Porcelain. Dillon Edward
of China, some such kaolinic pottery may have been made by the Chinese from very early times. When in Tang or in earlier days it occurred to them to attempt to imitate jade or other natural stones, they had the good fortune to be already using materials that allowed of these experiments being after a time crowned with success. The important point that still remains unsettled is at what date they first succeeded in covering a ware of this class with a vitreous coating. For the date of the first use of glaze in China we can at present only give a very wide limit, let us say some time between the first and the fifth century of our era. Very probably it was their acquaintance with the nature of glass that put them on the right track. This material, it is said, they first knew of from their intercourse with the later Roman empire. There is some reason to believe that they acquired at the same time the secret of its manufacture, though, according to the Chinese, the art was lost at a later time.34
We can now form some idea of how far the art of making porcelain had advanced at the time when the tide of the Mongol invasion swept over the country. Our knowledge of the wares made at this time must be derived chiefly from the imitations of the older porcelain made at a later period, but in such a conservative country as China this reservation is of no great importance. We must remember that in all these wares there was no other decoration than that given by the glaze as applied to the variously moulded or incised surface of the paste. The nature of the glaze was therefore of pre-eminent importance. The range of colour, except in the rare flambé vases, was in the main confined to shades of blue and green, and even of these colours pronounced tints are rare. All the colours at the command of the potters of these days were derived from the oxides of iron and copper. And yet with such simple elements, what an infinite variety! It has been truly said by a French writer that the beauty of the glaze is the qualité maîtresse de la céramique, and it is partly a recognition of this claim that has led so many French and American collectors, of late, to follow the example of the Chinese and Japanese connoisseurs, and to give so marked a preference to monochrome porcelains, which owe their charm to the merits of the glaze alone. But the specimens we find in these collections are with but few exceptions of much later date. The price that a fine piece of Sung ware, above all if it has a good pedigree and comes from a known collection, has always commanded in China has sufficed, at least until quite lately, to keep such specimens in their native country.
PLATE IV. CHINESE
As we have said, there are very few examples in our public collections that can with any assurance be attributed to Sung times. In the British Museum, in the same case with the Kien yao tea-bowl already mentioned, is a jar some twelve inches in height, with two small handles on the shoulder. It is of irregular shape and covered with a thick glaze of a pale turquoise blue, faintly crackled. Close to the mouth is a bright red mark, like a piece of sealing-wax, due probably to the local partial reduction of the copper. This beautiful but very archaic-looking jar (Pl. iv.) is attributed to no earlier date than the later or southern Sung dynasty (1127-1279). Among the large number of crackle monochrome pieces in the same collection there are many specimens which a Chinese connoisseur would classify as Ko yao, and similarly some of the old flambé pieces might be termed Chün yao, without definitely assigning them to Sung times. The Lung-Chuan celadons are represented by some early pieces, more than one distinguished by the red foot. There are some fine plates of old heavy celadon at South Kensington, not a few purchased in Persia. Here may also be found a celadon jar cut down at the neck; and the ‘mouth’ thus artificially formed has been carefully stained of a red colour to imitate the old ware. The French museums are particularly rich in specimens of old martabani celadon—I would point especially to several large dishes both at Sèvres and in the Musée Guimet. But what is perhaps the finest collection in Europe of celadon and other old wares is now to be seen in the museum at Gotha. It was brought together by the late Duke of Edinburgh, who added to previous acquisitions the collection formed in China by Dr. Hirth.
Probably at no period during its long history has the Chinese empire been subjected to such a thorough shaking up, to such a complete upsetting and reversal of its ancient ways, as during the advance of the Mongols from the north to the south during the twelfth and thirteenth centuries. When they had at length subdued the whole land, there was a moment during the rule of the liberal-minded Kublai Khan when the old barriers and prejudices seemed to have been broken down, and when the Middle Kingdom appeared to be about to enter the general comity of nations. This is what gives to Marco Polo’s account of the country, which he visited at the time, so very ‘un-Chinese’ an air. We hear of Italian friars and French goldsmiths at the court, and of projected embassies from the Pope. Still closer were the relations with the Mohammedan people of Western Asia, then ruled by members of Kublai’s family. Marco Polo, we know, formed part of the escort of Kublai’s sister, when she travelled by sea to Persia to become the bride of the Mongol khan of that country; and a predecessor of this latter ruler, Hulugu, as early as the middle of the thirteenth century, brought over, it is said, as many as a thousand Chinese artificers and settled them in Persia.
And yet when scarcely two generations later the degenerate descendants of Kublai were driven from the imperial throne and replaced by a native dynasty, what slight permanent trace do we see of all these changes reflected in the arts of the Middle Kingdom! No doubt, on looking closely, we should find that a change had taken place during these years: new materials had been brought in, new forms and new decorations applied to the metal ware and the pottery of the Chinese. It is in connection with these two arts especially (and we may add to them the designs on textile fabrics) that we find so many points of interest in the mutual influence of the civilisations of China and Persia at this time. We must remember that in the thirteenth century the craftsman of Persia, as the inheritor of both Saracenic and older traditions, was in many respects ahead of his rival artist in China.
As far as the potter’s art was concerned this was the first meeting of two contrasted schools, which between them cover pretty well the whole field of ceramics—of that part at least of the field in which the glaze is the principal element in the decoration.35
The Persian ware of this time was the culminating example of an art that had been handed down from the Egyptians and the Assyrians. As a rule, among these races, the baser nature of the paste had been concealed by a more or less opaque coating either of a fine clay or ‘slip,’ or of a glaze rendered non-transparent by the addition of tin; it is on this coating that the decoration is painted, to be covered subsequently (in the first case at least, that of the slip ware) by a coating of glaze. It is to this large class, for the most part to the latter or stanniferous division, that nearly all the famous wares of the European renaissance belong, not only the Spanish and Italian majolica but the enamelled fayence of France and Holland as well. It was with the latter two wares that at a later date the porcelain of China was destined to come into competition. Each of these ceramic schools, the Eastern porcelain and the Western fayence, might in certain points claim advantages over the other, advantages both of a practical and of an æsthetic nature. For example, the glory of the Persian fayence of that day lay in its application to architecture, in the brilliant coating of tiles that covered the walls and the domes of the mosques and dwellings both inside and out. The Chinese have never succeeded in making tiles of any size with their porcelain. When used for the decoration of buildings the porcelain, or rather the earthenware, is always in the form of solid, moulded bricks.
But there is another matter with which the Chinese who visited Western Asia at that time cannot fail to have been struck—with the materials, I mean, at the command of the Persians, for the application of colour both under and over the glaze. Of the decorations over the glaze the most important were those given by their famous metallic lustres. This lustre, we now know, was the result of an ingenious process by which a film of copper, or sometimes of silver, was developed on the surface of the glaze.
The Chinese have never attempted anything of the kind, in part because such a method of adornment was foreign to their notions of what was fitting. For we must bear in mind that the influence of the literary tradition in China has always tended towards simplicity of means in their decorative arts, and has
Somewhat later the Chinese were for a time neighbours of the Sassanian empire, where the arts of glazing pottery and making glass were highly developed. Sassanian bronzes, and probably textiles, have found their way to Japan.
