I have only made two batches of soap in my life. The second batch was a shampoo bar, and I was a tad bitsy short on the lye. I ran out and instead of aborting the project, I crossed my fingers and hoped for the best. The bars still cut, but are a bit soft and seem somewhat greasy. Does the greasiness mean it didn't saponify fully? It does lather a little when I used one of the bars. We'll see how my hair feels/looks when it dries. What are the odds I could let the bars cure a little longer and they'd harden up? I wouldn't even mind if they are just soft. I have looked into rebatching (?) it. The questions are, what recipe did I use (I don't know which one it was anymore!), and how short was I on lye? If I had to guess, it seems I remember saying what a shame it is that I was a mere 1 oz short. Should I just melt it down and add an ounce of lye to it? Would this added lye have to be mixed into a bit of water? How much? Is it just this easy?
