vessel showed splendid colors like colorful clouds. This ewer has fascinating glaze patterns: blue speckles scattered on the black glaze surface.
