    Check at a welding supply store for how much a small bottle of Argon costs. It's inert, and is used for heliarc welding.

    "... a few one gallon ... jugs ..." Marbles by the hundred weight.

    My guess; quarts or liter size glass will serve much better. Pay
    attention to those that may be well sealed and keep them
    well sealed. My bottles use the PE cork-with-screw caps
    knowen by the names Polycone or Polyseal. I think they
    are the surest seals money can buy. Dan

    In my experience the 'Vac-u-Vin' type stoppers hold their seal for several weeks - especially if you wet them before forming the vacuum. There may also be another advantage in vacuum sealing photochemicals. I have noticed the tiny bubbles forming when the vacuum is applied probably representing dissolved air coming out of solution in the partial vacuum - less oxygen for oxidation.
