Something new to me. Thought about trying for years but never got around to it but I started playing around over Christmas. Anyway here is the lye/oil soap that I made today... 10.5 ounce of coconut oil, soybean oil (vegetable), and shea butter. You need to melt the solid fats. I do it on the stove top over low heat. Next the lye/water mix. 119 grams of lye with 8 ounces of water. The lye goes in to the water not the other way. If you add water to lye you are going to have a bit of excitement going on. Add to the water and stir constantly. The lye solution will heat up to anywhere between 170 and 190 degrees. Do it over a good exhaust fan or outside. Not a pleasant thing to breathe in. You need to cool both the oil and the lye mixture down to around 100 degrees. It has to be between 90 and 110 to work correctly. I submerge the pans in an ice bath and stir until the temp drops. It doesn't really matter which you do first but they both have to be at a similar temp before you mix them. Once they are both cooled use a submersion blender in the oil and slowly add the lye solution. Add in fragrance once it starts to come together a bit. Blend until you get a thick pudding like consistency. Dish into a mold. Smooth it out and throw it in the oven at 150 for three hours. Shut off the oven and let it cool over night. It will be ready to slice in the morning. It is best to let it dry out on a rack after it is slice for a few days. It will harden up and last longer that way. Thanks Mountainman for helping out with this one.
