Hi everyone. I've been soaping for a little over 6 months. Started real slow with an olive oil cp Soap recipe I learned from the how to book that I started with. Became so familiar I decided to branch out into a palm oil recipe I found online. Here's my question. When I made my first 4 lb batch of the palm oil soap, everything seemed to be going just as expected. It wasn't until I had them cut up and drying on my rack when I noticed small salt like crystals forming on the cut sides of some of the bars. Then to add on to my first bizarre soaping moment, the little scraps I tossed into the olive oil scraps from previous batches caused (I believe) a glycerin sweat reaction, but only when left touching palm oil to olive oil. I was able to remove easily with rubbing or wiping with a damp cloth. I'm not too alarmed just curious, how common is this, and can the crystals be prevented?
