In the reaction between aluminum and iron(III) oxide, this forms iron and aluminum oxide and releases a lot of heat: 2 Al(s) + Fe 2 O 3 (s) → 2 Fe(s) + Al 2 O 3 (s) ΔH° = -850 kJ. So, the reaction illustrates combustion of iron oxide, oxidation, and also oxidation-reduction because one metal becomes oxidized as the other is reduced.

Iron red glazes are easiest in high-temperature reduction firings, it is just a matter of saturating a transparent base with 12%+ iron oxide to create a "beyond Tenmoku " (Tenmokus have about 10% iron). That being said, iron red glazes are most commonly found in the cone 6 oxidation range, likely because it is a much more accessible process.
