If you use silicone molds, it also takes longer for the soap before it's ready to unmold. 2 days is definitely average, but 3-4 is more likely for me.

My experience is pretty much the same depending on the recipe. For ungelled 100% olive oil, they are consistently finished at about the 60 hour mark in a dry room @ 23 degrees C. Up to about 55 hours, they're still zappy and very soft. Then suddenly over the next 5 hours the change is amazing. They become rock hard, and I think if it ever stuck to the silicone I'd end up ripping the silicone before breaking off any soap! Keep in mind that I do use a water discount for this soap (40% lye to water).
What I find interesting is that nearly nothing happens for 55 hours, then boom - 5 hours later, done. My hypothesis is that olive oil when used alone has a very simple fatty acid profile, the majority being only 2 of them, and that these acids begin and end saponification at similar rates. In a more "balanced" recipe containing a complex mix of fatty acids, they all saponify at different rates and thus the soap reaches complete saponification more gradually and at a more even rate. Maybe? Hahaha!
The sodium acetate does speed the initial hardening some. I typically unmold within 24 hours even less if I am using a recipe with a high percentage of "hard" oils ( like lard).Thank you so much for bringing this up.. I went through the threads and loved the information. This form never fails to amaze me with the information.. you guys are amazing. One more question, when you use half vinegar, when can we remove from the mould and cut the soap as I read that the soap will get hard fast and might be difficult to cut.
That does make sense. I want to make a castille soap... but the year long cure kinda keeps me thinking.... as I am just starting out and wanna experience my soaps asap..... beginner's curiosity I guess....
