Hard Soap (Washing)
Instructions
Six pounds of washing soda and three of unslaked lime. Pour on four gallons of boiling water, let it stand until perfectly clear, then drain off, and put in six pounds of clean fat. Boil it until it begins to harden, about two hours, stirring most of the time. While boiling, thin it with two gallons of cold water, which you have previously poured on the alkaline mixture, after draining off the four gallons. This must be settled clear before it is drawn off. Add it when there is danger of boiling over. Try the thickness by cooling a little on a plate. Put in a handful of salt just before taking from the fire. Wet a tub to prevent sticking; turn in the soap and let it stand until solid. Cut into bars, put on a board and let it dry. This makes about forty pounds of soap. It can be flavored just as you turn it out.
