Hey drunkards, question

[Ecrofirt]

I bought a decanter at a flea market this weekend for $.25. The thing is nice, but it's lacking a lid.

I don't have any other decanters to compare it to, so I need some stuff answered:
Do decanter lids usually fit snugly or loosely? This isn't a wine decanter, btw. It looks a bit like this:

If the lids fit snugly, what material is usually used to keep them snug if not glass? I've got 2 lids that almost fit, but both leave room for a bit of air to escape, and I'm thinking I can coat them in wax or rubber or silicon or something or other. Alternatively, I can probably find a cork that'll fit this.

Speak up fellas.

I think you are looking for a particularly solid wax.  In my experience, the lid fits snugly, but not as tight as a cork.  Tight enough to keep the air out, but loose enough to be able to remove easily.

It probably depends what sort of alcohol you are going to be putting in there. I think I've seen both types of stoppers. I am by no means an expert on the subject though.

No no, that's not mine. That's just a similiar looking one that came up in google.
