Excerpt from Manual of Mining Tools: Comprising Observations on the Materials From and Processes by Which They Are Manufactured; Their Special Uses, Applications, Qualities, and Efficiency
Chemical analyses have proved that, almost invariably, red-short iron contains in some form sulphur, and that cold-short iron contains phos phorus; hence, when iron is tender and weak at a red heat, or when cold, the cause is attributed to sulphur in the former case, and to phosphorus in the latter. Iron derived from the ores of some districts is noted for red-shortness; that from the ores of other districts for cold-shortness. Some ores give iron which is both red-short and cold-short. Naturally, those ores which are freest from sulphur, phosphorus, and other deleterious elements, yield pi g-iron most suitable for the pro duction of -best bar-iron. The smelter reduces and separates metallic iron from the ores by slaggz'ng or scorifying the accompanying earths, metals, &c and during this operation it is his duty to prevent, as far as possible, the com bination of any injurious element with the iron obtained. This is partially, or wholly, accom plished by introducing to the smelting furnace.
