Last weekend I made 2 batches of soap that I have made before. I usually put my lye water in the garage over night and soap at room temperature and have no problems. Well, we had a lot colder weather here in AZ than normal and I didn't think about the fact the garage was a lot colder. My lye did not freeze but it was very cool. Anyways, my soap traced so fast, I didn't even have enough time to thoroughly add much color. I had to scoop the soap into the mold. I ended up tossing the soap in the trash because I hated it, what a waste of oils! I would wait until the lye water warms up to room temperature before using.
