"Frémy’s first project was to continue Pelouze’s studies of iron oxides, and he expanded them to include oxides of chromium, tin, and antimony that form salts with alkalies in the same way as manganese. In 1835 he published a memoir in the Annales de chimie on the splitting of fats by sulfuric acid, a process that was adopted by French industry. From then on, Frémy pursued scientific investigations as professor and industrial work as consultant (later as administrator of the Compagnie de Saint-Gobin). He proposed improvements in the chamber process for making sulfuric acid (low temperature and ample air and water), and he introduced the residue from burning pyrites as the raw material for iron production. From research on the setting of hydraulic cement, Frémy proceeded to the synthesis of rubies by heating alumina with potassium chromate and barium fluoride."(DSB).
