Zn Fe Pb Reduction of the metal oxides in a blast furnace. Carbon is used as the reducing agent. It is often in the form of coke (made from coal). Although this uses a lot of energy‚ this is cheaper than using electricity. Hydrogen Copper Silver Gold Cu Ag Au These metals occur “native” (as uncombined elements) in the Earth’s crust. Copper also exists as compounds in ores. These can be reduced using carbon in a blast furnace.

were born out of the Gilded Age. Two of these innovations directly pertain to Holmes‚ the murderer in The Devil in the White City. Holmes had built a furnace to burn his victims but discovered it could not achieve the heat necessary to accomplish this‚ so he had a new piece of equipment installed that could greatly increase the heat inside the furnace. Also‚ when Holmes was in jail‚ he wrote an autobiography that he wanted the public to read‚ in which he said he was innocent. This was an innovation

greatest Chinese invention is the development of iron and steel. The development of iron and steel led to other advances. In the 4th century the Chinese had developed blast furnaces to obtain cast iron from iron ore. The Chinese had access to large amounts of clay; clay was the most important ingredient in making blast furnaces. The Chinese also figured out that by adding a substance they called "Black Earth‚" they could lower the melting point of iron. Today iron and steel are used in many things
