When first starting out, 110F is a fairly good temperature. Start with small batch, uncolored or single color, and see how the batter reacts.
My recipe is 60% Hard Oils and I typically soap at around 80F-85F…gives me plenty of time to do my Drop/Chopstick Swirl. If I’m doing a single-color soap, I’ll soap a bit warmer ad give the Stick Blender and extra whiz or two.
When you make up your Oils and Lye Solution is completely up to you. When I first started, made everything up at the time I was making soap and of course, had to wait for the Lye to cool down. I eventually started making my Lye Solution the night before, but you want to make sure you cover it. Then I started making large batches of my soap and then sub-dividing for various soaps. I once make seven soaps at one time and I said I would never do that again.
These days I Master Batch my Oils/Butter…640 oz in a 5-gallon bucket and make up a couple of ready-to-use Lye Solution. I could fit a 1000 oz of Oils/Butter, but I don’t have a dolly for my bucket. Anyhoo…when I’m ready to make soap, I have a worksheet with all my molds on it which tells me how much Oils/Butters, Lye Solution and FO I need. After using a commercial paint stirrer on the end of a drill, I tare my container and scoop out however much oil I need and pop it in the microwave. I then measure out my Lye Solution and FO, do the do-wah-ditty, clean out my container and on to the next batch. As along as you keeps your lids on tight (make sure you wipe off the mouth our your Lye Solution jug and rinse the cap…I’ve kept MB’d stuff for a good six months.
