Mass fraction of solids in the protoplanetary disc around a star with a solar mass and composition for both iron oxidation models. The mass fractions are normalised such that all considered species add up to one. FeS condensation occurs around 0.05 AU while fayalite condensation occurs at 0.15 AU. The condensation of water vapour into water ice happens just outside of 1 AU in the disc while CO₂ condenses out outside of 10 AU.
