It is so hot in the blast furnace that carbon monoxide is the reducing agent which reduces the iron(III) oxide. The equation for the reduction of iron(III) oxide in the blast furnace is: ...

We obtained aluminum powder by filing down old soda cans. We chose to use iron(III) oxide, or Fe 2 O 3, known more commonly as rust. We got rust off an old corrugated iron shed at the sawmill.
