The brown and black was supplemented, in the Ming period if not earlier, first by a maroon slip and later by iron red and green enamel.[238] A specimen with panelled decoration in these colours was described by Brinkley[239] as having been preserved in Japan since 1598, showing that this class of decoration was at any rate contemporary with the "red and green family" of porcelain. A specimen in the Benson Collection shows, further, that aubergine and green were sometimes used in combination with turquoise glaze, as in the Ming "three-colour porcelain." Under-glaze blue is also found on Tz´ŭ Chou wares, but we have no clue to the date when it was introduced. The ordinary ware, made in quite modern times at Tz´ŭ Chou, is illustrated by a small flask and a figure obtained by Dr. Bushell, and now in the British Museum. Though decorated in the characteristic style with slight sketchy design in brown and maroon, they show a decided falling off when compared with the older specimens. The body is a hard, greyish white stoneware; there is no slip covering, and the glaze is yellowish, soft-looking, and freely crackled, without the solid qualities of the older ivory glaze on a white slip coating. I am inclined to think that this degenerate type of ware dates back no farther than the nineteenth century, and that the Tz´ŭ Chou pottery preserved its character up to and perhaps throughout the eighteenth century. There are several examples of pottery pillows, with body and glaze of good quality and finely painted in black and brown, with panelled designs sometimes containing floral motives, sometimes figure subjects. One of these, exhibited at the Burlington Fine Arts Club in 1910,[240] was tentatively ascribed to the late Ming period. Since then the British Museum has acquired another, and I have heard of two more in private hands. The three last bear the mark of a potter named Chang,[241] and on some of them we find additional inscriptions containing the words _ku hsiang_ (of old Hsiang) and _hsiang ti_ (of the region of Hsiang). Hsiang, I find, is the old name of Chang-tê Fu, the prefecture in which Tz´ŭ Chou is situated, and this fact definitely connects the ware with the factories under discussion. At the same time the relatively large number of these pieces in our collections and the style of Chang's mark seem to indicate that they are of fairly recent date, probably not older than the seventeenth century.
