I had a 6.5 hour sidetrack reading this thread about Andalusian soap. It's a 69 page, 3 year old thread and I figure I'll start a new one to hopefully not confuse things. Main summary: a member found a recipe that combats "castille slime" by using an extremely low super fat, -40%. It looks like several posts were removed at some point because some of the post numbers mentioned in the thread don't quite match up. I haven't made soap all month and if I can get myself together to clean my mold I'd like to try this superlye recipe but need to "think out loud" to make sure I absorbed everything right (I have 9 pages of notes, even if they were on a mini legal pad) I plan to use DeeAnna's first recipe from post 40: 1000g OO 195g NaOH 1195g water, split Confirming method: Make a 50% lye solution then mix it with oils after it clears but before it cools. Hand stir to bring to trace. Slowly mix in the remainder of the water until everything looks like pudding. Pour. (Cut after 24 hours, except I want to use an individual cavity mold) Random advice: Use a short, wide bowl No embeds Expect the lye concentration to mess with colorants (at least those that morph) Don't use technology (per post 461) There is a possibility that I'll see some sort of riding before everything comes together Some highlights from the thread if you are interested but don't have 6 hours to spare: Some pics of the process - post 78 We had a member from Andulasia who doesn't seem to be active any more - post 301 A summary to date from DeeAnna - post 405 Some musings about superlye combating DOS - post 406 The technology comment - post 461 Another explanation of trace stages - post 468 An analysis of use as a laundry soap - post 473 DeeAnna discussing the experiment with Kevin Dunn - post 481 Comparison of other negative superfats - posts 596, 611 Analysis after cure - posts 612, 643 Does all of this seem right/make sense? I kind of want to jump in but that -40 is a very scary number.
