Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide converts iron oxides to elemental iron. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide.

Limestone or quartz is often most used as ballasting because it is a hard stone that will lock together providing for extra strength. According to Brian Solomon''s book Railway Maintenance, The Men and Machines That Keep the Railroads Running , today''s trains can exert a force of 100 psi when passing over track and the stone used for ballasting must be able to withstand this constant abuse.
