You can make your own lye soap at home; it’s really not hard to do. Soap is what you get, when you combine fat with some sort of caustic agent, using water as your catalyst. You won’t need anything exotic to make your own soap; most of the ingredients you need may be as close as your grocery store. The first step is to dissolve the lye in the water. Never pour the water into the lye;candle making ideas instead, pour the lye into the water. If half your water is ice, that’s even better. Stir the lye to dissolve it; and as you stir, watch for the reaction that will take place. The lye can every start the water boiling, and if this happens, stop stirring until the bubbling stops.
