PREFACE TO THE FIFTH EDITION The fifth edition of Metallurgical Analysis has been made necessary by the rapid development of control and testing methods in the industrial, and especially the metallurgical, world in the past seven years. The author has been actively engaged during this period in metallurgical testing both as a teacher and as a consulting metallurgist and has been forced to recognize the desirability of a complete revision.
In this revision the old material has been largely rewritten. The chapters on coal calorimetry, gas calorimetry, fire assaying and electrometric titration are entirely new. The chapters on water analysis, analysis of alloy steels and gas analysis have been almost entirely rewritten. Nearly all of the methods described in these and other chapters have been used many times in the author's private laboratory by experienced analysts and in the student laboratories as well. The author feels, therefore, a good deal of confidence in the practical usefulness of this new edition.
The scope of these methods has been enlarged to include insofar as possible all of the chemical analyses which the metallurgical chemist is likely to require except those of paint. The earlier editions of this book have been widely used in the works' laboratories and in college metallurgical laboratories where a bulky text is not altogether desirable. For this reason explanatory matter concerning the fundamental principles of analytical chemistry, use and care of balances, calibration of instruments and the principles and methods of stoichiometry is not included in the text. A statement of a few of the fundamental principles is, however, given on page xii for convenience reference.
The author wishes to express his appreciation of the help received from his brother, F. M. Demorest, through whose careful and accurate analytical work so many of the methods described in this book have been tested.
