I use bentonite clay in my Charcoal/Clay soaps. I swirl them black & white, with the bentonite clay in the white part of the swirl, of course. I love the Charcoal/Clay soap as a facial soap and so do my customers.
What a great idea! I never even thought of this, and I have some laying around in my hall closet. That's why I love this board, you guys are sooooo full of fresh ideas! Thanks!
