esteemed by connoisseurs of old porcelain. It is peculiarly English, and stands unique in having technical assets not possessed by any other porcelain. This is something great to record to the honour of the English potter in his mastery of technique.

The New Ceramic Art.—The eighteenth century, in spite of the wars which shook the kingdoms of Europe to their foundations, showed a singular enthusiasm for the art of the potter. A reference to a table of the factory marks of European porcelain of that period will disclose the fact that most of the leading factories were under the auspices of royal or noble patrons whose arms or monograms were incorporated in the mark of the factory.

Kings, princes, electors, grand dukes, and margraves vied with each other in producing rival ware. The St. Petersburg factory had the cipher of the Emperor Paul. At Weesp, in Holland, Count Gronsveldt-Diepenbroek's factory, the works were handed over to the direction of a Protestant pastor. From Vienna with the mark of the Austrian arms, to La Haye with the design of the stork, the symbol of the city; from the arms of the Archbishop of Mayence and the cross and initials of the Prince Bishop of Fulda, to the design of Lille, the Manufacture Royale de Monseigneur le Dauphin with the crowned dolphin, a bewildering entanglement of royal marks and patrician ciphers is studded on china, to the confusion of collectors, adding zest to the art of the connoisseur.

The Great Secret.—The actual discovery of the composition of true porcelain by Böttger is interwoven with romance, and the betrayal of the secret processes of its manufacture at Meissen to the leading factories of Europe is a record filled with stirring incidents of the most piquant character. The story of young Böttger, the alchemist and inventor, is told in full by Professor Ernst Zimmermann, Keeper of the Royal Porcelain Collection at Dresden, Die Erfindung und Frühzeit des Meissner Porzellans, Berlin, 1908. The search for the philosopher's stone to transmute baser metals into gold had fascinated all chemists. Böttger was credited with more knowledge than he possessed, and he hastily quitted Berlin to avoid the too assiduous attentions of the King of Prussia. For years he wandered in Saxony, and finally claimed protection in 1701 from Frederick Augustus, Elector of Saxony. His life at the laboratory at Meissen, under Ehrenfried Walter von Tschirnhaus, who was a distinguished scientific scholar, was that of a guarded prisoner with a wonderful secret. Tschirnhaus, who was a good chemist, established a glass furnace and invented an ingenious burning mirror, and had essayed to make porcelain. But on the assumption that it was a vitrification, his results only led him to the production of a milky glass. A specimen of this milch glass is in the Japanese Palace at Dresden.

When Charles XII of Sweden invaded Saxony, Böttger and his workmen were hurried off to the impregnable fortress of Königstein, where a laboratory was erected. A year later he was back at Meissen conducting experiments and cheerfully exhorting the workmen. In 1709 he produced his true hard porcelain from natural earth obtained from Aue, near Schneeberg.

The most elaborate precautions were taken at Meissen to prevent the secret becoming known. The earth was delivered in sealed casks. It was in vain that an oath was exacted from each workman and written on the walls—"Silence until death" (Geheim bis ins grab). The punishment for betrayal was incarceration as a State prisoner in the fortress of Königsberg for life. The terrible silent conditions of the labour produced a longing on the part of the immured workmen to escape. And escape they did.

The Secret divulged.—In 1718, the year previous to Böttger's death Stolzel, the chief workman at Meissen, made his way to Vienna and proceeded to establish, under the direction of a Belgian named Claude Du Pasquier, a manufactory of hard porcelain. The factory was acquired for the State by the Empress Maria Theresa in 1744.

From Vienna a workman named Ringler carried the secret far and wide. His name is linked with the founding of several factories—at Höchst in 1740, at Frankenthal in 1754, where he became director, at Nymphenberg in 1756, where his aid was invoked, at Ludwigsberg (in Würtemberg) in 1758, and at Zurich in 1759.

The workmen of Höchst, in their turn, further divulged the secret. Bengraf, in 1750, carried the process to Fürstenberg, the factory under the patronage of the Duke of Brunswick.

In 1744 an imperial china factory was established at St. Petersburg by the Empress Elizabeth Petrowna, who employed workmen from Meissen, and in 1765, under the patronage of the Empress Catherine II, the works were enlarged.

There were two methods of obtaining the great secret of Meissen—by stealth and by experiment; most of the factories employed the former means. The attempts to arrive at the hard paste by experiment resulted in the establishment of many soft-paste factories. One remarkable instance of indefatigable industry is that of the chemist Pott, in the employ of the King of Prussia at Berlin, who endeavoured honestly to arrive at the nature of the composition of the Meissen body. He is credited with having made no fewer than thirty thousand experiments, and in so doing he contributed largely to the modern chemical knowledge of the effect of high temperatures on minerals.[3]

It is thus seen how great was the discovery of Böttger, of Meissen, and how far-reaching were the results of the manufacture of true porcelain in Saxony. A wild burst of enthusiasm followed which has been rarely equalled. Soldier-princes engaged in the wars which were waged in the German States turned aside to indulge in speculation concerning the new art. In 1717 about a hundred and fifty pieces of fine porcelain, many of them old Oriental, now at the Japanese Palace at Dresden, were acquired by Augustus the Strong of Saxony from the King of Prussia in exchange for a regiment of dragoons, without uniforms, horses, or arms.

When the vigilant Frederick the Great commenced the Seven Years' War, and on a sudden filled the electorate of Saxony with sixty thousand Prussian troops, Dresden was taken. It was in vain that the Queen of Poland, daughter of an emperor and mother-in-law of a dauphin, placed the secret State documents in her bedroom to avoid seizure. They were too valuable to Frederick, who had them forcibly removed, and by publishing them proved that he was to be assailed at once by Austria, France, Russia, Sweden, Saxony, and the Germanic body.

The factory of Meissen was depleted of material and models, and he transported artists and workmen to Berlin to found his factory there. Five hundred persons were engaged at this new factory, and in order to win commercial success he executed a master-stroke by framing a decree that all Jews in his kingdom must produce a voucher from the director of the factory that they had purchased a certain amount of the royal porcelain before permission would be granted to enable them to
