How to make soap

Soap can be made from waste fat. Secure some waste fats and melt in a dish. Strain the fat by several layers of cloth. Weigh the fat and then weigh out about one third as much for profit lye (sodium hydroxide). Dissolve the lye in water. Heat the fat in an iron kettle or dish. When it is melted, pour the lye solution in slowly and stir continuously. Stay the flame low to avoid boiling over. Let the fat and lye boil for 30 minutes with recurrent stirring. After boiling add common salt-about twice the weight of lye used. Stir well. When this mixture has cooled the soap will appear as a layer at the top.
