Any further clarification as to why aluminum foil shouldn't be contacting blotter? All my blotters are wrapped in foil at the moment... am I destroying my LSD stash and not realizing it??!
No, don't worry. Tinfoil is fine. I don't know were the idea that tinfoil is bad comes from, but it's not true.
I have some comments to this thread.
First, I'm not so sure that oxygen absorbers are that great to use, I suppose it depends on what kind you've got. (sorry for exacerbating your OCD, Kishka)
From wiki:
"
The moisture requirement of iron-based scavengers makes them ineffective in moisture sensitive applications."

I'd love it if someone more savvy in chemistry, who has a better understanding of the process of rusting, could tell us if that process is actually a good thing to have going on beside your acid.
Best case it'd actually just not work, because the dessicants taken all the moisture in the first place. Think about it, you never get a dessicant and an oxygen absorber in the same food package, it's always one or the other.
I've personally chosen to only go with dessicants, and no oxygen absorber. But I'm using argon too at the moment, which is probably overkill and quite finicky to work with, And there's really no way of knowing if it makes a difference. So I don't know if I can recommend it (if you're planing to store something for 30 years+ it probably is a good precaution though.)
Secondly, on the topic of fridges and freezers. I don't understand how people dare to put their blotters in there. I put my blotters in the fridge with a lot of dessicants for some months, and when I took them out the dessicants were all soggy. That is not a good environment for blotters!
I'm keeping all my "powdered" chemicals in the usual amber vials in the freezer and that's worked great for many, many years. So I don't know really..... has any one here really managed to keep their blotters completely dry in a freezer? Because there's no point in keeping them at -20 c if they get exposed to moisture, which is much worse than a little heat imo.
