    Mr.Binnion you are correct about the oven in essence being hydrogen
    and nitrogen. 

    I for time sake didn't expand my last comment. The atmosphere is
    generated by flowing ammonia vapor through a heating retort at 1750F
    or lower depending on the metal producing a protective atmosphere
    composed of 75% hydrogen and 25% nitrogen.The working factor here is
    the gasses dissassociating oxygen from the atmoshpere inside furnace
    and being vented through a iconel muffle.No oxygen,no firescale or
    oxidization,etc. 

    I would say that dealing with the changing of the ammonia tanks is
    dangerous and you could dry clean your lungs or lose your sight or
    even burn your skin. So a protective plan of procedure and protective
    gear has to be in place to eliminate risk. 

    I would say my biggest problem with ammonia is the whole security of
    it.I basically have a huge welded cage with specialty locks and also
    a motion detector in the cage.You see it is a key component in the
    manufacture of meth.I worry more about the ammonia and fittings being
    stolen rather than the all the metal and such in our vault.It's a
    ongoing game here because one day they will drill out a lock,then 6
    months later they will try to cut there way in,etc. They are
    relentless in there effort and each time I keep stepping up a
    notch,because nothing is invincible and its relatively about slowing
    them down till the police can arrive.I think I am gonna get some
    razorblade wire next and maybe a pack of wild wolves to hold them at
    bay for a couple of more minutes.
