To make glycerin soap, you need to visit your local craft store and purchase blocks of white or clear glycerin. You will also need to purchase cosmetic grade fragrance and color. You simply melt the glycerin in a glass container in your microware (don’t let it boil). Then you add the fragrance and color and pour it into a mold. You can use small, flexible pieces of plasticware as molds. Let the mold cool for at least 2 hours before you unmold the soap.
