9.5 in diameter. This pair of antique hot water warming plates consists of ceramic plates set into deep metal bases. These utilitarian items were designed to be filled with hot water through a side spout to keep food warm during service. The ceramic inserts feature underglaze transfer-printed floral decorations. The first plate features an underglaze blue floral pattern with a central medallion and scrolled borders. The second plate features a pink or red floral transfer decoration with an intricate foliate border. Both ceramic plates are mounted into basin-like metal housings, likely constructed from tinned copper or pewter. Each housing is equipped with two looped side handles and a cylindrical fill spout. The blue plate includes a brass screw-on cap for its spout. No maker marks or factory stamps are visible on the ceramic or metal components.
