I got "Soap and Other Obsessions" yesterday, and I'm on the goat milk chapter. Has anyone tested this? I believe her, but i just can't see how it's possible. Stir the oils as you slowly add the milk/lye solution. From here on it is just the same as you would do any of your soap recipes. Only difference is you put it in the refrigerator so that it will not gel. If it gels, it turns darker. If you've used a fragrance oil that turns dark, there is no reason to put it in the refrigerator. Leave in the refrigerator for 24-36 hours. 36 hours gives a little harder bar as the refrigerator takes a little of the moisture out. There will be no active lye after 48 hours. Now, does that mean that it's usable after 48 hours??
