I make soap in big quantities- 12lbs of oil/batch. I master batch my lye at a light concentration (33% lye) to give me time to work it, but my last two batches stiffened really thick really quickly, the last almost immediately. I used the same lye batch with both. With the first one, after I cut it and let it sit for a couple days I tongue tested it for alkali and got a neutral taste, so I don't think I have any free-floating lye there. The second, after pulling it out of the oven next day (I oven process them all), I noticed beads of what I suspected to be either water or fragrance oil at the top. However, upon investigation I find that these beads are definitely lye (no smell, zapped my tongue pretty good with the most miniscule dap of the residuals on my finger). I fist saw these beads before I put it in the oven when I banged the mold on the floor to try to get out air bubbles from the pretty stiff soap in there, and the beads came to the top. Ultimately, my question is, is there any way to save this batch through hot processing them, which I've never done?
From an outside perspective, I'd say I must have screwed up my measurements and put too much lye in the batch, probably by mixing it to heavily with lye or too lightly with water. I'd like to say there's no way I'd do this, but... Maybe? Or, maybe it saponified unevenly since it traced so quickly, but this seems unlikely since it did trace so quickly with such a light lye concentration. If there is extra lye, then even in hot process I should have to add oil, to get it to saponify, right? How would I determine how much oil to add? Is this batch hopeless?
I'm throwing out the master batched lye either way since these results make me suspicious of it. If anyone's had this experience or has some advice on how this batch might be saved (or is definitely hopeless) I'd really appreciate it.
Attached is my recipe for the bad batch.
