Our product range covers raw and ground clays comprising 20-43% Al₂O₃ and firing colours ranging from cream-white to yellow and red. Key markets are manufacturers of structural ceramics and refractories.
Chamottes specified according to refractoriness, porosity, thermal expansion, firing colour and purity as well as grain size for refractories, fine fireclay sanitary ware and structural ceramics.
Pegmatite is a white-firing basic raw material for porcelain, sanitary ware, wall and floor tiles and clinkers. Washed potassium feldspathic sand is also introduced to roofing tiles as shorting material or as an Al₂O₃ source in glass mixtures.
Our fine-crystalline soapstone is ideally suitable for steatite and cordierite bodies. If calcined, it has particularly favourable effects in extruded products. It is used mainly in insulating components or in honeycombs as heat exchangers.
Crumbly bodies for refractories, structural ceramics as well as plastically shaped stove tiles and earthenware.
Finest-ground mineral products serve new purposes ...

Our family-owned business has involved in the extraction and processing of high-quality raw materials since 1921 .
Adolf Gottfried Tonwerke GmbH and Gottfried Feldspat GmbH are situated in Großheirath, Germany, south of the city of Coburg.
The plant where our clays, chamottes, soapstone and ceramic bodies are extracted and prepared is located in Großheirath. Each year more than
100,000 tons of different raw materials are processed in different qualities for
a wide range of applications. Gottfried ranges among the leading manufacturers of chamotte in Europe.
White-firing feldspathic sand, also referred to as pegmatite, is extracted and worked in Freihung/Thansüß, Germany, north-east of the city of Amberg.
To meet the increasing demands of our customers, we integrate high-quality raw materials from other suppliers in our product range.
Experienced engineers work in collaboration with our customers to develop raw material solutions and services made to measure.
Our company is certified in accordance with ISO 9001. The own laboratory guarantees high standards of product quality as well as compliance to agreed specifications.
Clay reserves in our deposits are safe for the next decades and we are able to guarantee security of supply.
We are committed to efficient and sustainable working processes; therefore we consider it a matter of course to integrate our mining facilities into the environment.
Our business field building materials offers a complete range of structural ceramics. When it comes to mineral sealing, Gottfried delivers clays, granulates and plastic elements. We also offer filler soil and accept excavated soil and builder's rubble for recycling.
