For the sake of convenient memory, I've divided Meissen into four periods:

1710-1763, the beginning period

1763-1820, the Academy (with a point), the Marcolini period, and the clay exchange period around 1820

1820-1924, Blur period and Sword hilt period

1924 -- present, Pfeiffer period, early postwar period, and modern era.

Have you own all porcelains of different Mason bottoms?
