Today I made a batch of soap. I added the lye when the oils where at 120 degrees. As soon as I added the lye the soap gelled and I could hardly get the colorant and fragrance mixed in the batch. I decided to put the batch in the loaf mold. As I was spooning the soap in the mold I noticed that the lye water was separating from the soap. What caused this? I am at a loss.
