Porcelain. Dillon Edward

      There are several specimens of blue and white in England, the metal mountings of which date from the early seventeenth or even from the sixteenth century. Of these the most famous are the four pieces from Burleigh House (now belonging to Mr. Pierpont Morgan), which are believed to have been in the possession of the Cecil family from the time of Queen Elizabeth. One of these bears the date-mark of Wan-li, the contemporary of that queen. This ware is not particularly fine, the surfaces are irregular, and all the pieces are apparently moulded (Pl. xxviii.).

      This subject, however, of the early presence of Chinese porcelain in other lands we shall return to in a later chapter.

      So far, then, with such imperfect lights as are at our command, we have attempted to follow up the history of porcelain, and so far, say up to the middle of the sixteenth century, China is practically the only country with which we are concerned. Some fair imitations of celadon, the martabani of Oriental commerce, had probably by this time been made in Siam and perhaps elsewhere, and the Japanese were already in a sporadic way experimenting with imported and native clays. But up to the sixteenth century the Chinese had practically the monopoly of the art, and as we have seen they had at that time the command of three processes of decoration—that is by monochrome glazes, by painting with glazes of a few simple colours on the biscuit, and finally by means of cobalt blues and copper reds painted on the surface of the raw paste.

      Not but that some attempts may have already been made to apply coloured decoration over the glaze—the next and final step in the history of porcelain. There are some passages in contemporary Chinese books, giving descriptions of elaborate subjects painted in many colours on porcelain of the fifteenth and sixteenth centuries, which it would be difficult to apply to our class of painted glazes. Thus—to take a pronounced instance from an unexceptionable source—the miniature wine-cups, No. 59 of the Bushell manuscript, are attributed by Tzu-ching to the reign of Cheng-hua (1464-87), and he describes them thus—‘They are painted in enamel colours’ (so Dr. Bushell translates the original) ‘with flowers and insects; … the cockscomb, the narcissus and other flowers, the flying dragon-fly and crawling mantis are minutely painted after life in green, yellow, and crimson enamel.’ (This, by the way, is a combination of colours which it must have been difficult to apply at one firing with the pigments known at that time.) And yet in the absence of any specimen of enamelled ware (using the word enamel in its restricted sense for a decoration applied over the glaze) that can with certainty be attributed to so early a period, it will be safer to postpone the date of the introduction of this decoration, sur couverte, for another hundred years.

      It will be remembered that the distinctive feature of this decoration with enamels is the use of an easily fusible silicate, containing much lead—in fact a kind of flint glass. A glass of this description is capable of being stained by the addition of small quantities of certain metallic oxides, some of which would not stand the heat requisite for the firing of the porcelain. This, in fact, is the application to porcelain of the arts of the glass-stainer and of the enameller, arts already at this time fully developed in the West. For once the Chinese authorities all agree in finding in an exotic and indeed Western art the origin of their enamelled porcelain. When, however, we attempt to interpret their statements we are landed in an even more than customary chaos—so many are the different readings for the names of foreign countries and for technical processes.

      Let us then consider for a moment what the materials were that the Chinese had to draw from—whether from Arab or other sources.

      Putting aside the application of stained glass to windows, for specimens of this art are not easily exported, these may be summed up as, first, the enamelled glass of the Saracens, and secondly, the cloisonnés and champlevés enamels of the Byzantines and other Western nations.

      As to the first—the application of coloured and easily fusible enamels to the surface of glass, which was then exposed to a second firing—this process had been used by the Arabs for the decoration of their mosque lamps and other vessels probably as early as the twelfth century, and this was an art identical in its system with the application of the same colours to the surface of porcelain. The beauty of the effect cannot have failed to have struck the Chinese if they had had any opportunity of seeing the finer specimens. But the material was fragile, and apart from a statement by M. Scherer that glass was exported from Aleppo to China,44 I cannot find in the accounts of the Arab trade of the time any record of such ware being imported into China.

      On the other hand, we know that enamels on metal are first mentioned in the Ming annals about the middle of the fifteenth century. They take their name of Cheng-tai enamels from the emperor who reigned at that period; but the proper Chinese term for such enamels is Folang chien yao—‘the inlaid ware of Folang.’ Julien interpreted these words ‘Porcelaines à incrustations (ornées d’émaux) de France,’ and Dr. Hirth carries us to Bethlehem! But the word Folang is probably the same as the term Folin or Fulen, used as early as the sixth century for the Roman empire of the East, and it may possibly be connected with the Greek πόλις (cf. Stamboul = Εἰς τὴν πόλιν).45 It is definitely stated by a later Chinese writer that the same colours are employed by both the enameller on metal and the decorator of porcelain.

      If we examine the colours found on both the wares to which we have tentatively traced back the enamelled porcelain of the Chinese—the enamels on glass on the one hand, and those on metal on the other—taking in each case the earlier specimens as examples, we find on the mosque lamps from Cairo little except a deep blue generally used as a ground for a design which is outlined in an opaque iron red. On the famous flask from Würzburg, now in the British Museum, for which a ‘Mesopotamian’ origin of the thirteenth century is claimed, a turquoise blue relieved by gilding is the predominant note; there is also a sparing use of yellow, of an opaque white, and, what is especially interesting, of a fine pinkish red, which is possibly obtained from gold. (The way in which this colour is shaded into the opaque white reminds us of the similar use of the rouge d’or in later times in China.)

      If, on the other hand, we turn to the earlier Chinese enamels on metal, the so-called Ching-tai vases, attributed to the fifteenth century, we find among the colours used an opaque iron red, a yellow, an opaque white, and finally two kinds of blue, a turquoise and a full deep blue that looks like a cobalt colour.46

      Some time, then, during the sixteenth century, whether before or after the accession of Wan-li (1572), the Chinese began to decorate the surface of their porcelain with jewel-like enamels appliqués to the glaze. At first, apparently, these colours were confined to three: a copper green, a yellow generally of a buff tint, probably containing antimony as well as iron, and a purple derived from manganese. These are the San-tsai or three colours of the Chinese writers, and it will be seen that they differ from the colour triad of our ‘painted glazes’ (painted, that is, on biscuit and reheated in the demi grand feu) in that the copper silicate is of a turquoise blue in the latter, and in the former of a full leafy green. The Chinese authorities further tell us that a second scheme of decoration was given by the Wu-tsai or the five colours which were made up by the three already mentioned, with the addition of an opaque red derived from the sesqui-oxide of iron (otherwise known as hæmatite, bole or red ochre),47 and finally of a cobalt blue, sous couverte, surviving as it were from the earlier blue and white ware, for, as we have mentioned, the use of the blue as an enamel over the glaze belongs to a later
