Red iron(III) oxide - Fe 2 O 3 . Black iron(II) oxide - FeO At high temperatures, Fe 2 O 3 starts to break down so O and F take off and you are left with the FeO. In oxidation, this is how you get those cool "oil spots" happening on the glaze where Fe 2 O 3 is converting and free O drags F to the surface and leaves it there.. Someone can probably get you more detailed description of the process.
