The basic ingredients of iron making – iron ore, limestone, and carbon fuel – are some of the most common on Earth, but are not found everywhere. Early furnaces were built where these materials were available. Iron is usually found in combination in the form of hematite, the magnetite used at Hopewell, or other iron ores. Most iron ore was ...
