How do i figure how much lye you use if you want to use milk in some of your cold process soap? On the bramble lye calculater i don't see a place to say that your using milk just oils. How do i figure it out? I am also still confused about in the lye calculater where it says superfatting percentage. What do i put there? Can someone help clear up that for me and what is considered a godd superfat amount? I have so far made 6 different batches of soap so i am still a beginner but trying hard to learn. Thanks for all your input and patience for a beginner like me!!!!
