Main Question or Discussion Point

Hello,

The explanation for this, min 0:54

is that you have Fe2O3 in the match head, and after burning it, pure iron is obtained
2 Fe2O3 + 3 C -> 2 Fe + 3 CO2

I think the chemical explanation is fine, but I don't understand why Fe2O3 is added (as colorant, if the red phosphorus is already red).

Thank you for your time.

I just tried it with an ordinary wooden match and it wasn't magnetic after burning.
