The technique of luster decorated pottery combines silver and copper oxides with sulfur and other materials, which are applied in liquefied form to the surface of a previously glazed and fired object. The ware is then refired in a muffled, or reducing, kiln, so that the oxygen is drawn out from the metal oxides, producing a dazzling metallic surface.
