This 12" pipe mold held about 40 oz. of soap base. Because you don't know exactly how much space the loofah is going to take up, I usually melt a little more than I have to - just to be safe.
Put the soap base in the microwave and melt it at 1-2 minute intervals. Heat it, stir. Heat it, stir, until it is hot (about 180 degrees) and completely melted.
