Soooo, here's my Raglan Sand and Surf soap - made from real Raglan seawater and black sand. A little more rustic than I had in my mind's eye before I made them - but it seized up really quick from the EOs I used. And actually the black sand was even LESS gritty than the pumice I used in my previous soap. It was very, very fine, almost like rice flour. I certainly won't be using it again, not very scrubby at all!
