Clays that have been transported by water from the site of their primary alteration and settled into layers. They are classified according to the geological period in which they were formed. Nature purifies these clay mechanically, removing gravel and sand, but contaminates them chemically or at the ultimate particle level, adding iron and fluxes. Vast deposits of secondary clays can be found in many places and materials having a wide range of properties can layer right next to each other. Ball clays, earthenwares and stonewares are secondary clays.
