I. TECHNICAL PROCESSES IN THE MAKING OF MODERN POTTERY AND THEIR APPLICATION TO THE TECHNIQUE OF ANCIENT VASES
PREPARATION OF THE CLAYIngredients and properties.The making of a pot begins in the clay bed. The clay has to be found, it has to be transported, and above all it has to be tested to see whether it is adapted to the potter’s needs. For there are many different kinds of clay and they are as individual as human beings; so that a thorough understanding of them is essential to the successful potter. The chief ingredients of clay are silica, alumina, and water. Other possible ingredients are iron oxide, lime (calcium oxide), magnesia, and potash. To the iron compounds are due the different colors of the clay. When potters speak of the color of a clay—red, yellow, white—they refer to the color after burning, not in the raw state. The tones of the color are controlled by heat; for instance, a red clay becomes first pink, then in a higher fire a deeper red, and in a still higher fire a brownish red. The potter demands three properties of his clay: (1) plasticity, the property which enables the clay to acquire form; (2) porosity, the property which enables the water to escape; and (3) vitrification, the property which enables the clay to be fired. These three properties are due to the three chief component parts of the clay; namely, clay base, quartz, and feldspar. It will be found that some clays are not plastic enough, others not sufficiently porous, and others again not properly vitrifiable; in such cases the addition of certain substances is necessary to make the clay usable. Washing.When the right composition of the clay has been assured, the next step is to wash it and separate it from the many natural impurities, such as stones, sticks, etc., with which it is mixed. A clay not properly washed is a source of great vexation in the later stages of pottery making. The best method is that of “blunging,” that is, the dry clay is put into water and stirred constantly until it reaches the consistency of cream, technically called “slip,” whereupon it is poured through sieves, coarse or fine according to the desired consistency. The liquid clay or slip must then be dried sufficiently to become plastic and workable. This can be done either in filter presses in which the water is squeezed out in a comparatively short time, or in shallow receptacles in the open air where the water is allowed slowly to evaporate. Wedging.But even at this stage the clay is not yet ready for use; it has first to go through the important process of kneading or “wedging.” This consists of cutting a ball of clay in two against a wire (fig. 1), slapping the two parts on a plaster or wooden board, one on top of the other (fig. 2), then lifting up the whole lump, cutting it in two again, and slapping it down as before. The purpose is to remove all air bubbles and to correct irregularities in hardness. The operation has sometimes to be repeated fifteen or twenty times before a good texture is secured.[5] We learn from the above survey that the fine consistency of the clay in Athenian and in some other Greek wares is not necessarily due to its natural state, but to the careful washing and kneading undergone in its preparation for use. When different particles are found in the fired clay they are due to indifferent washing. And the varying shades of pink and red of Greek vases likewise do not presuppose different kinds of clay, but are due largely to the various temperatures to which the vases were fired. We have too often made our analyses of clays of Greek vases without due cognizance of these facts. FASHIONING THE VASES(1) WHEELWORKThere are three principal ways of making vases—fashioning them on the wheel, building them, and making them from moulds. Let us examine first the work on the wheel, the potter’s tool par excellence. Types of wheel.There are various types of wheel in general use today. The wheel run by electric power does not concern us here since it cannot have been used by the Greeks. In studio Any one of these three types may have been used by the Greeks. In the representations of ancient potters at work (cf. pp. 64 ff.) the wheel appears to have been propelled either with the foot or by an assistant. Throwing.The first task in fashioning a vase on the wheel—or “throwing” it, as it is technically called—is to center the ball of clay on the wheel-head. It is accomplished by pressing the left hand against the ball of clay as it revolves rapidly, care being taken to keep the left forearm absolutely The earliest Greek vases are made by hand; but from the Early Minoan III and Middle Helladic I periods (i.e., about 2200 B.C.) in certain places at least, vases were regularly thrown on the wheel. They could not have the regular and symmetrical outlines they have if they were built by hand, and many would show traces of vertical joints if they were made in moulds. That the processes of throwing were identical with those described as in use today, there is of course no means of determining; but they certainly must have been similar, as clay has not changed its nature from Greek times to ours. The evidence which we glean from representations on Greek vases of potters at work, scanty though it is, bears out this self-evident fact. From the above description it will be noted that in this work of throwing the simultaneous use of both hands is necessary—an important fact to remember when interpreting scenes to be related to the fashioning of vases. Turning.After a piece has been thrown on the wheel, it has assumed its general shape, but that is all. The thinning of the walls, the refinements of foot and lip, all such finishing touches must be reserved for the next process. This is known among modern potters as “turning.” In this the clay is no longer in a wet state, but in a “leather-hard” condition, and it is not worked with the hands but with steel cutting tools. A newly shaped vase becomes leather hard after it has been kept in the air and the water allowed to evaporate for about twenty-four hours. Pieces in this state are hard enough to be handled with care and to be cut easily with a knife. They are not so fragile as either in the This turning or refining of the shape after throwing, was, The fact that the Athenian potter made use of the turning process shows incidentally that he was able to make his vases to very exact measurements. This is important in connection with Jay Hambidge’s theory that Athenian pottery was carefully designed on certain geometrical principles;[9] for if the Athenian potter had confined himself Work in sections.So far we have spoken only of comparatively small vases, which can be thrown all in one piece. Larger vases are best thrown in sections. To throw large jars in one piece requires great physical strength, and it is very difficult to finish such jars properly on the inside and to prevent them from being unduly heavy. The section work is by no means To obtain good results in this work it is important that it should not be hurried. It is best, for instance, before joining the sections, to let them stand on top of one another for a day or longer, in order that they may mature together. To retain the pieces during this time in leather-hard condition, they must be kept in a “wet cellar,” that is, in a moist Section work was used by the Greeks, as it is now. There would, in fact, be nothing gained in throwing the very large vases, such as some of the kraters and amphorai, all in one piece; and though the joints are, as a rule, skilfully concealed, they are plainly visible on certain examples, especially on the inside. Where possible the joints seem to have been made at the natural angles or “articulations” of the vase (that is, at the neck, the foot, etc.); and further to simplify the work, a thin ridge of clay was often added to conceal the joint.[10] One of the most difficult things to throw successfully is a flat, wide bowl on a foot; and the larger the diameter of the bowl the more difficult the task, since the overhanging rim almost always sags at the critical moment. The fifth-century Polishing.To impart a polish, the blade of a knife is applied to the surface while the vase is revolving; for an inward curve a curved tool must be used. The operation is simple and can be accomplished in a few minutes. It is not often employed, however, by the modern potter, whose object is to keep the pores of his vase open for the better adhesion of the glaze with which he intends to cover the surface of his pot. The Athenian potter, on the other hand, put great stress on giving the surface of his vase a fine polish; probably using the simple method described above. The difference between a polished and an unpolished surface is clearly seen on some vases on which the potter has omitted to repolish the parts round the handles where the slip used for the attachment had spilled over (fig. 26). Attachment of handles.The final process in the fashioning of a vase is the attachment of the handles. These can be made either in moulds or by hand. Any one who thinks that the making of handles is a simple or quick process will soon be undeceived. Whether working in plaster, as one would if the handle is made in a mould, or in clay, if it is made by hand, the potter must bestow infinite care on the work, as both clay and plaster are very liable to break; and working on so small a thing as a handle is extremely fussy. The writer personally found nothing so difficult in her whole pottery training as the making of handles. The best method of procedure in handwork is first to shape the handle roughly The handles of Athenian vases show perhaps better than anything else the great skill and sense of beauty of the Athenian potter; and they will repay detailed study (cf. figs. 28-33). They are never, as so often on modern vases, detached pieces stuck on the vase as a kind of afterthought. Rather, they seem to grow out of the vase like branches from a tree, which gives them a wonderful, living quality. Moreover, the place where they were attached, the size, and the curve have been carefully considered both from a practical and from an aesthetic point of view. Athenian handles are made by hand, not in moulds. Practically every pair of handles shows perceptible variations such as are unavoidable in handwork and distinguish it from the mechanical products of moulding. The handles It may be noted that the handles of Athenian vases are not finished off neatly in parts where they were not seen. For instance, the under parts of handles on column kraters are generally left quite rough (fig. 34). This fact, together with that already observed, that the insides of amphorai and hydriai are usually unturned, shows that the Greeks, at least, had no such theories as those often held today that a work should be finished perfectly all over, even in places not ordinarily seen, and were quite willing to save trouble when possible. Many potters today bestow as much care on the inside of a narrow flask as on that of an open bowl. It is characteristic of the sense of proportion of the Greeks that their potters took infinite trouble with what was important—the (2) BUILDINGCompared to the wheelwork the building appears simple at first, but experience will soon show that it too needs considerable practice. Though the actual process has not the glamor and thrill associated with wheelwork, there is a certain quality in a built vase which gives it a value of its own. Building is generally done nowadays by means of coils of clay (fig. 35), which must be a little thicker than the walls of the vase are to be and should be as uniform as possible. To make the foot of the vase, the end of one of these coils is laid in the center of a plaster bat and the rest coiled round in spiral line. To hide the joints the surface is rubbed over with the fingers on both sides. In making the walls of the vase a coil is used for each round and the superfluous clay pinched off, every new coil being begun at a new point. The whole surface, inside and outside, is With this process in mind it is easy to distinguish between built and wheel-made pottery among the Greek wares. In the built pottery, however careful the work, there is always a certain unevenness of outline—which indeed gives it some of its charm. Unlike the moderns, the Greeks did not continue to build pottery after the invention of the wheel. Naturally the general adoption of the wheel was not synchronous in all ceramic centers. It was used considerably earlier in Crete, for instance, than in Cyprus. But when once its convenience was thoroughly realized, the slower and more monotonous method was entirely dropped. Among Athenian black-figured and red-figured vases there are no built pieces. (3) MOULDINGThe process of moulding vases is the one most in use nowadays, for the simple reason that when once the required mould has been made the production of any number of vases is a rapid and easy task. But though commercially favored, this method is looked down upon by the artistic potter as being purely mechanical, and there is no doubt that a moulded vase has all the characteristics of machine work. The material used for moulds nowadays is plaster. The clay can either be poured into a mould in slip form or pressed into a mould while soft and plastic. In the former process the mould or moulds are made in two or more pieces, which fit closely together leaving an opening at the top. In pressing clay into moulds each part of the mould is used separately, except where only one mould is required, as in the case of an open bowl or tile. When the clay has been carefully pressed into every part of the mould, it is left to harden, and then, upon shrinkage, can be easily separated. If the vase has been pressed in several pieces, the parts must be carefully joined and the seams effaced as neatly as possible. The Greek potter did not use moulding as a labor-saving device. He employed it only where the work demanded it, The material of Greek moulds was burnt clay. That the Athenian plastic vases were pressed into moulds rather than poured can be seen from the fact that the insides of these vases are rough and show finger-marks (cf. fig. 37). The joints of the two parts are clearly visible on many examples (cf. fig. 38). Often the lip was thrown separately on the wheel and attached. FIRING THE VASESProduction of Temperature.In the fire the great miracle takes place and the dry clay, most friable and perishable of materials, becomes one of the most durable. This is accomplished by the softening of the We shall see presently how important is a knowledge of these chemical changes during the process of firing when we come to consider the defects on Greek vases caused by injuries in the firing (cf. pp. 44 ff.). Types of kilns.There are two chief types of kiln construction in use today: (1) the open kiln, in which the flame passes through the kiln chamber (fig. 39); (2) the muffle kiln, in which the flame passes around the chamber and not through it (fig. 40). In the open kiln the ware either comes in direct contact with the flame, or is stacked in saggers, i.e., boxes made of fire clay fitting one on top of the other (fig. 41). The muffle kiln is, so to speak, one large sagger, and the ware is Packing the kiln.In packing the kiln the ware is stacked as closely as possible for economical reasons, so that as much as possible shall be accomplished in one firing. In biscuit firing the ware can be placed so that it touches (fig. 40); in glaze firing the pieces must be separated (fig. 42) both from one another and from the bottom of the saggers or shelves on which they stand, since the melted glaze is apt to run. Glazed pieces are therefore generally placed on stilts made of burnt clay, and the marks of these stilts will often show on the bottoms of the vases. That the chief features of modern and Athenian kilns were similar is clear from an examination of the ancient representations of kilns (cf. figs. 72-81 and pp. 76 ff.). How closely the ware was sometimes stacked is clearly seen in fig. 80. The fuel used by the Greeks was probably wood and charcoal. Almost all modern pottery is twice fired; once for the conversion of the clay into terracotta or biscuit, and the second time for the glaze. To glaze unbiscuited ware is a delicate business, and the risk of glazing a piece of raw clay is considered larger than the trouble of burning it a second time. It is done occasionally when very tough clay is used, for instance, in kitchen crooks and in stoneware; in that case it is best to apply the glaze when the clay is in leather-hard condition, for then the absorption is less. More than the two regular firings are often used for correcting mistakes in glazing, for additional coats of glaze, and for decorating the ware. Firing.Different wares and different glazes require different temperatures. Thus porcelain and stoneware are fired to much higher temperatures than ordinary pottery, and salt and alkaline glazes need a higher fire to mature than the ordinary lead glazes. When the required temperature has been reached—which nowadays is determined either by means of a pyrometer or with the help of pyrometric cones which melt at a given temperature and which are watched through a spy-hole (cf. fig. 40 where the cones are set up opposite the spy-hole in the door, and fig. 42 where the cones have melted)—the fire is gradually extinguished and the kiln left to cool slowly. Twelve hours for the firing and twelve for cooling is a rough estimate for the firing of an ordinary kiln. It is important not to hurry the process of cooling, as a too rapidly cooling fire may crack the ware or affect the glaze injuriously. The Greeks fired their pottery at a considerably lower temperature than potters do today. It seems to have been about 960° centigrade (corresponding to about cone 010) since any increase over this temperature causes a change in the color of the clay together with an additional contraction. When the kiln is finally opened comes the exciting moment of seeing what the fire has done with one’s products. In taking out the contents of the kiln, gloves and sticks are often useful for handling ware that is still too hot to touch. Invariably there will be surprises—what one has expected to be a great success often turns out a failure, and what one thought little of may become a rare thing of beauty. In the biscuit firing the adventures of the pot are comparatively few; it may crack or sag or warp, but as a rule the expected shape is maintained. But in the glaze firing so many elements enter in that even an experienced potter can never be sure of the result. The color may turn out a different shade from that desired; the glaze may unexpectedly be matt (dull) or too glossy; it may blister or peel or crack; it may be too thin or too thick. Such defects are almost invariably due to faulty composition of the clay or the glaze or to the conditions of firing. They can often be remedied by further glazings and firings; but quite often a pot on which much time and labor have been bestowed is hopelessly ruined. A good potter, however, will soon learn to bear such mishaps philosophically; and it is certainly true that one often learns much more from failures than from successes. Moreover, the element of uncertainty lends spice to the craft. A careful consideration of the modern processes of firing pottery described above will help us to settle the problems connected with the firing of Greek vases—for the action of fire on clay remains the same even though the kilns in use The chief problems which confront us in Athenian pottery are (1) the number of firings, (2) the interpretation of defects on Greek vases as injuries in the firing. Number of firings.Was Athenian pottery once or twice fired?[14] That is, was it decorated in leather-hard or in biscuit condition? This has been one of the most debated questions in Greek ceramics. Archaeologists often assume offhand a number On the other hand, it might be urged that if we assume that the decoration was executed in leather-hard condition, the vase painters whom we see depicted on Greek vases should be handling their pots with considerable care, and that this is hardly conveyed in the representations. On the Boston fragment, for instance, the painter is holding a There is, moreover, evidence which seems to settle this question beyond dispute. On a number of the Athenian vases there are dents such as can only have occurred while the vase was still in a leather-hard state. The mark of the object contact with which caused the dent is invariably over the black glaze (cf. fig. 45), showing clearly that the glaze must have been applied in leather-hard condition.[21] In some cases we find still adhering in the dents a little burnt The fragments of unfinished vases which have been found from time to time[24] have been used as evidence to prove several glaze fires; for they show fired vases at a definite stage The unfinished kylix in the collection of the Metropolitan Museum may shed light on this problem (fig. 47). It is not so fragmentary as the pieces in the other museums, being complete except for portions of the rim. The foot is very roughly turned (fig. 48), very different from the average kylix foot, as if it had not been worth while to spend The probability, therefore, is that Athenian pottery is once fired,[25] all ornamentation—both glaze and accessory colors[26]—being applied while the vase was in leather-hard condition; for in the case of the accessory colors also there would have been no advantage in an additional firing. Injuries in the firing.The action of the fire on the potter’s products was apparently as much an open question in Greek times as it is now. Practical experience must have gone a long way then as today; but full control could not be achieved. In forming an estimate of what proportion of the pottery was spoiled in the kiln we must remember that in our museums we are apt to encounter the survival of the fittest—what the potter considered worth preserving, what the Greek client deemed adequate to his need, and what the modern museum curator considers good enough for exhibition. But even in this selection we meet with a number of kiln mishaps, which apparently were so common that they were hardly noticed. When our eyes have become trained to observe such things, we shall note that in any collection of Greek vases there are many cases of warping and sagging, especially in the overhanging lips of the hydriai and amphorai.[27] There are The commonest injury to the glaze in the fire is its change into a brilliant red instead of the intended black. This can be observed on many vases, sometimes as a large spot (cf. fig. 49), other times as a less clearly defined variegation.[32] The cause was irregularity of fire, a jet of air passing through the kiln coming in contact with parts of the vases. Such red spots caused by jets of air coming in contact with the vases must not be confused with the very similar red spots which are due to the wearing off of the black glaze and the exposure underneath it of the ochre-tinted clay (cf. p. 58). Examination with a magnifying glass will show the difference: in one case the red is part of and level with the black glaze, in the other it is on a layer beneath the black glaze; in the former case the red will not come off when rubbed, in the latter it will. GLAZINGBesides shaping and firing a vase, a potter must understand the art of glazing, to many the most alluring part of the craft; this comprises both the preparation of the glaze and its application to the pot. A glaze is a chemical compound, known as a silicate, which upon firing becomes a glassy substance. It has three chief ingredients: (1) an oxide of lead, of lime, of alkali, etc., which forms the foundation of the glaze; (2) alumina and boron oxide, which regulate the behavior of the glaze in the fire; and (3) silica, which controls the fitting of the glaze to the body. Modern glazes are divided into two chief categories: lead glazes and leadless glazes. Of these the former are by far the more numerous; but alkaline glazes, tin enamels, etc., are also used, especially in studio potteries. In the preparation of a glaze the ingredients have first to be weighed out carefully in the required proportions; the mixture has then to be ground with water and sieved; and when the right thickness is attained (usually about the consistency of cream), the glaze is applied to the vase, which should first be soaked in water to saturation to prevent too rapid absorption. Gum tragacanth is used as a binder to make the glaze stick. The glaze can be applied in various ways—by dipping (fig. 50), by pouring (fig. 51), by the use of the brush (fig. The Athenian potter had no ambition to produce brilliant color effects in glazing. He was content with the one variety which he had brought to perfection—a thin, luminous glaze of a deep, velvety black color and of astonishing The glaze was, as I have endeavored to show (cf. pp. 37 ff.), applied to the vase in leather-hard condition. At that stage the clay still contains enough water to prevent too rapid absorption, and the glaze, therefore, runs in an easy, flowing How did the Greek painter apply the glaze to his pottery? We know that on the broader surfaces the brush was used, for brush marks are clearly visible in many cases.[40] When possible the backgrounds and horizontal bands were painted while the piece was rotating on the wheel; where a panel had to be reserved, the irregularity of free-hand brush work RED OCHRE WASHIn three statements of ancient writers the addition of red Archaeologists have assumed that this red ochre was mixed with the clay and that to it was due the deeper color of Athenian ware as compared, for instance, with the geometric. Thus in practically all our books on vases the preparation of the clay for the manufacture of Athenian vases is described somewhat as follows: “The clay having been thoroughly purified and washed, was then kneaded and brought to a consistency suitable for shaping it on the wheel. It was at this stage that other substances, chiefly a red earth (ochre = ??t??), were worked in with the clay to deepen the color.” First of all, it should be noted that if ochre is to be added to the clay it must be done long before the kneading stage, otherwise the red ochre will of course not mix evenly. The best time would be when the clay is dry, so that a definite proportion could be weighed out. But that is too obvious to need discussion. The question is, Does the addition of red ochre materially change the color of the clay? It may be interesting in this connection to record my experience in the matter. About three years ago I was asked to speak at a convention of modern potters meeting at the Metropolitan Museum of Art, on the subject of Greek vases. I thought that these potters would probably be What, then, do Pliny and Suidas mean when they speak of the addition of red ochre to Athenian pottery? A number of archaeologists have observed from time to time that Athenian vases, especially of the late red-figured period, show traces of a reddish pigment applied over the surface. Reichhold in his technical description of vases in FurtwÄngler und Reichhold, Griechische Vasenmalerei, frequently refers to it as “rÖtliche Lasur.”[44] Pottier ascribed it to a sort of varnish or lustre applied over the surface In the light of this experience let us again examine what Pliny and Suidas say. Pliny’s statement is sufficiently vague to make any interpretation possible; but Suidas’ use of the word ?ptes?a?, “to be dipped,” is illuminating. The clay could not have been “dipped” in a powdery or liquid Since the black glaze was probably applied to the leather-hard clay, the ochre wash must also have been added in that state. The leather-hard vase might have been dipped in an ochre solution or the ochre applied with a brush or rubbed into the surface as a powder. In order to make it adhere properly to the clay actual experiments have shown that by far the best results are obtained by giving the surface a good polish after the application of the ochre. The ochre is thereby actually incorporated with the clay and forms a good firm surface. If not so polished, it is powdery after firing and comes off easily. Experiments further showed that (1) red ochre applied in this manner on the red clay in leather-hard condition produced an effect identical with the red “wash” observable on the Athenian vases; (2) preliminary sketch lines engraved lightly with a blunt tool did not remove the ochre; (3) the ochre in no way interfered with the adhesion of the black glaze over it; (4) the ochre came off only a little at a time even when rubbed hard while wet. It is therefore only during the long processes of wear and time that the red ochre application has worn off. But even when it has entirely disappeared, it has stained the clay a deeper color—namely, the orangey hues which we see now; for the actual color of the clay is lighter and pinker, as any fracture will show.[52] Originally, however, we learn from our investigation, the red-figured Athenian vases had an even deeper and richer tint than they have now—approaching more nearly the color of copper. The general effect, therefore, must have been considerably more vivid than it is today, and to some this thought may not at first appeal. But we should remember that we are discovering also in other fields that the Greeks loved bright, intense color, not the faded tints that so many of their works present today. WERE ATHENIAN VASES MADE FOR EVERY-DAY USE?The theory has often been advanced that the painted black-figured and red-figured vases were made for decoration and for votive and funeral purposes, but not for actual use. Percy Gardner in his Grammar of Greek Art (p. 160) holds this view and gives as his reason that the painted vases were too fragile to be easily handled and too porous to contain liquid. Reichhold in FurtwÄngler und Reichhold, Griechische Vasenmalerei, Text, I, p. 82, and Skizzenbuch griechischer Meister, p. 10, is of the same opinion, and bases his assumption on the fact that a number of the vases show ancient rivet marks and could not therefore have served any practical purpose in such a condition; also that no ancient vases show signs of wear, which would have been unavoidable if they had been in daily use. Does our investigation of the technique of Athenian vases help to settle this question? Let us look first at the case in its broader aspects. Nobody can work long with Greek vases or other forms of Greek industrial art without being impressed with the wonderful combination of beauty and practical utility which these objects show. The Greek vases are not only finely proportioned, but each one is admirably adapted to its purpose. We need only try pouring from an oinochoË to see how easily the liquid flows without any danger of That the bulk of vases were made for votive purposes, there is no real evidence. Among the many sixth- and fifth-century inscriptions recording such offerings there are few relating to pottery vases. Nor is it conceivable that these vases were purely ornamental. We know that private houses in Athens were at that period excessively simple, consisting mostly of a courtyard and a few rooms opening on it, so that it is not likely that people surrounded themselves with a lot of useless ornaments; nor can we believe that in a period which, at least in the sixth century, was still one of strenuous endeavor, these vases were exported to all parts of the world merely as decorative bric-À-brac. Everything we know of Greek life at There is another consideration. Even if, from our modern point of view, we may hesitate to believe that a beautiful cup of Euphronios was used merely as a drinking vessel, where are we to draw the line? Any one who has worked in a museum or has excavated on fifth-century sites knows that besides the selected specimens exhibited in museum cases there are a large number of inferior examples, hastily decorated, which could hardly have been displayed as ornaments, but which are open to the same objections raised against the vases of better workmanship. And now let us examine these objections. First, the vases are supposed to be too porous to contain liquid. The fineness of the clay, the polish which was imparted to it, and perhaps the application of the ochre tended to reduce this porosity somewhat. In the course of time the deposit left by wine and oil would still further close the pores. In any case, experiments show that Athenian vases do hold liquids without any difficulty. The unglazed portions become damp, and a damp mark is left on the table if the foot is not glazed; but in the days before highly polished furniture there was no strong objection to that, and there was on the other hand a very real advantage. For it allows a certain amount of evaporation which would tend to cool the liquid—a very desirable thing in a warm climate The objection that Athenian pottery is fragile is easily disposed of. Actual handling of the vases will show that they are anything but fragile, in fact that they are remarkably strong. All those portions which would get special wear, such as handles and rims, are almost always stoutly made, more so than much of the china and earthenware and glass we use today. Occasionally, of course, we get a very thin and delicate example; and that would have to be handled with special care. Then, as regards the question of wear. Terracotta is, as a matter of fact, one of the most indestructible materials we have, and especially so when glazed. Glazed earthenware, consequently, even though in constant use shows little trace of wear. What little we should expect, a close inspection of Athenian vases will reveal. The black glaze, even when perfectly preserved on the exterior, is much worn on the interior of stamnoi or kraters (cf. fig. 57), where the liquid came in constant contact with the glaze, and the unglazed interiors of amphorai and hydriai are certainly not perfectly fresh and unused looking. It is also noteworthy that finely and poorly decorated vases are in the same condition in this respect. A comparison with the Corean pottery of the Korai period, 935-1392 A.D.,[55] which is known to have been made to serve merely as tomb furniture, is helpful. Lastly, regarding the argument about riveted vases, it is surely natural now and then, instead of throwing away a broken pot, to have it put together and make the best of it in its mended state. We do the same thing nowadays. At all events, the vase could still have been used to contain dry materials. Such Athenian vases with ancient rivet marks are in any case infrequent, and do not compare in number with the broken vases which have not been mended. Such considerations should once for all explode the theory that Athenian vases were not actually used; so that we can think of them, in the way that appeals to our imagination, as serving in the daily life of the Athenians and as adding to the enjoyment of that life, both by their beauty and by their usefulness. |
