Clay manufacturing | Lhoist - Minerals and lime producer
Clay manufacturing can be either via a dry or wet/slurry process. Manufacture is comprised of a number of phases; extraction, blending (where necessary), crushing and drying. Each stage requires certain competencies and machinery to ensure that we always offer the most optimum product for each application. Clay is tested regularly throughout the manufacturing process to ensure
Steps in the Ceramics Process
Wedging is the process of mixing the clay by hand by rotating and pressing a clay ball on a table. The purpose is to thoroughly homogenize the clay and to remove all air bubbles. This is particularly important, as the presence of air bubbles in the clay will result in explosions in the kiln as the air pockets expand and burst.

Clay fired at this temperature still retains its porosity however. The porosity of a material refers to its ability to absorb a liquid. The liquid part of glaze, in this case water, is absorbed by the porous bisque ware, and the glassy materials in the glaze are left deposited on the surface of the bisque ware. ...

Introducing the unit. This unit provides an opportunity for learners to think of materials in terms of the distinctions between raw and processed materials. It is also an opportunity to link to Indigenous Knowledge when dealing with traditional methods of processing materials, and to draw learners attention to the fact that many of these traditional methods of processing are still used today.
