Processing Of Clay And Ceramics | Kofa Study

The stages in the processing of ceramics are essentially the same, as the stages in the processing of clay. To use clay in making any item, four different processes are involved. They are: 1. Excavation of Clay/Clay Preparation: Clay is usually excavated from the earth with a shovel. The clay is then processed, so as to remove air bubbles and ...

Structural clay products | Britannica

Structural clay products, ceramic products intended for use in building construction. Typical structural clay products are building brick, paving brick, terra-cotta facing tile, roofing tile, and drainage pipe. These objects are made from commonly occurring natural materials, which are mixed with

Ceramic technology: how to recognize clay processing ...

The issue of clay processing concerns both provenance and techno-functional ceramic investigations. In the former, the compositional/textural modification of clay alters the petrofacies expressed by the ceramic body and causes a change from the raw material in terms of bulk chemical and mineralogical composition and petrographical features as well.
