STEPHAN SCHMIDT KG: 75 Years of Expertise in Clay

STEPHAN SCHMIDT KG was founded by Stephan Schmidt in 1947, and today employs around 200
people in seven companies in Germany and other countries. It supplies speciality clays processed to highquality
products for all relevant ceramic applications as well as competent, clay-based system solutions
outside ceramics. Basis for its wide-ranging product portfolio is the extraction of tertiary clays from surface
mines in the Westerwald and Kamenz regions of Germany, where kaolins are also extracted (approx
1,6 Mt/a at 20 opencast mines). The raw material concepts with consistent quality are used in all areas
of ceramics: in demanding ceramic sanitaryware production, in high-quality tile concepts, for special applications
in heavy clay ceramics, for unshaped refractories as well as for enamels, engobes and glazes,
but also stoneware pipes and electrical porcelain. In addition, clay-based mixes, pellets and granulates are
used in a number of innovative applications in the ACM – Advanced Clay Minerals Business Unit (fillers/
additives, substrates, building materials, concrete-mortar-cement systems, well construction and drilling
industry, landfill construction and water management). The Group exports around 70 % of its products
to over 40 countries in the world.
In the run-up to the company’s anniversary year, at the meeting of German Ceramic Society’s Raw Materials
Committee, we were able to talk to Günther Schmidt (GS) – second generation of the founding family
– and Stephan Schmidt junior (StS) – third generation – about the company’s development.
