In regard to Müller's technical achievements, they stand to this day as a permanent record of his mastery of his art. The new body which he invented and called "virgin paste" is of a clear dazzling white, and is covered with a glaze transparent and smooth as polished crystal, tinted with the green of the sea; this glaze enhanced the beauty of the porcelain. Considering the impure materials then available, and the primitive working methods (for instance, fuel used at that time was wood, in poles 10 feet long of pine and fir), the perfection and beauty of the results demand profound admiration. Even with the aid of modern technology and chemistry it has not yet been found possible at the factory to produce porcelain equal in every respect to the old Müller period.

Perforated cover surmounted by gilded pine-cone ornament.] The diverse character of the output was stupendous. It was rich in design, varied and original in invention, virile in modelling, and national in spirit. The beautiful body invented by Müller had its decoration with his perfected overglaze colours, green and blue and purple. In regard to gilding, the artistic ideal seems to have been attained. It is not possible to convey as illustrations in this volume the extraordinary variety and beauty exhibited in this field. In the cups and saucers herein illustrated, the fine quality of the designs is lost in translation, but these borders of deep blue enriched with gilded designs of the most exquisite character are something to marvel at in connection with the work of the Müller period. The creations of the factory cover a wide range. The versatility of the modellers and the artists is pronouncedly marked. It bespeaks a great and prolific period when ideas were not lacking. Evidently there was no great searching after novelty, the gold was not beaten thin, apparently there was a profusion of intellectual force behind the factory. The difference is noticeable as soon as the great period is passed, when one falls on barren ways and thinly eked out inventions, the long years of the dreary twilight.
