* Bentonite is a type of clay often used in cosmetics and skincare. It has absorbent and soothing properties.
* Magma is a thick, viscous mixture, often used in a geological context.
* Calamine lotion is a topical medication containing calamine (zinc oxide and ferric oxide) to soothe and relieve itching and irritation.
Bentonite is not "prepared" in calamine lotion. Calamine lotion doesn't contain bentonite.
It's possible you are thinking of a product that combines the soothing properties of both bentonite clay and calamine. Some skincare products may use a combination of these ingredients for their calming and anti-inflammatory effects.
If you are curious about a specific product, please provide more information.
