Among the Sung wares many of the white Ting specimens are found to be translucent in their thinner parts, and these may be fairly regarded as porcelain proper. A considerable number of other white porcelains have come over of late under the description of Sung wares, and many of them are certainly early enough in form and style to belong to that period. They are true hard porcelain, translucent, and of a creamy white colour. Being for the most part without decoration, they can only be judged by their forms, and in view of the conservative habits of the Chinese, it would be rash to assert too emphatically their Sung origin. Yüan and even early Ming dates are suggested by the more cautious critics; but the possibility of a Sung origin having been established, I am inclined to give the evidence of form its full weight. There are, besides these, other well-defined types of translucent porcelain which may confidently be attributed to a period as early as the Sung, but here the possibility--nay, probability--of a Corean origin has to be considered. It is certain that many of them have been found in Corean tombs; the provenance of the rest is doubtful. One type is a delicious smooth white porcelain with glaze of faintly bluish tinge, highly translucent, and worked very thin at the edges. The base of the vessels (usually small shallow bowls or saucers) is unglazed, and shows a soft-looking sugary body of close texture, rather earthy than glassy, and slightly browned by the fire. They have, in fact, almost the appearance of a "soft-paste" porcelain like that of Chelsea. These are so different from any known Chinese type that I strongly incline to a Corean origin for them. Another type is of hard but translucent ware with glaze of distinctly bluish tinge. A bowl in the British Museum is a good example of this. Of the usual conical form, it has a plain outside, and the inside is decorated with an incised design of not very clear meaning, but apparently a close foliage ground with highly formalised figures of boys. If this interpretation is correct, it is a conventional rendering of the well-known pattern of boys in foliage, Chinese in origin, but frequently used by the Corean potters. The design ends in Corean fashion, about an inch below the rim, leaving a plain band above it. The glaze is a faint bluish colour all over, and is powdered with specks, a fault in the firing; the base is almost entirely unglazed, and the biscuit, where exposed, has turned reddish brown. The style of this piece is strongly Corean. The same peculiarities in the base are shared by another type of small bowl, usually decorated inside with a sketchy design in combed lines. Some of these are creamy white; others are bluish white with a decided blue tinge in the well of the bowl where the glaze has formed thickly.[322] Another group, which is also said to be represented among the Corean tomb wares, is practically indistinguishable from the creamy white Ting Chou porcelain.
