Well, I googled it and the only real bit of info I could find was here:
http://www.jstor.org/pss/2834912
It seems like it could be the reason they don't work in salt bars for many people is that they may lower the pH of the soap so much that it can't stick together- similar to the sludge you get if you try to add citric acid.
Just wondering, anyone out there who had a failed batch using Dead sea Salts still have some you can reconstitute and check to see if they're acidic? Might be interesting to see.
Also, has anyone actually had success making a batch with dead sea salts? Maybe it repends on the source how acidic it is?
