From the foregoing considerations we may conclude that the Ju porcelain was a beautiful ware of celadon type, varying in tint from a very pale green to a bluish green.
Though it is nowhere definitely stated how long the Ju Chou factories retained their supremacy, it is tolerably clear from Hsü Ching's reference in 1125, or very soon after, to the "modern porcelain of Ju Chou," that they came into prominence towards the end of the Northern Sung period, perhaps in the last half of the eleventh century; and as we have no further information about them, we may perhaps infer that they sank into obscurity when the Sung emperors were driven from the North of China by the invading Tartars in 1127. In any case, the Ju ware seems to have become as extinct as the Ch´ai by the end of the Ming dynasty. Hsiang Yüan–p´ien, late in the sixteenth century, states that "Ju yao vessels are disappearing. The very few which exist are almost all dishes, cups, and the like, and many of these are damaged and imperfect."[106] A few years later another writer[107] declares that the Ch´ai and Ju porcelains had ceased to exist.
It is not to be supposed that Ju Chou had the monopoly of the particular kind of ch´ing ware in which its factories excelled. A number of other and not distant potteries were engaged in a similar manufacture, though with less conspicuous success. We read,[108] for instance, that "it was made in the districts of T´ang, Têng, and Yao on the north of the (Yellow) River, though the productions of Ju Chou were the best."
It has been already remarked that we possess no authenticated example of Ju porcelain. Doubtless there are many pieces which are tentatively assigned to Ju Chou by hopeful owners. But it must be confessed that the few which have hitherto been published as such are singularly unfortunate choices. Dr. B. Laufer, for instance, in his excellent work on jade,[109] incidentally figures two vases for divining rods of a well–known form, of which he hazards the remark "that both have presumably been made in the kilns of Ju–chou."
Dr. Laufer does not claim to have made a particular study of Chinese ceramics apart from the Han pottery, but if these pieces are Ju yao, then Ju yao, so far from having been extinct for some centuries, is a comparatively common ware. Another instance is the "funeral vase," now in the Victoria and Albert Museum, published[110] by its former owner, Dr. Bushell, as a specimen of Ju ware, mainly, I suppose, on the strength of the description, "Kuan Yin vase of Ju Yao," engraved on the stand by the Chinese collector[111] through whose hands it had previously passed. This form of certificate is always open to doubt, and had it really been a specimen of undoubted Ju yao, it is most improbable that the Chinese would have allowed it at that time to pass into foreign hands.
But a glance at the piece itself is sufficient to dispel all illusions on that point. So far from excelling other Sung wares, this piece is decidedly inferior in every detail to the most ordinary Sung specimens. It has a coarse, sandy, greyish buff body and impure greyish green tinge, such as appears on some of the early funeral wares which make no pretence to finished workmanship. The ornament consists of applied reliefs perfunctorily moulded, and though its archæological interest is considerable, and, like almost all Chinese wares, it possesses a certain charm, any attempt to place it on a high artistic plane can only end in a reductio ad absurdum.
Many other examples of this ware have since arrived in Europe, and they all belong to the same type. Some, however, appear to be later than the others, having reliefs of white porcelain instead of the usual pottery. They are always described as "funeral vases" by the Chinese, and it is exceedingly probable that the description is correct. The subjects of the reliefs are always of a hieratic kind, including such figures as the dragon of the East, the tiger of the West, the tortoise of the North, and the red bird of the South, the sun disc, and a ring of indistinguishable figures, perhaps Buddhist deities. There is no reason why such a type of sepulchral vase may not have been in use for many centuries, and if the porcelain reliefs in one specimen suggest a date no earlier than the Ming dynasty, the glaze in another has strong analogies to some of the rougher T´ang wares. The majority of these vases are of coarse, rough make; others are superior in finish and of comparatively attractive form. A good example, belonging to Mr. R.H. Benson, is shown on Plate 14. It is of dense grey stoneware, with opaque greenish grey glaze, with a balustrade supported by four figures on the shoulder, and a dragon and a figure on a tiger (perhaps representing the mythical Fêng Kan), besides some small figures with indistinct attributes on the neck. The height is 20 inches.
It is, of course, possible that some of these represent the coarser makes of the T´ang, Têng, and Yao districts (see p. 55), and that the attribution of the Bushell vase by Liu Yen–t´ing may refer to a lower quality of Ju yao which included these wares, or may be even the wares made at Ju Chou before or after its period of Imperial patronage.[112]
My own conception of the Ju yao is most nearly realised by the lovely but sadly damaged bowl in the Alexander Collection lately in the Loan Court at the Victoria and Albert Museum. Its peculiar form is difficult to reproduce by photographic means, but Fig. 1 of Plate 16 gives a fair idea of it. The colour is precisely that of the most beautiful bluish green Corean bowls, but the usual Corean finish and the sand marks on the base are absent, and the glaze is broken by a large, irregular crackle. Surely this cannot be far removed from the "secret colour" of the Yüeh ware and the fên ch´ing of the Ju?
