Even after taking every precautionary measure listed to stop glycerin rivers from occurring I still get bars of soap full of them. My recipe is 40%olive oil 25%coconut oil 25%palm oil 5%sweet almond oil 5%castor oil I use a 10 to 15 percent water discount. I have used both heat transfer method and by having my mixed at around 110degrees before combining. Then after pouring in my mold I put in my refrigerator to make sure it doesn't get to hot. Nothing helps. Any idea why?
