    Take a deep breath, sit down, get comfy. I'll say that I'm a good
    amateur chemist - any pros want to speak up, I'll certainly defer to
    that. And that I don't actually know this off the top of my head,
    it's research. And the easy answer is I don't know what your blue
    crystals are. You have acetic acid and hydrogen peroxide - those are
    your reactive agents. Those put together under certain conditions
    make peracetic acid, which is an organic peroxide. Peracetic acid is
    linked to polymerization, benazene, alkynes (acetylene), and alkenes
    (methyl ethyl ketones). In other words, that organic peroxide steps
    across the line from simple inorganic chemistry into much more. What
    this means is pretty simple: if you put iron into acetic acid,
    you'll get iron acetate, which is red. If you add boron (boric acid)
    which has a green flame test, well, that's what's called a metalloid
    - it can go AC or DC depending on the circumstances. Plus it's
    trivalent. You get into boranes, adducts, perborates (from/with H2O2)
    Then you throw in hydrogen peroxide, which is just aching to get rid
    of that extra oxygen (H2O2), and you have quite the soup mix - an
    organic acid with a peroxide with a trivalent metalloid and iron,
    which is chemically versatile to begin with. It's well beyond my
    ability to sort out, but I'd say you're looking at a more complex
    molecule than something like "iron acetate" - more like "iron
    dihydrogen tetraborate", which I just made up, that's not a real
    thing, most likely. I will say that acetates tend towards the blues
    and greens, though. Otherwise that should make it all very clear,
    right? HAHAHAHA.......
