Description:
English slipware dish, made at the Isleworth China Works, Isleworth - a part of West London, England, ca. 1780. Oval molded baking dish decorated with stripes or trails of white and dark brown slips in a marbleized pattern. The reverse of the dish is undecorated and unglazed. Before placing the clay bat on the mold for shaping, the flat sheet of clay was decorated with a layer of white slip (which appears yellow because of the iron in the lead glaze) and dark iron rich slip. These slip trails were manipulated to create the marbleized appearance. The oval baking dish was then molded over a drape or hump mold. The edge has been coggled. This example has an impressed mark which appears like a large '1' next to what looks like an inverted '7' with an angled line over a '2'.
Label Text:
The Isleworth China Works was established by Joseph Shore who came to Isleworth, possibly from Worcester, in 1757. As well as making porcelain, this manufactory also made cream-colored earthenware and slipware. Joseph Shore's daughters Ann and Mary married Bristol delftware potters Benjamin Quarman and Richard Goulding who both came to Isleworth. The factory remained in the Shore, Quarman and Goulding families until its closure in 1831. Joanna Goulding then relocated the factory to a site in Hounslow where production of slipware and flowerpots continued until 1855. The rediscovery of the Isleworth factory resulted from archaeology in 1998 which was followed later by further work at a site to which the factory moved. Utlitarian slipware had the longest period of production and perhaps was the foundation of their success. Isleworth slipware is characterized by an unglazed, undecorated underside which is typically pink in appearance. Some Isleworth slipware have impressed numerals (1, 1 1/2, 2) which may refer to size or volume. The dish can be attributed to the Isleworth China Works, Isleworth, West London, c. 1780. According to Isleworth scholar Raymond Howard, this example has an impressed mark which appears like a large '1' next to what looks like an inverted '7' with an angled line over a '2'. The purpose of the marks is not known. A similar baking dish is illustrated in "Isleworth Pottery and Porcelain recent discoveries" 2003 exh. cat. by Roger Massey, Jacqueline Pearce and Ray Howard, p. 93, fig. 145.
