Soaps with clay

What are some great soaps that contain clay as an ingredient?

Honeybee Spas and The Gentlemen's Quarter are two that come to mind.

SCS soaps have clay, and they do have some nice slip to them!

Quite a few of Olivia's soaps have them: http://www.olivia-seife.de/menshaving.htm

Check if there are any local soap makers in your area. If they have the supplies or access to them, they can make any kind of soap for any purpose....especially for shaving since this is a shaving site.
