The word 'potash' refers to potassium compounds and materials which are potassium bearing. A mineral is defined as a naturally occurring inorganic crystalline solid with a definite chemical composition; therefore, potash is not a mineral as such, and is not a member of a mineral group.
Kaolinite is a clay mineral with the chemical formula of Al2Si2O5(OH)4. It is composed of the elements silicon, aluminum, oxygen and hydrogen. Rocks that are rich in kaolinite are called kaolin.
