Human: I've been trying to learn how to make my own soap. What are the different types of soap I can make? Assistant: 
There are many different types of soap you can make, depending on what ingredients you have available and your desired outcome. Some popular options include cold-process soaps, melt-and-pour soaps, castile soaps, glycerin soaps, and herbal soaps. Cold-process soaps involve mixing lye with fats and oils, then allowing it to sit for several days or weeks before using. Melt-and-pour soaps are made by melting solid bars of soap in a container, usually a microwave-safe bowl or jar, and adding essential oils or other additives. Castile soaps are typically made from olive oil and lye, and they tend to be mild and creamy. Glycerin soaps are made from vegetable oils, glycerin, and lye, and they're often used as moisturizers. Herbal soaps are made with natural herbs and essential oils, and they can be soothing and relaxing.
