Don't put it on your face!

A silly lady, yesterday, in Pugsley, Arizona.

My brother has a friend who is in import/export mainly Spain to UK. She has been involved in importing a clay mudpack thing, and wanted to try some of the clay we use at the factory.
Not a good idea. We add Barium Carbonate to it (to suppress the mineral salts that work their way to the surface during drying and discolour the tiles during firing) as well as Ammonia to prevent a kind of white streaking that can occur on firing.

I found this recommendation of a mudpack on the web -
You really feel this face pack working, drawing out the impurities, leaving your skin feeling nice and smooth and, above all, oil free!
Now how does he know it was impurities being drawn out? Maybe it's the good stuff. How the hell does the mud know what's good and what's bad for your skin?
It's like all those magnet therapies - magnet bracelets etc. How come the magnets only work in a positive way?

But the worst part of the above quote was that it came from a web site of beauty products for MEN! Mankind Ultimate Grooming
Now in the name of all that is holy, what kind of man puts a mud pack on his face and then writes a glowing testimonial about it?
Everytime I use it i get comments about how good my skin looks. I only use a little, once a week around the oily parts of my skin (chin & T zone).

What in blue-rinced Hades is a T zone?
