Russia.—Peter the Great is said to have projected a porcelain factory at the suggestion of his ally Augustus the Third of Saxony, but the scheme was not carried into execution until the days of the empress Elizabeth. Catherine II. subsidized the work in prodigal fashion, but although she brought over French artists, the Russian porcelain more closely resembles its German than its French prototype. In the early years of the 19th century the imperial Russian factory followed the example of Sèvres in producing costly dinner services and extravagant vases of large dimensions.
Small independent factories were started in the neighbourhood of Moscow: one by an Englishman named Gardner about 1780, and another by A. Popoff. Besides producing ordinary table ware these Moscow factories sent forth a considerable number of statuettes, the most interesting being those representing Russian peasant types.
Hungary.—The one Hungarian porcelain factory of note is that at Herend, which was founded about 1830 by Moritz Fischer. At this factory copies of oriental porcelain were made that have deceived many collectors, though the pieces are usually impressed with the word “Herend” in the paste.
Switzerland.—Little porcelain has been produced in Switzerland, and considering the geographical position of the country it seems natural that porcelain of the German type should have been made at Zurich and of the French type at Nyon on the lake of Geneva, but these productions are of no particular importance.

French Porcelains.—The beginnings of French porcelain at Rouen and St Cloud have already been mentioned, as they preceded Böttger’s discovery of true porcelain; but as nothing was known in France of the methods and materials used by the German porcelain makers, the artificial or glassy porcelain held sway in France through the greater part of the 18th century. The next important factory after St Cloud was that founded at Chantilly about 1725 under the patronage of the Prince de Condé, an enthusiastic collector of Chinese and Japanese porcelains. One distinctive feature of the Chantilly porcelain is its imitation of the Japanese Imari wares of the 17th century, especially those bearing delicate patterns in the Kakiemon style. This imitation was not confined to the decoration alone, but great efforts were made to reproduce the delicious tender whiteness of the original ware, by covering the body of the soft porcelain with a coating of the tin-enamel used by the French faience makers. Similar imitation of the Kakiemon style of decoration became the rage all over Europe, and was largely followed at Meissen and in England as well as in France; but no European imitations equalled those of the famous Chantilly ware.
Other porcelain factories were started at Mennecy-Villeroy and at Lille, but the most important French factory was that founded at Vincennes about 1740, not only because of the many beautiful pieces produced there, but also because the works was taken under the direct patronage of the king in 1753 and was transferred to Sèvres in 1756, becoming ultimately the most important porcelain factory in Europe.
Fortunately we have documentary information of the exact composition of the artificial porcelain (pâte tendre) of Sèvres, and a brief account of its manufacture will serve to explain how all the glassy porcelains of Europe were made. The potter commenced by preparing a glass or frit, melting together pure sand, alum, sea-salt, gypsum, soda and nitre. The clear portions of this frit were powdered and washed with boiling water, and the working clay was compounded by adding to such powdered frit a small quantity of chalky clay or marl and sometimes pure chalk as well. This mixture was ground in water until the fluid was as fine as cream, and it was then boiled to a thick paste which was so little plastic in itself that black soap or parchment size was added to it to give it enough plasticity for the workman to be able to shape it. Vases and other pieces were made from this paste by pressing cakes of it in plaster moulds of considerable thickness. After pressing, the pieces were dried and were then either turned on a lathe or rubbed down with sand-paper to reduce them to sufficient thinness; while handles, spouts or other ornaments in relief were applied with a lute of slip, as is customary with every other species of pottery. The fragile objects were then fired into what is known as the “biscuit” condition; the most difficult part of the whole process. During this firing the pieces frequently went out of shape because of the excessive shrinkage of the material and its tendency to soften as it approached the melting point of the frit. Consequently an elaborate system of “propping” the pieces had to be resorted to, and even then a very large proportion became deformed. When the porcelain was drawn from the oven after the first firing, the supports were removed and the pieces were rubbed with sand to clean the surface, and were then coated with glaze by sprinkling with a brush; the glaze being a fusible glass very rich in lead. The glaze coat was melted by refiring the piece at a lower temperature; and it was frequently necessary to repeat this process several times in order to get a perfectly even and brilliant result. The difficulties of such a process were enormous, and it was only by the financial support of wealthy patrons, or of the state, that such a method of manufacture was ever carried on for any length of time. At its best the material is an exceedingly beautiful one, lending itself especially to decoration in on-glaze colours, and the pieces produced at Vincennes and at Sèvres, between 1745 and 1770 or thereabouts, form a distinct class by themselves. Skilful chemists like Hellot and Macquer were employed to direct the operations, and many beautiful ground colours, such as the famous gros-bleu, bleu de roi, rose Pompadour, pea-green and apple-green were invented.

Sèvres Porcelains.—The forms of the Sèvres porcelain are exceedingly varied. Many of the older shapes were designed by Duplessis, the king’s silversmith, and, as is perhaps natural, are more proper to metal than to pottery; but the French glassy porcelain is such an artificial material in every respect that such a point should not be strained too far. Owing to the want of plasticity in the paste the pieces were always made in moulds of plaster of Paris, while in many cases they were moulded in separate parts and these united together with metal screws or mounted in bands of chased ormolu. Table services made for actual use were usually painted on a plain white ground with the full palette of on-glaze colours (or enamels) and much rich gilding. The decorative pieces such as vases, candelabra, jardinières, &c., were decorated in a much more sumptuous fashion by covering the greater part of the piece with a ground of one of the rich enamel colours previously mentioned, reserving only panels in white on which delicate miniature-like decorations of the most varied kind were subsequently painted and fired (see fig. 52; and examples of Sèvres, Plate IX.). Such collections as the Wallace at Hertford House, or the Jones Bequest in the Victoria and Albert Museum, show at once the variety and perfection to which the work attained.
