THE soft paste of SÈvres, even during the period of the fifties and sixties, when the most exquisite ware was being made, seems always to have been regarded somewhat as a make-shift, to be employed until the materials for making a true porcelain should be discovered in France. For it was the ignorance of the true nature of kaolin, and where to look for it, that so fortunately delayed its introduction at SÈvres. As early as the Vincennes days, one of the Hannongs of Strassburg had offered to sell his secret, and this offer was repeated at a later time by himself and by his son. At SÈvres, before 1760, two German workmen were retained to teach the Saxon process, but the materials had still to be obtained from Germany.

Meantime Macquer, who had succeeded to the post of scientific adviser on the death of Hellot, had been experimenting on his own account, and above all encouraging others to search for the precious white earth within French territory. At length, in 1760, some samples were sent from AlenÇon, from which a true porcelain was made, but of poor quality and of a grey colour. Outside the SÈvres works the younger Hannong had set up a factory at Vincennes, and the Comte de Brancas Lauraguais, whom we shall meet with again in England, had by 1764 begun his experiments and his search after deposits of kaolin. There still exist a few portrait-medallions moulded in hard porcelain, which, on the ground of the letters B. L. engraved on the back, have been attributed to that energetic nobleman.

The introduction, however, of the hard-paste porcelain at SÈvres dates from the discovery, in 1768, at Saint-Yrieix, near Limoges, of those famous deposits of kaolin which have ever since that time been the main resource of the French porcelain industry.[194] Before the end of the year 1769 Macquer was able to show to the king the first samples of this new ware. The hard paste made for some years after this date was not of the ‘severe’ type adopted later on. Not only did it contain as much as 9 per cent. of lime, but, the kaolin employed being less pure, contained probably a good deal of mica—in fact, this first type of French hard paste approached in composition that of the Chinese. It is even more important to note that the glaze used at the same time was of an entirely different nature from the pure felspathic covering afterwards adopted. It was composed of Fontainebleau sand 40 per cent., potsherds of hard porcelain 48 per cent., and chalk 12 per cent. As a result, it was possible to decorate the surface with brilliant translucent enamels of some thickness.

It was the introduction of the felspathic glaze in 1780 that gave the final blow to the effective decoration of SÈvres porcelain. This glaze is made by simply fusing a natural rock (pegmatite) consisting of a mixture of potash felspar with a small quantity of quartz. The ease with which this glaze can be prepared, its hardness and uniformity of surface, led to its universal adoption not only at SÈvres but in the porcelain works of the Limoges district that have for the last hundred years supplied France with ordinary domestic wares—for such use its hardness renders it eminently suitable. But, as we have said, this combination of refractory paste and hard glaze is incompatible with any brilliancy of decorative effect, the enamel colours are quite unable to incorporate themselves with subjacent glaze, they lie dull and dead on the surface, and the faults of the German porcelain are exaggerated.

So with the paste, a much harder and more refractory type was introduced at the beginning of the next century, and (apart from the recent partial introduction of a milder type for special purposes) this type has remained in use to the present day. The lime in Brongniart’s new paste was reduced to 5 per cent., while the amount of kaolin (65 per cent.) is probably greater than in any other porcelain. There has been a reaction lately at SÈvres against this refractory ware, but the old formulas are still employed for the porcelain made for practical domestic use. When, however, brilliancy of effect and artistic decoration are aimed at, a completely new type both of paste and glaze has been in use since the year 1880, and concomitantly with the imitation of the Chinese monochrome wares, an attempt has been made to follow as closely as possible the pastes and glazes of the Chinese. M. Vogt, the present technical director at SÈvres, who has had so much to do with these changes, gives the following formula for the composition of the new porcelain: kaolin 38 per cent., felspar 38 per cent., quartz 24 per cent. The lime, it will be seen, has been completely eliminated from the paste; on the other hand, the glaze contains as much as 33 per cent. of the Craie de Bougival.

It would be a dreary task to enter with any detail into the history of the SÈvres works during the hundred years following the first introduction of the hard paste. This period is associated in most minds with the colossal vases that are to be found in so many of the palaces and museums of Europe. To judge from these examples, it would seem that the chief object both of the design and the decoration was to conceal as far as possible the nature of the material used in their composition. You have first to persuade yourself that you are looking at something made of porcelain: once convinced of this, you marvel at the technical difficulties that have been overcome in its manufacture, but what it never even occurs to one to look for in these monstrous vases, is any trace of that beauty of surface and brilliancy of decoration that we are accustomed to associate with the substance of which they are composed.

The ‘Medici Vase’ now in the Louvre is probably the earliest of this long series. This vase dates from the year 1783, and it is nearly seven feet in height. But it was in the pseudo-classical style of the empire, when encouraged by Napoleon’s love of the gigantic, and by his desire ‘À faire parler la porcelaine,’[195] that this new application of porcelain found its full expression. It is then that we find vases, candelabra, surtouts de table and clocks, in styles distinguished as Egyptian, Etruscan, Imperial, and Olympian. After this we can follow the decline of taste in the succeeding rÉgimes till, with the total extinction of all feeling for harmony of colour and unity of composition, we are landed—in the reign of the ‘bourgeois king’—in the style or absence of style which is the French equivalent of our ‘Early Victorian.’

There is one name above all others that is associated, at SÈvres, with this long period, that of Alexandre Brongniart, who was director of the works from the year 1804 until his death in 1847. The son of a well-known architect, and himself a fellow-worker with Cuvier, he attained some distinction both as a geologist and as a chemist. It was indeed from the point of view of a man of science that he approached the subject of ceramics,—as a geologist to examine the position and stratigraphical relation of any material suitable for fictile purposes, as a chemist to analyse these materials and to discover fresh metallic combinations suitable for glazes and enamels.

It was at this time, and chiefly under the influence of Brongniart,[196] that the palette of the enameller was enlarged by the introduction of so many new colours, the employment of which gives a new cachet to the decoration of the nineteenth century. Perhaps the most important advance was in the employment of oxide of zinc in the flux, by means of which the colours of many metallic oxides are developed and sometimes altered. The green derived from chromium is essentially a nineteenth century colour, and as it resists the highest temperature this green can be used, like the cobalt blue, as an under-glaze colour. From the chromate of lead an orange-red is obtained—the rouge cornalia, a crude and dangerous colour, and one that does not withstand high temperatures. An orange-yellow from uranium, and a deep and uniform black from iridium, were also introduced at this time or not long afterwards. The ‘English pink,’ the lilac tint so extensively used in the transfer-printing of earthenware, was successfully imitated by adding a small quantity of oxide of chromium to a flux containing oxides of tin, lime, and alumina. The celadon green of SÈvres is derived, not from the protoxide of iron, but from the sesqui-oxide of chromium, with the addition of a minute quantity of copper.

Brongniart’s great work, the TraitÉ des Arts CÉramiques, still remains our main authority on the technical and scientific side of the art of the potter, and it was he who, by establishing the museum and organising the laboratories at SÈvres, made that town a centre for all who are interested not only in the special branch of porcelain, but in the whole field of ceramic art. The position established by him has been well maintained by his successors, by SalvÉtat, by Ebelmen, by Deck, and at the present time by MM. Lauth and Vogt on the technical side—above all by Édouard Garnier, the present director of the SÈvres Museum.[197] These men have succeeded, in spite of much opposition, in again bringing the national manufactory of porcelain at least on to a level with the artistic movement of the day.

In tracing the history of the SÈvres porcelain during the last hundred years and more we can find at least one interesting aspect—we can follow the steps by which the ware has responded to the social and political changes that have followed one another in France during that time. The affectation of simple and homely tastes, and the sentimental tone fashionable in society during the years preceding the Revolution, are reflected in both the forms and the painting of the ware then made. The classical spirit that already in the time of Louis xvi. had found a place alongside of these idyllic aspirations somewhat later, under the lead of David, ruled every form of art. The various phases of the Revolution are reflected in the decoration of the porcelain, which even became a means of political propaganda. At the HÔtel Carnavalet, the museum at Paris consecrated to the history of the city, the political changes of this period may be traced in a series of plates and cups, some of them of SÈvres porcelain, decorated with emblems and allegorical figures relating first to the liberal monarchy of the early years of the Revolution, and then in the sterner days of the Convention (when indeed the existence of the works was only saved by the presence of mind of the minister ParÉ) to the patriotic efforts of the leaders, and to the successes of the republican armies. Portraits of the heroes of the national assemblies and of the clubs, surmounted by caps of liberty and framed in arrangements of pikes and drums, replaced the nymphs and flowers of an earlier period, and even the guillotine, it is said, has found a place in the decoration. A few years later the military element was even more predominant. Eagles and thunderbolts, surrounded by trophies of war, battle-scenes and the entry into Paris of the victorious legions, commemorate the conquests of Napoleon.

After the Restoration the decoration of the gigantic vases, each new one overtopping its predecessor, became more and more pictorial. To obtain a better field for this pictorial display the greatest pains were taken to produce large plaques of porcelain, some as much as four feet in length, on which a school of accomplished artists painted laborious reproductions of famous pictures, ancient and modern. Not a few of these enamel-painters, at this time, came from Geneva, and some of the ablest were ladies. Many remarkable specimens of this misdirected skill may be seen in the SÈvres Museum, and also in a room of the picture-gallery at Turin.

Under the republican rÉgime that succeeded the revolution of 1848, it was again proposed for a moment to sever the connection with the State, but with the establishment of the second empire a fresh life was given to the manufactory, on the appointment of Dieterle, an artist of repute, to the directorship. Some new developments were now attempted, especially in the introduction of coloured pastes. It was only after many fruitless attempts that any results were obtained by this new system. It is indeed a process quite foreign to the nature of porcelain, and even when technically successful the result is far from satisfactory. At a later time, however, the experience gained by the experiments of SalvÉtat enabled a potter of great skill and some feeling for art to employ the coloured pastes with greater simplicity and better effect. M. Solon, since so well known in England, was the most successful worker in this material. The decoration in his hands took the form of a white slip, or barbotine, laid on a coloured ground. After firing, the light and shade of the design is brought out by the varying thickness of the now translucent coating, which allows more or less of the coloured ground to be seen through it. In spite of its delicacy and refinement the effect of this work is somewhat effete, both in style and colour. In inferior hands, working with poorer material, the result is deplorable.

At the present time, after experiments with many materials—the crystalline glazes made with bismuth were at one time in favour—it is to the production of artistic effects by means of single glazes that the greatest attention is given at SÈvres, following more or less in the lines of the flambÉ wares of China. Not long since, a proposal was again made in the Chamber of Deputies that the support of the Government should be withdrawn from the factory. It is said that a timely report in an English paper to the effect that, in such a case, the works would be run by an Anglo-American syndicate, had not a little to do with the defeat of this motion.

Lesser Parisian Factories of Hard Paste.—In spite of the numerous edicts and proclamations by which it was attempted to maintain the monopoly of the royal works at SÈvres, there were in Paris, in the time of Louis xvi., a number of private factories, some of them under the patronage of members of the royal family.

It was in Paris that Brancas Lauraguais, as early as 1758, made his experiments with kaolin, and here, in the Saint-Lazare district, one of the Hannong family (Pierre Antoine, of the third generation, the same who had lately failed at Vincennes) made porcelain after the German style, perhaps before 1770. These works were patronised at a later day by the king’s brother, the Comte d’Artois.

Again, in 1773, one LocrÉ started in the Rue Fontaine au Roi the ‘manufacture de porcelaine Allemande de la Courtille.’ His marks of arrows (Pl. d. 59), torches, or later, ears of wheat, crossed in imitation of the Saxon swords, are found on ware of some artistic merit.

But perhaps the most remarkable of the Parisian factories was that started at Clignancourt, in 1775, by Pierre Deruelle, under the powerful protection of Monsieur (the king’s brother, afterwards Louis xviii.). The royal edicts (as indeed was often the case elsewhere) against the use of gold were ignored in this case, and the SÈvres ware—the simpler forms then in fashion—was cleverly imitated. The earlier mark, a windmill (Pl. d. 61), pointed to the famous moulin on the neighbouring Montmartre. At a later time the letter M, under a crown, referred to the royal patron.

The queen herself took under her patronage the factory started in 1778 by Leboeuf in the Rue Thiroux. This is the ‘Porcelaine de la Reine,’ marked with the letter A under a crown (Pl. d. 62), often decorated with leaves and little sprigs of the barbeau, the cornflower, then so much in fashion. These flowers, indeed, may be found on many other wares, English and French, about this time.

The Duc d’AngoulÊme was the patron of the works started in 1780, in the Rue de Bondy. It is noteworthy that this factory survived, still under the original founders, Guerhard and Dihl, to the days of Louis xviii. Dihl was, as it were, a forerunner of Brongniart, being the first potter in France to employ the newly discovered colours derived from rarer metallic bases. The Rue de Bondy factory had also the credit of producing elaborate copies of pictures on plaques of porcelain before such things were attempted at SÈvres.

The factory established in 1784 at the Pont aux Choux is chiefly remarkable for the patronage of the Duc d’OrlÉans, Philippe ÉgalitÉ. Starting with the brother of Louis xiv., whose arms are found on gigantic vases of ‘old Japan,’ this was the fifth member of the Orleans family who had interested himself with porcelain, in one way or another.

I have only mentioned a few of the more important Parisian factories. Franks, in his Catalogue of Continental Porcelain, gives a list of seventeen works. Examples of most of these may be found either in the Franks collection or in that of Mr. Fitzhenry.

After the Restoration the work done in Paris became more and more confined to the decoration of porcelain made elsewhere. A special industry—for such it may well be called—was the imitation of older wares, both Oriental and European. For this somewhat ambiguous work the Samson family has acquired a European reputation.

At the present day many more or less amateur potter-artists are working in Paris. Specimens of their work may be studied in the yearly salons. It is no uncommon thing to see—in the neighbourhood of the PanthÉon, for instance—a notice in a window pointing out to those interested, that a kiln for porcelain or fayence will be fired at such and such a date.

During the last hundred years Limoges has become more and more the centre of the porcelain industry of France. A very hard, refractory porcelain is here made from the excellent kaolin of Saint-Yrieix, and this ware not only occupies in France the position of our Staffordshire earthenware and semi-porcelain, but competes with these wares in the markets of the world. One of the largest works was started some years ago with American capital, and the United States, until lately, drew their principal supplies of porcelain from this district.[198] It is to a chemist attached to one of these factories, to M. Dubreuil, that we are indebted for our best account of the technical and chemical processes employed at the present day in the manufacture and decoration of porcelain (see the work quoted on p. 15). At Limoges there is a ceramic museum, the most important in France after that at SÈvres, the contents of which have been described by M. E. Garnier in a catalogue which, as far as continental porcelain is concerned, has, so far, no rival.[199]
