Clay is the finest grained fraction of the soil, and it comprises very fine minerals composed of hydrous silicates called "clay minerals".
According to him, clay is an earthy substance consisting chiefly of hydrous aluminium silicates with colloidal material and specks of rock fragments, which generally become plastic when wet and stone-like when fired.
clays are hydrous aluminium silicates of a great many mineral species, containing varying proportions of impurities.
These are the nanometre-sized products of decomposition by weathering of primary silicate minerals.
All clay minerals (some of which are similar enough to form broad groups) are essentially hydrous aluminium silicates, but they show variations in mineralogy, in chemical composition and in crystal form.،Clay is the finest grained fraction of the soil, and it comprises very fine minerals composed of hydrous silicates called "clay minerals".
