Sounds like the bath drew lymphatic acids to the surface of your skin... this is what is intended.

Some baths can be more potent than the next, try less clay next time... or, alternatively, you can take a cold shower after the bath to help "cool" or "slow" down the reaction.

The stronger the reaction, the longer it may take in the cold shower to bring it back to normal.

You can get a "visual" of what is happening by making a bath with Epsom Salts (1 - 2 cups), H2O2 (Hydrogen-Peroxid) (1 pint to 2 quarts 3%), a half gallon of lime water (tablespoonful of pickling lime in a gallon of distilled water), and some baking soda (.5 to 1 cup)...

I use the hottest water I can stand...

You sit in the bath and it may start to fizz if you have the ingredients mixed right... this is the acids in your skin reacting with the minerals in the bath. The water may start out very clear and turn a murky gray if the solution pulls that much acid/junk out of your lymph through your skin.

You may sweat profusely as well... so have lots to drink with you.

NOTE: The stronger the bath, the more apt you are to have negative reactions during or after, so use common sense and caution; start with smaller amounts of the ingredients first and work up to larger amounts till you find "your" sweet spot... in addition, a strong bath can cause you to become severely dehydrated so drink as much water as you may need... I prefer a good mineral water with lemon or lime squeezed into it... and again, cold shower to cool down back to center and slow/stop the reaction.

Be careful to protect metal plating... if you do not believe these few minerals (calcium, sulfur, magnesium, sodium) can "chelate" metals... make a mix and stick some plated metal in there and see what happens.
