The water was periodically decanted until a stiff cake, of the consistency of pottery clay, was left. This was sliced up, discarding the coarse material at the bottom, and burned in the kiln. Wet grinding is comparatively energy-efficient, and so when good dry-grinding equipment became available, the wet process continued in

years a number of workers have turned their attention to a study of the grinding of clay in an attempt to elucidate a mechanism of the process and the nature of the resultant products. The pioneers in this field were Kelley et al. who investigated the grinding of bentonite in 1931 and the grinding of kaolinite in 1936.

Clay is manufactured in a wet or dry process. Grinding and drying of raw material is done before mixing with water and storaging on wet piles. Clay has a flaked or layered shape, a good affinity for water and a tendency towards high plasticity while being wet. After baking the clay converts into a ceramic material.
