The term ‘rice-grain’ was originally applied to the open-work diapers filled in with glaze. As a whole this kind of work may be referred to the later part of the reign of Kien-lung, and especially to that of his successor, Kia-king (1795-1820), so that it is not unlikely that the Persian frit-ware, some of which is of earlier date, may have served as a model.
Blue and White Ware.—This is, on the whole, the most important as well as the best defined class of Chinese porcelain. The Chinese name, Ching hua pai ti (literally ‘blue flowers white ground‘), defines its nature well enough.
We have no information as to the origin and development of blue and white porcelain in China, nor indeed do I know of any collection where an attempt has been made to classify the vast material. We must here content ourselves with a few notes which at best may indicate the ground on which such a classification should be made. We have seen ([p. page 75]) that there is at least some presumptive evidence that the Chinese may have derived their knowledge of the use of cobalt (as a material to decorate the ground of their porcelain) from Western Asia, at a time when both China and Persia were governed by one family of Mongol khans. For we know now that in Syria or in Persia, in the twelfth or early in the thirteenth century, a rough but artistic ware was painted with a hasty decoration of cobalt blue and covered with a thick alkaline glaze; while in China, at that time, we have no evidence for the existence of any porcelain other than monochrome.
It is possible that the earliest Chinese type of the under-glaze blue may be found in certain thick brownish crackle ware, decorated under the glaze, in blue, with a few strokes of the brush. Plates and dishes of this kind have been found in Borneo, associated with early types of celadon.[97] A similar ware, not necessarily of great antiquity, is often found in common use in the north of China and, I think, in Korea, and with it we may perhaps associate the greyish-yellow Ko yao decorated with patches of blue and white slip.
It is very likely that there would be a strong opposition on the part of the Chinese literati to such a novel and exotic mode of decoration, but that such opposition would be less felt in the case of ware made for exportation, or it may be for use among the less conservative Mongols. We have an instance of a similar feeling in the protest that we know was made some two or three hundred years later against the application of coloured enamels to the surface of porcelain.
Of the thousands of specimens of blue and white porcelain in our collections there is probably no single piece for which we can claim a date earlier than the fifteenth century. We can, however, distinguish two

types among the examples, which for the reasons given on page 83 we may safely assign to the Ming period. The first is distinguished by a pure but pale blue, and the design (generally somewhat sparingly applied) is carefully drawn with a fine brush. This, it would seem, was the ware imitated by the Japanese at the princely kilns of Mikawaji. The other type is distinguished by the depth and brilliancy of its colour, the true sapphire tint, differing from the later blue of the eighteenth century, in which there is always a purplish tendency. There are some good specimens of this type in the British Museum, but we will take as our standard a jar at South Kensington about twelve inches in height ([Pl. xix].). The remarkable thickness of the paste in this vase shown in the neck, which has at some time been cut down, the marks of the junction of the moulded pieces of which it was built up, the slight patina developed in the surface of the glaze, are all signs that point to an early origin. But what is above all noticeable is the jewel-like brilliancy of the blue pigment with which the decoration—a design of kilin sporting under pine-trees—is painted.
