The International Exhibition: group of objects in steel exhibited by Mr. Krupp, of Essen, Prussia, 1862. '...it is only recently that the great stride has been made which causes [Krupp's] to outstrip all competitors...Their great steam-hammer strikes with a force of fifty tons; the anvil for this gigantic hammer to work upon rests on castings weighing three million pounds; and ingots of steel are produced weighing thirty tons. Among the most important of the different objects...was a cylindrical ingot of cast steel...This ingot was broken in the middle in the cold state...The two fractures thus produced are for the purpose of demonstrating that the manufacture of even the largest pieces is perfect, and that the ingots in the rough state are quite free from...faults...Two pieces of cast steel were exhibited that were exceedingly interesting, for they represented the manner of manufacturing one of the most important products of these works - cast-steel railway-tyres without a weld...For marine purposes there was a double-crank propeller-shaft for a Transatlantic screw-steamer...Amongst the artillery two guns were exhibited in the finished state...[Krupp's] are now able to execute bored barrels on a large scale, specially for military purposes'. From "Illustrated London News", 1862.
