In 1904 Armand Marseille from St. Petersburg founded the company manufacturing porcelain heads for dolls. Several years later production shifted to technical ceramics.
In 1913 the company was sold to Siemens - Schuckert AG in Berlin Siemensstadt.
Due to the ever increasing requirement for electricity in the 1920s the demand for technical porcelain for insulation and isolation applications rose significantly.
The introduction of new materials, like Steatite, and the expansion of capacity ensured the manufacture of more complex products. The plant in Neuhaus-Schierschnitz specialized in Steatite in 1958. Between 1965 and 1969 it was merged with the plants in Sonneberg and intergrated with the Kombinat Keramische Werke Hermsdorf.
The company was taken over by a trusteeship in 1989 and restructured into the stock company Tridelta AG. In 1993 the electro-ceramic production was outsourced and WWS Keramik Neuhaus GmbH was founded by means of a Management-Buy-Out.
