I made a batch of soap last night that would not come to trace. The only thing different from the last 2 batches I made was that I noticed my lye was clumpy, like moisture had gotten to it. (I live in very humid Iowa) Could that have caused my problem? Can I still use that container of lye? In the end I mixed up a little more lye and water, and it did finally come to a very thin trace, and the soap is looking good this morning.
