To Make Soap 5 pounds lukewarm melted fat 1 can (pound) lye 1 quart cold water 3 teaspoons borax 1 teaspoon salt 2 tablespoons sugar 1/2 cup cold water 1/4 cup ammonia Fats that are not fit for food may be made into soap. Melt fat and strain through cheesecloth. Dissolve the lye in cold water and let stand until cool, then add fat slowly, stirring constantly. Mix the other ingredients together and add to the first mixture. Stir the whole until thick and light colored. Pour into a pan lined with cloth. Mark into pieces of desired size before soap becomes hard. When hard break pieces apart and pile in such a way that soap may dry out well.
