| History of Iron Oxides | ||||||||||
| There are two theories about how iron oxides were discovered. | ||||||||||
| One was that Prehistoric man came across hematite, mistaking it for copper pyrite, which was used for tools. When the hematite was smelted it formed iron metal, which over time would react with the oxygen in the air to form iron oxide. The second was that a forest fire melted iron ore in the ground, producing iron metal which would then react with the oxygen in the atmosphere to form iron oxide. Therefore, wherever there is iron metal exposed to the air, there will be iron oxide. | ||||||||||
