Steel and iron have long been manufactured at Ulverstone, and the quality or fitness of the ore for the purpose is attributed to the presence of manganese in the ore, which since the establishment of railways has come into general use. In Mr. Reynolds’s time we imported large quantities of iron and steel; and ignorant of what constituted the difference between our own and that of foreign markets, had with some humiliation to confess our dependence. In no case had a uniform quality of bar-iron with the superior marks of Sweden and Russia been produced. A great variety of processes had been tried, and makers were not wanting who made laudable efforts for the accomplishment of the object, feeling that in so doing they devoted their time to the service of their country, and that in a national as well as a commercial point of view no experiments were fraught with more important consequences. Mr. Reynolds thought he saw the solution of the problem how to produce metal equal to that made from the magnetic and richer ores of the Swedish and Siberian mines, when Bergman published his analysis of Swedish iron, showing the large percentage of manganese it contained. The analysis showed the following results: CAST IRON. Parts. Plumbago 2.20 Manganese 15.25 Silicious Earth 2.25 Iron 80.30 100 STEEL. Plumbago .50 Manganese 15.25 Silicious Earth .60 Iron 83.65 100 BAR-IRON. Plumbago .50 Manganese 15.25 Silicious Earth 1.75 Iron 84.78 100 In order to effect a combination corresponding with this analysis of the French chemist he introduced manganese into the refinery during the re-smelting process, and succeeded in producing bar-iron capable of conversion into steel of better quality than had previously been made from coke-iron. From subsequent experiments the per-centage introduced of metallic manganese could be traced into bar-iron, the inference being that the purpose served was the additional supply of oxygen it gave to burn out the impurities—a result the Bessemer process has since attained in another way. When it is remembered that the end to be attained in these processes is to consume the impurities of the metal, and that those impurities are of such a nature as to unite with oxygen at a high temperature and form separate compounds, also that this boiling and bubbling up of the liquid metal was carefully watched and tended formerly, one can understand how near the iron-kings of a past age were to the Bessemer discovery of the present.
