Hot process soap making is a method where oils and lye are combined and heated to create soap. This technique accelerates the saponification process, allowing the soap to be ready for use much faster than cold process methods. The mixture is typically cooked in a slow cooker or double boiler, which helps to ensure that the lye is fully reacted with the oils. Once the soap reaches a thick, pudding-like consistency, it can be poured into molds. After cooling, the soap can be cut and used immediately, making hot process soap making a popular choice for those who want quick results. This method also allows for the addition of fragrances and colors during the cooking process.
