I have a major problem! I'm new to soaping, only have about 18 batches of soap so far. I'm letting my soaps cure for 6 weeks and using the Phenolphthalein for the lye test. Many of my soaps are not passing the test!! I've used lye calculators and there's plenty enough distilled water.... why is this happening? Everything is mixed well. In some of my soaps it is just the smaller sample size bars in which I used mineral oil as a "release" oil in the plastic molds, the larger loaf bars are fine. Others were done in the oval silicone molds and are quite caustic. Some of the caustic ones have an "ash" on them as well. May I inject here that many of soaps are fine and are passing the lye test. I don't seem to be doing anything different with these caustic ones except for the oil mixtures but I've checked the lye calculator.... so frustrating!! Anyone have any ideas as to what I'm doing wrong? All my soaps are CP. I think I'm going to cry :-( but in the mean time I'll enjoy my wonderful soaps that turned out fine!
