Note 155 — Chapter XV · THE HARD-PASTE PORCELAIN OF GERMANY
Reading edition
In a contemporary German pamphlet, which I only know from a French translation (Secret des Vrais Porcelaines de la Chine et de Saxe, Paris, 1752), a certain ‘spath alkalin’ is mentioned as an important element in Saxon porcelain, and this substance is identified with the petuntse of the Père D’Entrecolles.
