I just made a salt bar using the recipe out of Faiola's book. I expected to wait a few weeks to un-mold but low and behold I was able to un-mold after 6-7 hours. I haven't un-molded the loaf but the bonus little silicon mat bars popped right out. Everything seems OK, just not what I expected. I did use a Sandalwood FO that I had not used before. Should I be concerned?
