Tallow Saponification Stoichiometry Guide

Its printed title: The Stoichiometry and Synthesis of Potassium Tallowate: A Chemical Engineering Guide to Antibacterial Wood Ash Soap

Potassium soap made from beef tallow and wood-ash lye, worked out step by step for kitchen hygiene. It tables the fatty acids of tallow, explains saponification values, the use of calcium to turn the potash into caustic lye, and the testing of lye by egg and by titration, then follows the reaction, hard water and the soap's action on germs. The opening history repeats doc 76 nearly word for word, several chemical formulas dropped out, and the antibacterial claim is the document's own.
