Metallography and Microstructure of Aluminum and Alloys

You must use a highly alkaline solution, such as sodium hydroxide, in order to transform oils into soap. In the presence of heat and water, the fatty acids and glycerol in oils bond with the sodium and hydroxide portions of lye to form brand new substances — soap, plus glycerin — which are great for your skin. No lye remains in the final soap.
