This factory was founded in 1905 by Christoph Schumann, the brother of Carl Schumann the 1st (see Porzellanfabrik Carl Schumann) and his father-in-law Karl August Schreider, a wealthy land owner. In 1913 it already had 150 employees and specialized on utility ware including many reticulated porcelain items decorated in the Zwiebelmuster ("Blue Onion") and Strohblume ("Strawflower") styles. The company slowly expanded until it had around 400 employees in 1937. Nothing else is known about this company which went bankrupt in 1984 and following its closure in 1986 left behind an industrial ruin with lots of contaminated soil that had to be removed by the regional authorities under state funding between 1998 and 2005.
The different mark colors have no specific meaning and do not refer to quality grade or production period. Numeric additions to the marks represent internal quality assurance and workflow codes, like the responsible foreman, gilder, or decorator ID and are therefore irrelevant.
At least two different marks are known to state the year 1778 as founding year, however there is no indication in the company history whatsoever what this claim is supposed to be based upon. It is commonly believed to represent the year in which the Schreider family settled in the town of Schwarzenhammer.
Next to the relatively uncommon but easily recognizable domestic golden mark used on the York 7350 series, one will also find a dedicated red export mark, consisting of the crowned initials "PSS", standing for Porzellanfabrik Schumann & Schreider, see below.
