CHÜN YAO.--It is to this ware that we may trace back the now famous family of _flambé_ porcelain. Chün yao was already made in early Sung times, _i.e._ before the Mongol conquests of the twelfth century, in Honan, not far from the old capital of Kai-feng Fu. A description in a work of the seventeenth century leaves no doubt as to its identification. ‘As to this Chün yao,’ the writer says, ‘a fine specimen should be red as cinnabar, green as onion-leaves or the plumage of the kingfisher, and purple, brown, and black like the skin of the egg-plant.’ We have here the description of that ‘transmutation’ or _flambé_ ware of which such magnificent examples were made at King-te-chen in the seventeenth and eighteenth centuries, and which has lately been successfully imitated in France. The play of flashing colour in the glaze was said to have been originally the result of accident, but we must not attach much importance to statements of this kind. In the old Sung pieces the clay is less white and fine than in the highly finished examples made at King-te-chen during the reigns of Kang-he and Yung-cheng. On the Sung ware we may frequently find a number (from one to nine) engraved, sometimes more than once, in the paste, and these characters are carefully copied in the later reproductions. We have here perhaps the earliest instance of the employment of a mark on porcelain. The old writers tell us apologetically of the vulgar names given, by way of joke, it would seem, to these glazes, such as mule’s lungs or pig’s liver--no inapt comparisons, however, for some of the effects seen in these old wares. These varied hues were of course obtained from copper in the first place, though the presence of iron, in both stages of oxidation, may sometimes add to the variety of the tints. KIEN YAO.--This was a dark-coloured ware made at Kien-chou, north-west of the port of Fuchou. It must not be confused with the well-known creamy-white ware of Fukien, exported in later days from the same port. Certain shallow conical cups of this ware, with a vitreous glaze, almost black, but relieved around the margin with small streaks and spots of a lighter colour, were especially valued from very early times for the preparation of powdered tea--nowhere more than in Japan, where an undoubted specimen of this Kien ware is treasured as a priceless heirloom. There is an excellent specimen in the British Museum: a careful examination of this little bowl will give no little aid in understanding what are some of the qualities that are looked for in China and Japan in these old glazes. There is a quiet charm in the glassy surface, and an air as of some quaint natural stone carefully carved and polished rather than of a product of the potter’s wheel.
