It should be born in mind that this is a overall clay composition. When we compare the representations of a clay composition in both tables, we notice that chemists apply the existing nomenclature rules (chapter 3, Chemistry). Furthermore the above represention proves that clay contains a number of silicate minerals. The structure of these silicate minerals and of quartz was already discussed in the chapter on Geology and Minerology. In the next paragraph we will concentrate on a certain group of silicates, the so-called clay minerals. Without these minerals clay would not possess its specific clay properties. 

A pottery glaze is a mixture of chemical compounds. When the glaze is heated, chemical changes take place. As a potter works with clay, the clay properties (its elasticity, its color, its texture) change as chemical changes take place within the clay structure. 

The formation of three-dimensional polymer networks during the synthesis process has long been an important subject in polymer chemistry and physics [63-66]. The mechanism of formation of the organic (polymer)-inorganic (clay) network structure of NC gels was elucidated on the basis of changes in viscosity, optical transparency, XRD, and mechanical properties [39]. 

This chapter will provide only a brief description of clay mineral structures and properties, concentrating on those relevant to catalytic applications. There...

As has been shown by Fieldes and Schofield [1960] and Fieldes [1962], aluminum in tetrahedral coordination has distinctive properties which give rise to active sites on allophane. These properties are related to the nature of the sites that may arise at the edges of a crystal or of a somewhat ordered array of molecules such as may occur in allophane. Fieldes and Schofield discuss the various types of fractured bonds that may be found on clay mineral structures. The fracture of most interest is... 

Soil physical properties most likely to be altered by biomass burning are soil structure, soil wettability, and clay mineralogy (Table HI) (43). The destruction of organic matter results in losses of soil structure, increases in bulk density, diminished aggregate stability and decreases in macropore space (44).
