I do OHP and my soap is always fluid enough to pour (no water discount and add sugar and silk to lye water; sometimes SL at end of cook). I love adding salt to my bars, but I find if I keep it at about 25% of oil weight, it doesn't compromise the fluidity; otherwise, it can thicken it up too much and make it unmanageable. The main reason I love adding salt is it makes for such a hard bar, which is sometimes a problem with HP soaps. I use a 50% coconut recipe with butters totalling 10%, castor oil at 10%, and the rest palm or lard, and rice bran oil. Makes a very white soap (if the fo doesn't discolor) and sets off a swirl nicely. The sugar and castor oil help with lather, so I'm pleased with the bubbles I get. In my log mold, I keep an eye on it and turn it out after 2-3 hours and am able to slice it without crumbling.
