The porcelain painting studio Sontag & Soehne was founded around 1812/1813 by Georg Heinrich Sontag in Geierstahl. Initially, they probably painted pipe bowls. Georg Heinrich Sontag died in 1848 and the company started to be managed by family members Ernst Renatus Sontag, Robert Meusel and Salomon Meisel.
Around 1855, Sontag & Soehne painted a significant proportion of the white porcelain produced in Wallendorf. At this time, Ernst Renatus Sontag owned a third of the Wallendorf factory. In 1865, the porcelain factory in Tettau was taken over by Sontag & Soehne. It was bought by Ernst's son, Wilhelm Sontag.
Robert Meusel died around 1870 and Ernst Renatus Sontag died in 1878. The shares in the Geierstahl porcelain painting company that belonged to Ernst were transferred to his son Eduard Sontag. Ernst's shares in the Wallendorf porcelain factory were in turn transferred to his son Robert. After Eduard's death, the company was probably run by the Meisel family.
Throughout its history, Sontag & Soehne decorated white porcelain from Wallendorf, later from Tettau and finally from Fraureuth. Only pieces from Fraureuth are marked with both the Fraureuth mark and the Sontag & Soehne mark. The porcelain blanks from Fraureuth were bought up after the company went bankrupt in 1926. Older porcelain decorated by Sontag & Soehne is most likely not marked by this porcelain painting company.
In 1930, the porcelain painting company Sontag & Soehne went bankrupt.
