Cold Process Soap Making is a method of creating soap by mixing oils and fats with a lye solution. This process allows for the natural saponification reaction to occur, where the lye reacts with the oils to produce soap. The mixture is poured into molds and left to cure for several weeks, allowing it to harden and develop its final properties. During the cold process, various ingredients like essential oils, colorants, and additives can be included to enhance the soap's fragrance and appearance. This technique is popular among artisans because it allows for creativity and customization in soap design.
