The Hot-Process Method

The hot-process method of soapmaking is similar to the cold-process method in that you start from scratch, which allows you to choose from a wide range of ingredients, and you use lye. However, as the name implies, this method involves the application of heat. With the hot-process method, you either cook your soap on the stove in a large stainless-steel pot or bake it in the oven (keeping a close eye on it at all times) or use a slow cooker. Hot-process soap mold can be used immediately; however, without the 4- to 6-week curing and drying time used in the cold-process method, the bars are softer and do not last as long in the shower
