that even the bird and fish forms may have been roughly designed in the colouring medium. Plate 17 will serve to illustrate this group of possible Kuan wares. Another example is a dish in the British Museum which has a whitish porcellanous body and a slightly crackled pale lavender grey glaze of singular beauty. Other specimens in the same collection include a small tea bowl with misty grey glaze of the _fên ch´ing_ type, smooth and uncrackled, and a body which appears deep reddish brown at the foot; and a small bottle-shaped vase, with lobed body of melon shape, which, though of doubtful antiquity, answers closely to the Chinese descriptions. It has a dark-coloured but well levigated body, deep brown at the foot, and showing a brown tinge where the glaze has run thin at the lip, and the colour is a pale bluish grey with rosy tinges where the body colour is able to penetrate the semi-translucent glaze. Another doubtful specimen, with very similar characteristics, was figured by me in the _Burlington Magazine_ some years ago.[130] Since the genuine Sung specimens were sent to the Imperial factories to be closely copied (about 1730), it might be supposed that the relatively modern imitations would supply some clue to the original types. There are one or two examples of eighteenth-century copies of Kuan ware in the British Museum on which the glaze is definitely lavender blue in tint, with a crackle which in one case is wide and emphasised by blackened lines, and in the other of a finer mesh.[131] The natural tendency, however, of modern imitative wares is to exaggerate some characteristic which this or that potter might imagine to be specially important, and as it is impossible to say in many cases exactly when the piece in question was made, we cannot be sure how far the potters in each case may have strayed from the original type.[132] No doubt in time these imitations would become a mere convention. It should be said in passing that the modern copies have a white porcelain body, and to obtain the appearance of "brown mouth and iron foot" the potters had recourse to the expedient of colouring the parts concerned with brown ferruginous clay.
