I love salt bars, but as cmzaha said, they need a longer cure. This post shows the difference.UPDATE: After letting my bars cure, I've been using one of them for the past couple of weeks. Tbh, I'm not thrilled about how they turned out. They're too hard and I can't feel the salt when I use it. I did some research and it turns out that I should be doing 20% superfat, where as my original recipe uses a 5% sf. I'll try it again at 121g lye and let you know how it goes.
