Kaolinite: The clay mineral kaolinite information and pictures
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.

Kaolinite - Wikipedia
The word kaolin is now used as a loose trade and geologic term to refer to white clayey rock that is predominantly composed of Kaolin Group (khandite) minerals. The most common constituent is the mineral kaolinite. Kaolinite is a layered silocate made of alternating sheets of octahedrally coordinated aluminum and tetrahedrally coordinated silicon that are bonded by hydroxyl groups.
