Although not belonging to the same family, we may here refer to a rare vase (Fig. 89), which supplies us with a remarkably fine specimen of a kindred style of ornamentation. In this case the ground is black, and the “hawthorn,” or plum-tree, sprays, with white flowers, are wreathed gracefully over its surface. The green of the leaves would lead us to class it with the Green family. The piece is, however, exceptional, since black is, as a rule, seldom introduced to any great extent in decoration. To what fabric or age shall we attribute it? It is possibly a specimen of the skill of Thang-kong, who lived between 1736 and 1795, and was director of the Imperial works. Thang not only reproduced some of the ancient colors, such as the dark-blue and red, but gave full sway to his own inventive genius. Among his original works are a purple, a black enamel, and a black enamel with white flowers, which suits the description of the unique specimen referred to. It is, in any event, by reason both of its graceful shape and decoration, deserving of attention. [Illustration: Fig. 89.--Chinese Porcelain. White “Hawthorn” on Black. (S. P. Avery Coll., N. Y. Metropolitan Museum.)] To return to the blue-and-white, there are specimens, generally plaques, with flowers resembling asters, painted in blue (Fig. 90). One has some difficulty in bringing the formal arrangement of these flowers into accord with Chinese art as we find it elsewhere. The flowers are regularly disposed in the centre of the plaques, and repeated, in smaller size, in a single row round the rim. It seems more than probable that the style is borrowed or slightly modified, and one is strengthened in such a supposition by the fact that it is seldom, if ever, found upon pieces as pure in paste as the average Chinese porcelain. Possibly, with the intention of following his model more closely, the Chinese artist designedly resorted to an inferior body, such as might have reached China from Persia.
