4. Soil Formation 4 Parent Rock Residual soil Transported soil ~ in situ weathering (by physical & chemical agents) of parent rock ~ weathered and transported far away ~ formed by one of these three different processes 1) Igneous: formed by cooling of molten magma (lava) e.g., Granite, Basalt 2) Sedimentary: formed by gradual deposition, and in layers e.g., …
Besides, various affordable minerals and industrial wastes, such as aluminum sludge, coal fly ash, rice husk silica, coal gangue, sago waste, topaz sand, diatomite, bauxite, ball clay, and kaolin, have been employed as starting materials for the production of mullite ceramics [5]. Nevertheless, its synthesis from clay minerals remains the most ...

The ball clay:kaolin mix can be altered to change body plasticity without significantly affecting the maturing temperature. In North America, most commercial ball clays are mined in the southeastern US. Ball clay deposits are common and were laid by the action of slow moving water with an acidity that tended to flocculate and settle the clay.
Chemical composition and particle size are two useful indicators in choosing a replacement material. Always look for similarities in both when trying to substitute one material for another. Ask the ceramics supplier for a chemical analysis …
