I made my Utah Salt Flats soap last night, rather late, and was going to stay awake long enough to cut before it got too hard. But when the alarm went off at 6 am, I still hadn't cut them. I cut them right away and they were still a bit warm, but hard enough that I got a bit of crumbliness around the cut edges. Since I expected that, I cut the mini-slab into 4 large rectangular bars instead of 6 square bars to minimize the opportunities for crumbling. It wasn't too bad. And it was only a test anyway.
When I get back home, I'll take some photos since I haven't done so yet. I am considering stopping off at the salt flats on my way through Salt Lake City again tomorrow or a little beyond on the edge of the Great Salt Lake and gather more Utah salt.
I liked the feel of the salt I used from the Salt Flats, but of course, I have yet to get a feel for it in soap. BTW, I weighed the salt, then like a ninny, did not write down the exact weight, so don't have a specific percentage, which is a bit of a bummer.
I also dropped off a bunch more soaps for my son, right before I left for my trip home. I told him to share with his friends as he wishes.
