Whether we consider the cobalt blue as a colour, as in the celebrated ginger jar with prunus flowers sold at Christie's for 5,900 guineas, or such pieces as we show in our illustration from Mr. Duveen's collection, worth £2,000 each, from 1720 right down to our own times this ware has been copied and ever recopied, but there is something in the blue used for decoration, something, too, in the quality of the white porcelain itself, and again something in the glaze, an intense brilliancy. These furnish a combination which has never been rivalled.
The Kang-he period was noted for a very rare biscuit Celadon, in which the surface of the panels in relief is unglazed, though the remainder of the decoration is blue under the glaze. Another fine quality of porcelain was that with archaic decoration having conventional flowers and bands in black and green. The marks of the Kang-he period vary. In the earlier part of his reign the double blue circle and the Kang-he _nien-hao_ are frequent, but collectors must note that many specimens of this period have no date mark at all. If the two blue rings are used there are no letters inside. The reason of this is rather curious. In 1677 the superintendent of the works gave an order to the factories at King-te-chin, in which he forbade the inscription of the Emperor's name or the characters which gave the history of their sacred great men. This order was given because it was thought that if the porcelain was broken it would be reflecting upon the honour of the Emperor or of these sanctified persons who were represented not alone by inscriptions, but by paintings used in the decoration. However, this law did not remain in force for a very long period. When a piece is found with empty rings or with the symbol marks of the fungus leaf, &c., it can be assigned to a few years later than 1677. The importation to Europe had reached considerable dimensions before this.
We read that in 1664 nearly 50,000 pieces of rare Japanese china were imported into Holland and about 17,000 more of various kinds from Batavia by the Dutch East India Company. In this connection the rivalry between the Dutch and the Portuguese must be noted, because it affected the Oriental trade in porcelain very considerably. Stirred up by the Dutch, the Japanese, in 1640, excited by their fears of the ultimate designs of the Portuguese and the Spaniards, who had later appeared upon the scene, banished them in favour of the Dutch. Some thousands of Christian converts were massacred, and the Dutch were fully established at Nagasaki, where they laid the foundation of that progress towards Western civilisation to which the world, and especially Japan, owes so much.
