Excerpt from A Manual of Practical Assaying Fire-assay determinations involve the separation of the metal sought from the other constituents of the ore by the aid of heat and suitable fluxes, and its estimation by weighing in a state of purity. For example, if the object is the determina tion of lead in an ore, the ore is mixed in a crucible with suit able fluxes and fused. The lead is reduced to the metallic state, in which condition it is readily detached from the slag for weighing.

Excerpt from Manual of Practical Assaying: Intended for the Use of Metallurgists, Captains of Mines, and Assayers in General, With a Copious Table, for the Purpose of Ascertaining in Assays of Gold and Silver the Precise Amount, in Ounces, Pennyweights, and Grains, of Noble Metal Contained in One These considerations, coupled with the paucity of any knowledge of assaying, excepting that confined to a very limited number of persons, induced the author of the following pages to turn a considerable amount of his attention to this subject, more especially as much difficulty was experienced in not having a suitable text-book for the use of his pupils. A portion of the following pages was drawn up as a Manual for such a purpose; but on consideration, it was thought the extension of such a work was so much needed, that it was determined to alter the original plan as far as was consistent with the complete carrying out the object in view, viz.: the production of a Manual embodying information in every branch. Of assaying, either by the wet or the dry processes. The following is a sketch of the manner in which this is accomplished: the author having followed the excellent arrangement of Berthier as closely as possible, from whose work also much matter that suited these pages, and which it would have been useless to re write, has been inserted. Firstly, the Mechanical and Chemical Operations of Assaying are treated in full, inclusive of a description of the apparatus required.
