Steatite was sometimes mixed with the glaze, and had the same effect as a sudden immersion. It would naturally follow that no such ornamentation could be applied to porcelain, the paste and glaze being too closely allied in composition. To surmount this difficulty, the glaze was combined with materials destructive of its close affinity with the kaolinic paste. A simultaneous shrinkage being thus made impossible, the glaze cracked. Although both Chinese and foreigners place a high value upon good specimens of crackle, admiration of such a style of ornament involves a decided perversion of taste. It is safe to say that nine persons out of ten would, if left to exert their own uninfluenced judgment, condemn a crackle vase as devoid of all pretension to ornament. It is when we find that the deformity is the result of design, that the piece is a curiosity of workmanship, and represents the mechanical ingenuity of the potter, that it becomes an object of interest and a desirable possession. Crackle-ware has been made by the Chinese since the Song Dynasty, which extended from A.D. 960 to 1279, and probably from a much earlier date. Ornamentation is sometimes laid above the glaze. One very old style of decoration in relief upon the crackle (Fig. 70) consists of medallions and bands of a brown paste, of which imitations, having lions’ heads holding rings in the centre of the medallions, are abundant. Pottery is used by the Chinese in the making of household vessels and utensils of all kinds--as extensively, in fact, as by the Egyptians. They have earthen-ware reservoirs and basins, lamps, cooking-pots, water-filterers, teapots, and toys. Ornamental vases are also made of earthen-ware, and some specimens show that the Chinese lavished upon their comparatively humble wares--according to our ideas--ornamentation as beautiful and elaborate as that upon porcelain.
