It is not unlikely that in China the Western influence did not make much way until the time of the early Ming emperors, and that it was due more immediately to the growing commercial intercourse with the Persian Gulf, but this intercourse was itself fostered by the events of the Mongol invasion.
There is very little to be said of the porcelain made during the time of the MONGOL or YUAN dynasty, and we have few specimens that can be definitely assigned to that period. The name is still given in Pekin to a rude, somewhat heavy ware, with a thick glaze of mingled tints, among which a shade of lavender with speckles of red predominates. This is but a modification of the Chün yao of Sung times, and belongs in a general way to the class of ‘transmutation’ wares--those in which the colours depend on the partial reduction of the oxides of iron and copper in the glaze. Specimens of this ware that claim to be of Chinese origin are often found in Japan, where they are much in favour for use as flower vases, but neither in that country nor in China have the pieces we meet with much claim to any great antiquity.
There is only one specimen in the Bushell manuscript that is attributed by Tzu-ching to the Yuan period--this is a little vase of white ware decorated with dragons faintly engraved in the paste under the glaze.
This white ware, generally classed as Ting, is indeed in many of our books on porcelain considered to be especially characteristic of the Mongol dynasty, but I cannot find any definite confirmation of this. The finer pieces of plain white seem to be generally attributed by the Chinese rather to the beginning of the next dynasty. The little white plate in the Dresden Museum, said to have been ‘brought back from the East by a crusader,’ has no claim to such an early date.[39]
It was in the course of the three centuries during which the Ming dynasty ruled in China that the greatest advance was made in the manufacture of porcelain. When, however, we come to look a little more closely, we find that this long period may be shortened by nearly a hundred years. Before the accession of Yung-lo (1402), and after the death of Wanli (1619), the times were little favourable to the arts of peace, and even in this shorter period of two centuries there were intervals, indeed whole reigns, of which there is little to report.
