See Ralph and Terry Kovel, Kovels' American Pottery: The Collector's Guide to Makers, Marks, and Factory Histories, p. 189 for quotations from Rookwood catalogs of 1896, c. 1902. 1904, c. 1915, and from advertisements, on the various Rookwood glazes. The sea green glaze, which was introduced in 1894, is described as: "a variety of Rookwood in which a limpid, opalescent sea-green effect is attained. Beautiful combinations of rich, deep blues, and greens, relieved with glowing touches of golden yellow, red and other warm colors marked this variety."
According to a 1902 promotional brochure, entitled Rookwood Pottery (p. 36), "metals applied appropriately to reliefs modeled by artists in connection with painted decorations characterize another type of Rookwood. This method gives the piece a variety and richness of texture and color, while retaining the unity of design usually lost in metal mounting." Rookwood Pottery developed the electrodeposit method of metal mounting during 1899 and introduced it to the public at the 1900 Exposition Universelle in Paris. After a piece was thrown, the area in relief, to be electroplated, was left dry and unglazed for the metal mount. Upon completion of the final clay firing, the area was coated with either silver or copper by the electrodeposit technique.
