Coming in the same period as the three Kang-he enamel colours are the two underground glaze grounds powder-blue and coral-red. True powder-blue is Kang-he, but it has been copied, and badly, right on to our own times, whilst in coral red--"_rouge de fer_"--the later Keen-lung specimens can fairly be said to rival those of the earlier period. It is doubtful whether this rivalry would apply to any other class of porcelain.
_A._--THE BLACK FAMILY--"_FAMILLE NOIR_."
This magnificent production, of which we give examples in our illustrations, is usually ascribed to Kang-he, possibly it may be earlier. Its characteristic quality was a black ground covered with almost invisible green glaze. The body of these pieces was decorated with flowers in yellow, green, and white, and with butterflies. A common form of decoration--if any can be called common in dealing with such a rare product--was that the panels were decorated with emblems of the seasons. A tree of peony with green, white, and grey blossoms appears to us to be fantastic, but the peony in China grew to the height of 12 ft. The chrysanthemum with flowers of similar colours formed a second panel, the guelder rose with green and white blossoms made the third, whilst the fourth had the lotus flower with tall green and grey flowers growing at the foot of green rocks at the edge of a green lake. The prunus blossom in white or pale green was often used for floral decoration, and yellow finches with green wings, white storks, white butterflies and bees are often found. So, too, is a green-faced dragon with a long brilliant green body in coils, sporting itself in mid-air. Reference to our illustrations will bring out other forms of decoration treated at some length.
[Illustration: BLACK FAMILY--"FAMILLE NOIRE."
This rare class, which is well exemplified by the fine specimens in the Salting Collection in the Museum at South Kensington, seems to have had the decoration applied in outline or in colour to white porcelain, and then the black ground was filled in. The black is thin and the tint is not intense. The decoration may be left white, or "_famille verte_" or "_famille rose_," &c. In these respects it differs from the modern ware, in which the enamel is thick, and the painting of the flowers and insects is far from being brilliant. Such pieces have no value.
