Fine grains of soap that can be used to make soap yourself. Put 100 g of soap in a heat-resistant bag, and pour 15 cc of rather hot water over the soap. Knead well the soap over the bag into a single block. Take the soap out of the bag, make it into a ball shape, and knead it well like working clay. Form the soap, and place and dry it in a well-ventilated place not exposed to direct sunlight for about ten days. Your original soap will be finished. *When you add an essential oil to give the soap a scent, reduce the amount of hot water by the amount of the essential oil to be added.
