New storage container 3 months later...
A bit more than 3 months ago I put this old jar to use to hopefully stop patina from forming on my razors in the shave den ( http://straightrazorpalace.com/works...shave-den.html ). I am happy to say there has been no spots since putting the jar to use. I guess anything with a decent seal and some desiccant beads for moisture removal would do the job.
