I remember reading material that you've mentioned. All this is so interesting to me and I could spend (have spent) hours and hours reading just for the sake of soaking up all that I can--for knowledge sake. It's time-consuming and labor-intensive so, yes, one needs to understand all the ins and outs before delving into making pioneer-style soap. You bring up really good points......as usual. I hope I live long enough to become as knowledgable as you .
