Just came across this article: http://www.soapmakingforum.com/History-Soap.html
I've read elsewhere that it was Sopa (spell?) Hill is where the sacrifices took place. I've also heard it was human sacrifices. But that might just be from Fight Club.
I also claim I use a soap making method that's nearly 5,000 years old because of what I've read.
Just trying to clear some things up and understand the history of this awesome stuff we make.
