To an early period, also, belongs the ware decorated in black (or less often in lilac), with figures and landscapes, ‘transferred’ by a variety of ingenious processes, which we need not describe here, from an engraved copper-plate. Used before this time on enamels at Battersea and on earthenware at Liverpool, it was with the ‘jet enamelled’ ware of Worcester, printed from the plates specially made for the purpose by Robert Hancock (who had previously been employed at Battersea under the Frenchman Ravenet), that the new process was above all associated. Here, for the first time perhaps in its history, porcelain was ‘made to speak,’ to use Napoleon’s phrase. On it the hero of the day was immortalised: in 1757 we find Frederick the Great, crowned by a winged Genius; at a later time the Marquis of Granby and the elder Pitt. It is Hancock, it would seem, that we must regard as the _capo scuola_ of another ‘school of decoration,’ one which, spreading at a later time to Staffordshire, has been carried to all parts of the world where transfer-printed English crockery has penetrated. The basis of this decoration is a classical ruin--generally a fragment of the entablature of a Roman temple supported on a few columns; add to this a pointed building something between an obelisk and a pyramid,[240] the whole enclosed in a framework of conventional trees. Upon how many millions of jugs and basins was this pattern repeated, in black, in green, and in lilac! At some future day, by the study of potsherds so decorated collected in many lands, an archæologist may be able to trace the course of English commerce in the nineteenth century, and to draw strange inferences as to the state of the arts at that time in our country. This ‘jet-enamelled’ transfer was printed over the glaze; sometimes, to enliven the effect, other colours, painted by hand, were added, with disastrous results. In the blue and white printed ware, on the other hand, the cobalt pigment is applied under the glaze. The paste of this transfer-printed porcelain is often of good quality and very translucent, and the finer earlier specimens are much sought after by collectors. We have seen that at least from the _cultur-historisch_ point of view this printed china is not without interest.
