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.
