Failed Batches
Hmmm...I'm sorry about that. Don't give up!
A few things: I've been soaping, since October of last year, so I don't have many years under my belt, but I've only had two failed batches of soap — God has been VERY good to me, and I READ A LOT.
I've soaped quite a few different oil combos, in my short time as a soapmaker. Both failures (seizing and separation) had to do with FOs that were soaped too hot, for my particular recipe. Now, I do RTCP (heat transfer method) and I've hand stirred the majority of my batches, and recently returned to handstirring, because I prefer it to stickblending. My recipes trace pretty quick (for handstirring), because of the combo of oils I use, and the temp. I don't do castille/bastille soaps, nor do I use very high amounts of olive oil. My lye water is usually moderately hot, with my oils at room temperature.
I handstir with a wire whisk, which is WAY better for gettin' things going in the soap pot, than a plain ole' spoon — equipment is often as important as technique.
So, my advice is: Watch your FOs — especially florals and spice scents. Soap cool, and add at very light trace. Sometimes a SB can beat a tantrum causing FO into submission.
