Two interesting ewers in the Dresden collection (Figs. 1 and 2 of Plate 71) probably belong to this period, or at any rate to the sixteenth century. They are fantastically shaped to represent a phœnix and a lobster, and are decorated with green, yellow, aubergine and a little turquoise applied direct to the biscuit. Parts of the surface have been lightly coated with gilding, which has almost entirely disappeared. These pieces are mentioned in an inventory of 1640, and a lobster ewer precisely similar was included in the collection made by Philipp Hainhofer in the early years of the seventeenth century.[134] Among the examples of on-glaze enamels of this period are those in which the coral red derived from iron oxide (_fan hung_) is the most conspicuous colour. This red is often highly iridescent, displaying soft ruby reflections like Persian lustre; at other times it is richly fluxed, and has a peculiarly vitreous and almost sticky appearance. The former effect is well seen in a small saucer in the British Museum, which has a wide border of deep lustrous red surrounding a medallion with lions and a brocade ball in green. The latter is seen on a square, covered vase in the same case, decorated on each side with full-faced dragons in red and the usual cloud accessories in inconspicuous touches of green and yellow. The yellow enamel of the period is often of an impure, brownish tint and rather thickly applied, but these peculiarities of both yellow and red continued in the Wan Li period.

Diameter 8 inches. _Alexander Collection._ Fig. 2 with phœnixes (_fêng-huang_) flying among scrolls of _mu-tan_ peony. Diameter 7 inches. _Cumberbatch Collection._] The combination of enamel colours with underglaze blue, which was so largely used in the Wan Li period as to be generally known by the name _Wan li wu ts’ai_ (Wan Li polychrome), is not unknown on Chia Ching wares. The wide-mouthed jar, for instance, from the collection of Mr. S. E. Kennedy[135] (Plate 69, Fig. 2) is decorated with a design of fish among water plants in deep Chia Ching blue combined with green, yellow and iron red enamels; and a small bottle-shaped vase in the British Museum has the same blue combined with on-glaze red, green, yellow and aubergine, the design being fish, waves, and water plants. The greens of this and the Wan Li period include various shades--bright leaf green, pale emerald, and a bluish green[136] which seems to be peculiar to the late Ming period.
