The 7 Stages of Clay - And a Forgotten Number 8
6. Bisqueware Stage of Clay. The bisque stage is when the clay is fired in the kiln between Cone 08 (1728F) and Cone 04 (1945F) to remove any chemically bonded water and impurities from the clay. This causes the clay to change permanently making it much harder but still porous enough to absorb the glazes nicely.

The composition of cement is proportioned here depending on the desired properties of the cement. Generally, limestone is 80% and remaining 20% is the clay.
Grinding Operation - an overview | ScienceDirect Topics
For surface grinding operations, the process parameters, i.e. the linear feed, the cross feed, and the depth of cut, have a direct influence on the roughness of the ground surface.Higher values of any of them would result in a higher material removal rate, and therefore, a higher rate of generation of thermal energy.
