The Italian writer Passeri states that the tin-glazed ware or true maiolica was made at Pesaro in 1500, and that the process was introduced from Tuscany. A better ground for the reception of the colours used in the decoration was afforded by the new enamel, but it did not entirely supersede the manufacture of the mezza-maiolica, as a great deal of the latter ware still continued to be made of a brilliant metallic lustre at the fabriques of Pesaro and Gubbio. At Castel-Durante, Urbino, and Diruta were other famous botegas or fabriques where the lustred ware was made, but none were so celebrated as that of Maestro Giorgio at Gubbio. It was at this famous botega that the best of all the golden and ruby metallic lustres were produced. The ruby lustre particularly seemed to be a monopoly of the Gubbio workshops, for it is known that many of the Italian factories sent their pieces to Maestro Giorgio at Gubbio to have the ruby and the gold lustre added as a finish to parts of the designs. Maiolica was made at Venice in the sixteenth century, also at Forli, Diruta, Siena, Caffaggiolo, and Faenza, where much early work of great beauty in design was produced. We shall only have space to describe a few of the most important products of Italian maiolica. [Illustration: Fig. 16.—Pitcher; Caffaggiolo Maiolica. (S.K.M.)] An early method of decorating maiolica pottery is known as “sgraffitto-work,” in which the patterns are scratched or incised into the ground: this was a favourite method of executing outdoor plaster decoration in Italy. It consists in laying on a ground of coloured clay or plaster on another coating of a different colour, and while this second coating is moderately soft, the pattern or design is incised or “scratched” down to the first coating or ground, which, being of a different colour, reveals itself, and thus forms the pattern. In both, pottery and plaster decoration sgraffitto work is usually accompanied by modelling in relief, such as representations of leaves, flowers, and fruit in bas-relief bands, or medallions of figures and animals, in high relief. After the ware is incised it is glazed with a translucent lead glaze, variegated with green and yellow colouring over the white engobe (Fig. 17). The sgraffitto pottery of Italy is either of Lombardic or Venetian origin, as appears from the usual Gothic character of the designs. [Illustration: Fig. 17.—Sgraffitto Maiolica. (S.K.M.)] The wares of Caffaggiolo are distinguished by a purely white glaze, with masses of a rich cobalt blue used as portions of the groundwork for the ornament; sometimes green and purple are used with the blue, and at other times a bright orange yellow and a copper green or an Indian red. Caffaggiolo, Faenza, and Forli wares have much resemblance to each other. The pitcher (Fig. 16), with the arms of the Medici family, belongs probably to the Caffaggiolo school, and is a work of the early years of the sixteenth century.
