Excerpt from The Methods of the Chemists of the United States Steel Corporation for the Sampling and Analysis of Fluxes, Cinders, and Refractories

In metallurgical practice, it is desirable that the methods of analysis for all materials, including fluxes, cinders, and refractories, should be rapid and at the same time reasonably accurate. Since the metallurgist must rely largely upon the results of chemical analysis in order to select and dispose of his fluxes and refractories to best advantage, and since the analysis of cinders, or slags. Are important factors in controlling metallurgical processes, time is seldom available to the chemist for the painstaking care required to perform an accurate complete analysis. Again, emergencies frequently arise in which the prompt revelation, by the chemist, of the character of such materials as blast furnace slags, which are produced in large quantities and of varying composition, is of the greatest importance. Obviously, such a revelation is possible only when rapid and accurate methods for conducting the analyses are pursued.

To meet these needs and to establish standard methods for the sampling and analysis of these materials, a committee of chemists of the United States Steel Corporation was appointed to select and compile such methods. In performance of its work, this committee made a thorough canvass of the chemists of the Corporation to obtain all methods in vogue at the various laboratories. These methods were classified and critically examined and those which met with the approval of the committee are presented in this pamphlet on the sampling and analysis of fluxes, cinders, and refractories.
