19th century Porcelain was the driving force of the industrialisation in this region, since
C. M. Hutschenreuther had discovered
kaolin somewhat north of Arzberg and set up his production in
Hohenberg an der Eger. In 1838,
Lorenz Christoph Äcker asked for the permission to establish a first
Porcellain-Fabrique in Arzberg which changed hands some times until, in 1884, it was acquired by
Carl Auvera (1856-1914), a grandson of
C. M. Hutschenreuther, and finally by the
C. M. Hutschenreuther AG, in 1919. In 1876,
Heinrich Schumann established the second one, inherited by his son
Carl Schumann. In 1887,
Christoph Schumann (1864-1916), Heinrich's younger son, founded a third factory, which he already in 1891 sold to Theodor Lehmann. ==Sister city==
