What are the differences between Zeolite, Bentonite, Pascalite, Montmorillonite, Illite, French Freen, Ormalite, & Pyrophyllite Clays?
According to http://mineral.galleries.com/minerals/silicate/clays.htm, Wikipedia and common geological knowledge: Illite is a member of the Clay-Mica Group of clays referred to as a Muscovite and is a main component of shale. It is abundant in potassium. It is commonly found as a component in other clays such as Bentonite & Montmorillonite, adding a potassium twist to those clays. French Green Clay is an Illite Clay. French Green Clay has recently received the most attention lately, due to the research performed by Geologist Lynda Williams, PhD of Arizona State University documenting the antibacterial properties of certain clays. Research in this area is ongoing and more will be published in time regarding her findings with other clays as well. Another spin off article on Lynda Williams’ research is entitled “French Muck”. Bentonite has had some difficulty in being classified properly due to the varying amounts of other clays that can make up the bulk of a Bentonite (often times contai
