Just wanted to give an update on these. When I made these, I used a silicone mold and it made six bars. I have given away two of those. Would you believe we are just now using up the last bar? Wow, those suckers last forever (Of course, I expected them to last a little longer since they are facial bars, but still four bars lasting for a little over a year is awesome!) It makes me want to change all my soap to salt bars because they last so long!
