How to Make Old Fashioned Lye Soap

Allow the lye mixture to stay under a vent and cool down while you prepare the fats/oils. Measure the fats/oils by weight and then place in a crock pot to melt on low heat. Once melted, add the lye/liquid mixture to the oils in the crock pot and stir. (Note: Any equipment the lye touches needs to be neutralized in a mixture of white vinegar, soap, and water.)
