  • Kaolinite

    Kaolinite is a clay mineral, with a soft consistency and earthy texture. It is easily broken and can be molded or shaped, especially when wet. Kaolinite is a lackluster and uninteresting mineral on its own, but it occasionally forms interesting pseudomorphs, especially after feldspars. It is also a common accessory to other minerals, including gem crystals in decomposing feldspar pegmatites.
