Let me see if I've got this one right. OP says, in good faith and with the aim of reassuring and calming people, that it doesn't really matter where or how you store your SN, as long as you don't screw it up completely and, say, leave it open or some other similar blunder. Yes, they admit that an airtight container is a good idea to prevent potential problems, but they insist that SN can last a long time even in bad conditions. Other users, however, argue that it's crucial to keep it in an airtight container, such as a hermetically sealed brown glass jar, especially if you plan to leave it there for a long time. So, I have two questions about what to do:
1) Do I leave it there, in the original container it comes in, or do I replace it with a hermetically sealed jar?
2) Wouldn't replacing the container be dangerous for the SN, because if I opened the original container to put it in the jar, I would expose it to air, which could turn it into nitrate?
I may need to order both the SN and the jar at the same time, so I'm asking this before I do anything. I'm also a neurotic, full-blown OCD fuckup, so this sort of thing drives me mad. Any help would be greatly appreciated.
