K is for Kaolinite
Kaolinite is a clay mineral with some great properties. It absorbs water. This makes it a great filler in things like toothpaste, ice cream, and milk shakes. It doesn't have to be listed as an ingredient because it is not a food.
One way of testing for kaolinite in the field is to place a fresh piece to your tongue. If it is kaolinite, it will stick to your tongue as it absorbs the moisture. Pieces that weigh over a pound can actually be hung from your tongue, if you dare. It is also used in making ceramics, medicine, coated papers, cosmetics, light bulbs and medical bandages.
