It would be impossible to over–estimate the importance of Bushell's pioneer work; and I hasten to make the fullest acknowledgment of the free use I have made of his writings, the more so because I have not hesitated to criticise freely his translations where necessary. The Chinese language is notoriously obscure and ambiguous, and differences of opinion on difficult passages are inevitable. In fact, I would say that it is unwise to build up theories on any translation whatsoever without verifying the critical passages in the original. For this reason I found it necessary to work laboriously through the available Chinese ceramic literature, a task which would have been quite impossible with my brief acquaintance with the language had it not been for the invaluable aid of Dr. Lionel Giles, who helped me over the difficult ground. I have, moreover, taken the precaution of giving the Chinese text in all critical passages, so that the reader may satisfy himself as to their true meaning.
While Dr. Bushell's contributions have greatly simplified the study of the later Chinese porcelains, little or no account was taken in the older books of the pottery and early wares. The materials necessary for the study of these were wanting in Europe. Stray examples of the coarser types and export wares had found their way into our collections, but not in sufficient numbers or importance to arouse any general interest, and the condition of the Western market for the early types was not such as to tempt the native collector to part with his rare and valued specimens. In the last few years the position has completely changed. The opening up of China and the increased opportunities which Europeans enjoy, not only for studying the monuments of ancient Chinese art, but for acquiring examples of the early masterpieces in painting, sculpture, bronze, jade, and ceramic wares, have given the Western student a truer insight into the greatness of the earlier phases of Chinese art, and have awakened a new and widespread enthusiasm for them. An immense quantity of objects, interesting both artistically and archæologically, has been discovered in the tombs which railway construction has incidentally opened; and although this rich material has been gathered haphazard and under the least favourable conditions for accurate classification, a great deal has been learnt, and it is not too much to say that the study of early Chinese art has been completely revolutionised. Numerous collections have been formed, and the resulting competition has created a market into which even the treasured specimens of the Chinese collectors are being lured. Political circumstances have been another factor of the situation, and the Western collector has profited by the unhappy conditions which have prevailed in China since the revolution in 1912.
The result of all this, ceramically speaking, is that we are now familiar with the pottery of the Han dynasty; the ceramic art of the T´ang period has been unfolded in wholly unexpected splendour; the Sung problems no longer consist in reconciling ambiguous Chinese phrases, but in the classification of actual specimens; the Ming porcelain is seen in clearer perspective, and our already considerable information on the wares of the last dynasty has been revised and supplemented by further studies. So much progress, in fact, has been made, that it was high time to take stock of the present position, and to set out the material which has been collected, not, of course, with any thoughts of finality, but to serve as a basis for a further forward move. That is the purpose of the present volumes, in which I have attempted merely to lay before the reader the existing material for studying Chinese ceramics as I have found it, adding my own conclusions and comments, which he may or may not accept.
The most striking additions to our knowledge in recent years, have without doubt been those which concern the T´ang pottery. What was previously a blank is now filled with a rich series covering the whole gamut of ceramic wares, from a soft plaster–like material through faïence and stoneware up to true porcelain. The T´ang potters had little to learn in technical matters. They used the soft lead glazes, coloured green, blue, amber, and purplish brown by the same metallic oxides as formed the basis of the cognate glazes on Ming pottery. They used high–fired feldspathic glazes, white, brownish green, chocolate brown, purplish black, and tea–dust green, sometimes with frothy splashes of grey or bluish grey, as on the Sung wares. Sometimes these glazes were superposed as on the Japanese tea jars, which avowedly owed their technique to Chinese models. It is evident that streaked and mottled effects appealed specially to the taste of the time, and marbling both of the glaze and of the body was practised. Carving designs in low relief, or incising them with a pointed instrument and filling in the spaces with coloured glazes, stamping small patterns on the body, and applying reliefs which had been previously pressed out in moulds, were methods employed for surface decoration. Painted designs in unfired pigments appear on some of the tomb wares, and it is now practically certain that painting in black under a green glaze was used by the T´ang potters. Moreover, the existence of porcelain proper in the T´ang period is definitely established.
One of the most remarkable features of T´ang pottery is the strong Hellenistic flavour apparent in the shapes of the vessels and in certain details of the ornament, particularly in the former. Other foreign influences observable in T´ang art are Persian, Sassanian, Scytho–Siberian, and Indian, and one would say that Chinese art at this period was in a peculiarly receptive state. As compared with the conventional style of later ages which we have come to regard as characteristically Chinese, the T´ang art is quite distinctive, and almost foreign in many of its aspects.
The revelation of T´ang ceramics has provided many surprises, and doubtless there are more in store for us. There are certainly many gaps to fill and many apparent anomalies to explain. We are still in the dark with regard to the potter's art of the four hundred years which separate the Han and T´ang dynasties. The Buddhist sculptures of this time reveal a high level of artistic development, and we may assume that the minor arts, and pottery among them, were not neglected. When some light is shed from excavation or otherwise upon this obscure interval, no doubt we shall see that we have fixed our boundaries too rigidly, and that the Han types must be carried forward and the T´ang types carried back to bridge the gap. Meanwhile, we can only make the best of the facts which have been revealed at present, keeping our classification as elastic as possible. Probably the soft lead glazes belong to the earlier part of the T´ang period and extend back to the Sui and Wei, linking up with the green glaze of the Han pottery, while the high–fired glazes tended to supersede these in the latter part of the dynasty.
The high–fired feldspathic glazes seem to have held the field entirely in the Sung dynasty, and the lead glazes, as far as our observation goes, do not reappear until the Ming dynasty.
The Sung is the age of high–fired glazes, splendid in their lavish richness and in the subtle and often unforeseen tints which emerge from their opalescent depths. It is also an age of bold, free potting, robust and virile forms, an age of pottery in its purest manifestation. Painted ornament was used at certain factories in black and coloured clays, and, it would seem, even in red and green enamels; but painted ornament was less esteemed than the true ceramic decoration obtained by carving, incising, and moulding—processes which the potters worked with the clay alone.
If we could rest content with a comprehensive classification of the Sung wares, as we have had perforce to do in the case of the T´ang, one of the chief difficulties in this part of our task would be avoided. But the Chinese have given us a number of important headings, under which it has become obligatory to try and group our specimens. Some of these types have been clearly identified, but there are others which still remain vague and ill–defined; and there are many specimens, especially among the coarser kinds of ware, which cannot be referred to any of the main groups. But the true collector will not find the difficulties connected with the Sung wares in any way discouraging. He will revel in them, taking pleasure in the fact that he has new ground to break, many riddles to solve, and a subject to master which is worthy of his steel.
Apparently a coarse form of painting in blue was employed at one factory at least in the Sung period,[3] and we may now consider it practically certain that the first essays in painting both under and over the glaze go back several centuries earlier than was previously supposed. Blue and white and polychrome porcelain chiefly occupied the energies of the Imperial potters at Ching–tê Chên in the Ming dynasty, and the classic periods for these types fall in the fifteenth century. The vogue of the Sung glazes scarcely survived the brief intermediate dynasty of the Yüan, and we are told by a Chinese writer[4] that "on the advent of the Ming dynasty the pi sê[5] began to disappear." Pictorial ornament and painted brocade patterns were in favour on the Ming wares; and it will be observed that as compared with those of the later porcelains the Ming designs are painted with more freedom and individuality. In the Ch´ing dynasty the appetite of the Ching–tê Chên potters was omnivorous and their skill was supreme. They are not only noted for certain specialities, such as the K´ang Hsi blue and white and famille verte, the sang de bœuf and peach–bloom reds, and for the development of the famille rose palette, but for the revival of all the celebrated types of the classic periods of the Sung and Ming; and when they had exhausted the possibilities of these they turned to other materials and copied with magical exactitude the ornaments in metal, carved stone, lacquer, wood, shell, glass—in a word, every artistic substance, whether natural or artificial.
