The Potter’s Wheel Index 79 86 92 95 no 120 148 178 The Beginnings of Porcelain in China INTRODUCTORY In February of 1910, while in Si-ngan fu, the capital of Shen-si Province, the writer received from Mr. Yen, a Chinese scholar and antiquarian of note with whom he was on very friendly terms, a curious bit of ancient pottery, which at first sight bore all the characteristic marks associated with what is known as Han pottery, but which, on the other hand, exhibited a body and a glaze radically different from that ware (Plate I). Mr. Yen accompanied the object with a written message, explaining the circumstances under which it had been found, and commenting to some extent on its historical value. Following is a literal rendering of his letter: “I once heard dealers say that they had seen ‘Han porcelain’ {Han ts'e but I had no faith in this statement. In the winter of the year ting wei T (1907) I secured a large vase, and suspected that it might be an object of the Han period, but did not dare to be positive about this point. In the spring of last year some one brought to light, from a Han grave which he had excavated, ancient jade pieces and such-like things, together with an enormous iron cooking-stove. On the latter are found, cast in high relief, six characters reading, ‘Great felicity! May it be service- able to the lords! ’ {ta ki ch'ang i hou wang 'a ^ i ). On the top of this stove was placed a small ‘porcelain jar.’ I lost no time in sending out an agent to effect a purchase, but the stove had already passed into the hands of a merchant. So I obtained only the ‘porce- lain jar’ in question, the material and style of which proved identical with those of the large vase purchased by me years ago. For this reason I now felt positive that the question is here of ‘Han porcelain.’ Subsequently I acquired also a jar of the type styled lei and big and small vases; in all, four. From that time the designation ‘Han porcelain’ began to be established in the world. “Written in Ch'ang-ngan by Yen Kan-ytian ^ @ on the day when the flowers sprout forth (W tE ^ 0), of the second month of the second year of the period Siian-t'ung (February 27, 1910).” While I had a deep respect for Mr. Yen’s learning and extensive knowledge of archaeological subjects, I remained sceptic as to the identification of his jar with what he styled Han ts'e, and, though recog- nizing its intrinsic merit as a piece of evidence filling a lacune in oirr 79 8o Beginnings oe Porcelain knowledge of ancient pottery, I did not allow myself to be carried away by the usual wave of enthusiasm over a first discovery (since then six years and a half have elapsed), but decided to hold the matter in abeyance till a thorough analysis, to be made at home, would permit us to base an opinion on facts. Meanwhile opportunities were seized at Si-ngan fu to collect as much as possible of this novel pottery. My first concern, naturally, was to secure the large iron stove mentioned in Mr. Yen’s missive. A desire thus expressed spreads in that quaint old town like a prairie-fire; and when the sun had risen and set again, I was the lucky owner of that precious relic. Indeed, Yen’s descrip- tion was by no means an exaggeration. In type and style, this cast- iron stove (Plate II), partly in decay and the iron core having entirely rotted away, exactly corresponds to the well-known Han burial cooking- stoves, and it is the finest specimen of ancient cast-iron that I was able to find. Being posed on four feet in the form of elephant-heads, it is built in the shape of a horse-shoe, and provided with a chimney at the rounded end, five cooking-holes, and a projecting platform in front of the fire-chamber. On the latter is cast an inscription in six raised characters, which read exactly as indicated by Mr. Yen, — a formula typical of the Han and earlier ages, and encountered on many bronze vessels. The style of these characters is in thorough agreement with that of Han writing. The object was discovered in a grave near the village Ma-kia-chai ^ ^ M, 5 li north of the town Hien-yang, in Shen-si Province. As previously remarked,^ without laying down any hard and fast rules, there is a great deal of probability in assigning such cast-iron objects to the period of the Later Han (a.d. 25-220), while it is equally justifiable to extend the time of their manufac- ture over the entire third century of our era. The iron stove thus furnishes a clew to the date of the jug which was found in the same grave with it. Needless to say, I left no stone unturned, and kept on inquiring and hunting for this so-called Han ts'e ware in and around Si-ngan. I succeeded in bringing together only eight more pieces (Plates HI-X), among these the vessel lei referred to in Yen’s memorable epistle,^ and a number of larger fragments and small shards, which are always precious and encouraging acquisitions to the archaeologist, as they are not under suspicion, and offer welcome study material. * Chinese Clay Figures, p. 216. * The pottery vase of this designation is mentioned in the Chou li as holding the sacrificial spirits called ch'ang, which were offered to the deity Earth (Biot, Tcheou-li, Vol. I, p. 468). It is the reproduction in clay of an original bronze- type, frequent among the bronze vessels of the Chou. Introductory 8i It will be noticed that these nine bits, in their forms and decorations, decidedly agree with the mortuary Han pottery,^ and that, taken merely as ceramic types, they represent archaic types of Han art. On the other hand, however, apart from their technical composition, they have in common some characteristic features which are not found in Han pottery. To these belong the curious loop handles, obviously imitative of a knotted rope or a basketry handle, and the geometric wave patterns. The latter, it will be remembered, occur also in the relief bands on many vases of Han pottery, but are of a different style, in the manner of realistic waves. There is in our col- lection only one unglazed, gray Han pottery vase with a geometric wave design approaching that in the above group; but it is a much bolder and freer composition, and not so neat and refined as in the porcelanous vases. Even in some shapes, the traditional rules of the Han may not be quite strictly observed; they may be less stern rigorous, and, while dignified and partially imposing, treated with somewhat greater individual freedom. This, however, is rather a point of sentiment or impression than a ponderable argument. The deviations from the standard Han pottery are insignificant when con- trasted v/ith what the two groups have in common. The best tradition and spirit of Han art are preserved in these nine productions. The comparative scarcity of this ware is notable, and gives food for serious reflection. As the writer was able to secure on his last expedition for the Field Museum many hundreds of pieces of Han pot- tery of all types and descriptions, while several thousand specimens have passed through his hands during the last fifteen years, and as he could hunt up only nine representatives of this novel (porcelanous) ware, these numbers may be regarded as the relative (certainly not absolute; proportions in which the two classes of pottery are to be found, and, we may add, were made in the past. Two inferences may be drawn from this phenomenon, — this peculiar ware was the product of only a single kiln or of very few kilns; and these kilns did not flourish during the Han period, but either at its very close, or even, and more probably, toward the middle or end of the third century. This point will be more fully discussed hereafter. ^ In speaking of Han pottery, it should be understood that in this case the term “Han” does not refer to the chronologically exact boundaries of a dynastic period, but to an archceological epoch, a certain phase of ancient Chinese art, which is not necessarily gauged by the dates 206 B.c. and a.d. 220. There is naturally an overlapping at both ends, and we have, at least for the present, no means of determining exactly either the beginning or the end of Han art. This much seems certain, that the middle and the latter part of the third century a.d. have thor- oughly remained under the influence of Han tradition. 82 Beginnings of Porcelain On my return to America, two objects remained to be pursued in connection with this new material, — first, to secure the co-operation of a competent investigator for a chemical analysis of the body and glaze of this pottery; and, second, to search in other museums for corresponding specimens. My colleague Mr. Nichols, assistant curator of geology in the Field Museum, volunteered to undertake the technical task, and he has carried it out with rare devotion and perseverance. His experiments were conducted, and his results were obtained, in 1912. From the date of our publication it will be seen that we were not in a hurry to bring it to the notice of the world. We allowed it to rest and to mature, and discussed the new problems with each other and with ceramic experts at frequent intervals. Their friendly interest and advice at last encouraged us to make known the results of our research, which we trust will be of some utility to students interested A.^ithe history of Chinese pottery. In regard to kindred objects in other collections, I have been able to obtain the following information. Mr. Francis Stewart Kershaw of the Museum of Fine Arts, Boston, Mass., who saw the pieces of pottery in question in the Field Museum, mentioned to me that similar specimens were in the Boston Museum. On sending him some frag- ments from our material for comparison with that under his care, he wrote as follows:^ “The bits of potsherd are quite large enough to tell me their story, and I am very much obliged for them. Except in hardness, they are similar to the clay of three of our pieces, being of the same color, texture, and apparent constituents. Two of our pieces were bought in China by Mr. Okakura, and both were labelled ‘Sung’ by some Chinese (probably a dealer). Okakura called one (12875) which is covered with a blackish shaded gray-green glaze, opaque and dull, ‘Sung.’ The second (12865), which is precisely similar in potting, clay, and glaze, to your Han porcelanous jars, Okakura called ‘T'ang.’ Mr. Freer, by the way, has a vase like 12865, which he calls ‘T'ang.’^ The third of our pieces (12118) was bought from Mr. C. F. Gammon (for- merly a lieutenant in the United States Army), who obtained it in Nanking from a cooly, who had unearthed it while digging in a railway cutting in Nanking. The jar was partly full of coins, all alike, of the denomination ^pan Hang' M, issued in 175 b.c. in the reign of the 1 The letter is published here with Mr. Kershaw’s consent. ^ This object was exhibited in the National Museum of Washington in 1912, when a selection from the Freer Collection was temporarily shown. I then had occasion to see it. It is not a T'ang production, but of exactly the same type as our early porcelanous ware. Introductory 83 Emperor Wen. Mr. Gammon told me that he had bought the jar on the spot where it was found. The jar itself, like the others belong- ing to us, was welded or coiled up by hand before a summary smooth- ing-off on the wheel. It had four loop handles, finger-modelled, at the shoulder (two only of these remain), and was glazed in a thin running blackish-green, of which the little that still adheres is for the most part oxidized to dull brownish-ochre. The clay is softer than your shards, and softer, too, than that of 12865 or 12875; but it seems to be quite the same in all other respects. It has the same admixture of black and occasional white particles in the mass of gray, the same unevenly ferruginous surface, and the same occasional thickening of that surface. The jar is much less well potted than your pieces and ours. Perhaps it is more primitive; that is, it may be an early example of the method used so expertly in making your jars and ours. Perhaps, on the other hand, it is simply cruder; that is, the potter may have used a well-known and well-developed method carelessly in making an unimportant vessel. Who knows? I incline toward the latter possibility. “I dated the jar ‘Han’ because of the evidence of the coins found in it. Now, emboldened by your ascription of the date to the porce- lanous jars, I shall classify No. 12865 the Han period or shortly after. As regards 12875, because of its different glaze and an obscure device impressed on its shoiolder, I am not yet sure.” At my request Mr. Kershaw was good enough to send me for ex- amination the pan-liang copper coins, twenty-one all together, found in Mr. Gammon’s jar. They all proved to be authentic, as particularly determined by close comparison with numerous corresponding issues in the Chalfant coin collection, and to have been issued under the Han.^ The presence of this batch of coins in that vessel is, of comse, no abso- lute proof warranting us in assigning the vessel to the early Han period, as these coins may still have been in circulation long after Plan times. In 1901 I found in actual circulation at Si-ngan fu Han copper coins with the legend wu chu. A collection of twenty-one Han pan-liang coins in a single jar would rather hint at a high appreciation of this money, and such is rather more probable in post-Han than in Han times. At any rate, the exclusive presence of a single Han issue, together with the absence of any later coin, would seem to favor a period approaching very closely the age of the Han. 1 Money with this legend, weighing exactly half an ounce {pan-liang), was first issued under the Ts'in (see Chavannes, Memoires historiques de Se-ma Ts'ien, Vol. Ill, pp. 539, 542). 84 Beginnings oe Porcelain Several similar pieces have been collected by Mr. Orvar Karlbeck, an official of the Tientsin-Pukow Railway, residing at Chu-chou, Ngan-hui Province. This gentleman, in the course of several years’ residence in China, has formed a very interesting collection of ancient pottery, that consists of 144 pieces. I did not have occasion to see it, but, judging from photographs and descriptions which he has been good enough to send me, he seems to own several bits such as are here under consideration. Mr. R. L. Hobson, the prominent expert in pottery of the British Museum, while visiting Chicago in January, 1913, and doing me the honor of studying the collections under my care, called my attention to two early jars of similar glazes which were found at Black Rock Hill in Fu-chou, and are now preserved in the British Museum. They are sketched and described by H. F. Holt.^ They are oval-shaped jars, with short necks and straight rims, a pair of loop handles (in one piece double handles) being stuck on to the shoulders. They are described as being made “of a grayish clay resembling almost stone- ware, over which a coat of greenish-brown glaze has been coarsely laid; a curved line at the bottom sharply defines where the glazing ended.” The further remark, however, that the glaze is quite decomposed and can easily be detached, would rather hint at this glaze being of a char- acter different from that on our specimens, which, owing to its chemical composition, is not capable of decomposition. The great antiquity of these two jars is not doubtful: in shape and style they are true descendants of Han pottery. Holt adduces an interesting piece of evidence as to their age, — the fact that the grave in which they were found was situated within the city- walls; and, as no burial within the latter is permitted, they would seem to have been deposited there at a time prior to the erection of the wall. He refers to the “Geography of the Manchu Dynasty” {Ta Ts'ing i t'ung chi) as containing the information that in a.d. 625 Fu-chou was a city of the first class. Mr. Hobson was also good enough to read in manuscript Mr. Nichols’s report, that follows, and to anticipate some of these results in his admirable work “Chinese Pottery and Porcelain,”^ which denotes decided progress in our knowledge of the entire subject, and is now the best general handbook on porcelain. Referring to Mr. Nichols’s analyses of the body and glaze of this pottery, Mr. Hobson states, “The results show that the body is composed of a kaolin-like material ^ On Chinese Cinerary Urns {Journal British Archaological Association, Vol. XXVII, 1871, pp. 343-349, Plate XVII). ^ Vol. I, p. 15 (New York and London, 1915). Introductory 85 (probably a kind of decomposed pegmatite), and is, in fact, an incipient porcelain, lacking a sufficient grinding of the material. The glaze is composed of the same material softened with powdered limestone and colored with iron oxide. . . . The nature of the pottery, in spite of its coarse grain and dark color, which is probably due in part to the presence of iron in the clay, seems to show that the manufacture of porcelain was not far distant.” The report of Mr. Nichols is of sufficient importance and interest to warrant its publication in full. It is divided into two parts. Part I is devoted to a detailed investigation of the ancient porcelanous ware; and, in order to render possible a comparison with the earlier Han pottery, analysis of a green glaze from a bowl of Han pottery follows in Part II. REPORT ON A TECHNICAL INVESTIGATION OF ANCIENT CHINESE POTTERY By H. W. Nichols I. PORCELANOUS HaN PoTTERY For the purpose of analysis, one fragment about two inches long and two inches wide, and a number of smaller pieces, were examined. The body of the ware, which is from three-sixteenths to one-quarter of an inch thick, consists of a gray vitrified porous substance which contains a few scattered black specks of minute size and glassy lustre. The body is coated on the outside with a very thin opaque red slip, and on the inside with a white engobe and a thick transparent greenish-yellow glaze.
