Brunet, 1722. First edition of the first comprehensive book devoted to the manufacture of iron and steel; it "laid the foundations of the steel industry in France."-Partington, III, p. 64. RÃ©aumur was the first to recognize that steel was actually impure iron and set up the first scale of seven types of fracture of iron and steel. The fine plates are valuable for illustrating the contemporary apparatus and methods of converting iron into steel. For a detailed account of this book, see D.S.B., XI, pp. 328-30. A fine and handsome copy. Ex Bibliotheca Mechanica. ? Roberts & Trent, Bibliotheca Mechanica, pp. 273-74-"RÃ©aumur's most original contribution to industrial technologyâ¦Part one, containing twelve memoirs, deals with the production of steel from the construction of the furnaces, through the tempering process and the apparatus used to determine the hardness of the finished product. The second part, in six memoirs, describes the various kinds of cast iron, and of casting methods, moulds, additives, and furnaces. As well, it explains a process for producing cast iron using red oxide of iron, which was unique to the 19th century.".
