I found it at an auction in a box lot 20 years ago or so. I jokingly tell people it's a suppository when I hand it to them, just to see their reaction. It's roughly 2" long. The top and bottom unscrew. One side is metal and has cork material in the center. The other side is hollow and made of brown glass. I get the impression that it's supposed to hold liquid, but I don't know. There are absolutely no identifying marks or makers marks on this.

Any ideas?

That's a reusable thorium capsule, once used as an experimental intestinal cancer treatment. It was filled with radioactive material, usually thorium but sometimes uranium or radium, then ingested. Obviously they couldn't use gel capsules as the caps would dissolve and the material would come into contact with the intestinal walls. I just made that shit up. Have a nice day.
