Today I noticed that C**rs beer comes in screw-top metal bottles, so it occurred to me that I could possibly use them to store developer after disposing of the original contents (!). They're opaque to light, must be impervious to air passing through them, can be screwed tight shut -- what's not to like? Plus they old around 470 ml, which is a pretty useful amount (I wonder if this stuff comes in metal quart bottles?). And you'd have rapid heat transfer if you needed to heat or cool the solution. I'm only wondering how the bottle itself, or any sort of food-safe inner liner, might react to the chemicals in a developer. If I were in a college town, I could go dumpster diving behind a frat house and be set for life with these things. Anyone got any thoughts on the viability of using these to store chems?
