Re: lye question When you run your recipe through a lye calculator (read the Sticky thread, "Soap/Lye Calculators; A guide" if you haven't already), it will tell you the amount of lye to use and the amount of water to use. Using an accurate scale, measure the weight of the water (i.e., 32oz of water means the water weighs 32 ounces, not that you've filled it up to the 32oz line.) Put on your goggles and your rubber gloves. Put the lye into a plastic pitcher that you're not going to use for anything else. POUR THE WATER INTO THE LYE! Do not pour the lye into the water. It's best to mix the lye and the water outside, if possible, or in front of an open window with a fan to blow the fumes outside.
