This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1851 edition. Excerpt: ... Pure hardened lead, for bearings, types, &c. Mixed vitriol. The sparry iron ore is used for the manufacture of pig iron, and changes in roasting into magnetic ironstone, discernible by the crystals. The manufacture of iron into bars, by means of gas, is but in its infancy; but the iron produced in this manner is considered to be preferable to that produced by means of charcoal, and to the puddled iron in bars made by pit-coal. The lignites of Germany have not been found favourable to the production of good iron; the principle has, therefore, been introduced of distilling the fuel in close vessels, and using the resulting gases in a state of combustion in the furnace as the source of heat to melt the iron. The results, as far as the experiment has yet been tried, are very satisfactory, and the use of gases there is rapidly extending in the iron districts of the Continent. The relative values of the iron-producing States of Europe may be inferred from the following return obtained in 1845: --Tom.
