Partial write-up teaser below:

This work was carried out with iron (_) _____ in _% distilled _____ acid. I've read that by using two different acids with roughly the same affinity for iron (or a metal in general) it's possible to bring about metallic decomposition in an easier manner.

These images are from the second distillation cycle. I did not dry distill the first run. It was distilled to near dryness (a red gum like mass). The distillate was poured back over (cohobation), and the distillation was repeated (this time it was dry distilled).
