The company specialised in "Brown Betty" teapots. Early versions were made with Terracotta clay and a transparent glaze, using the jigger and jolley method, later they were slipcast from white earthenware clay and glazed with a Rockingham brown glaze. They began making novelty shaped teapots in the 1930's Crinoline ladies, a father Christmas teapot and in 1938 the iconic racing car teapot, followed by a tank with "Old Bill" as the lid in 1947.
