    Dave, I already answered this today, vaguely, anyway. You just can't
    ask me questions like that - I have this intense curiousity, you
    see. What I wrote earlier has one general formula that may mean
    something. Otherwise if you're interested I'd say to search Google
    and Wikipedia (which doesn't have a whole lot) for ammonium
    fluoride, ammonium hydrogen fluoride, maybe potasium hydrogen
    fluoride, and maybe bifluorides in general. All of those things are
    still quite toxic and dangerous, but nothing approaching HF itself.
    You'll also find that they are precursors to chemical weapons, which
    affects availability, these days. It's curious that you would mix
    what you have with peroxide, though, because that's an oxidizer and
    fluorine is already the baddest oxidizer on the block - maybe
    there's something going on there, though. I enjoy chemistry
    (actually, I love it), but I only go so far-not a pro or anything.
