The only danger is if it gets inside your body, and even then its minimal because the glass is like 1-3% uranium. Now I probably wouldn’t store food or liquids in it for long periods, especially acids to avoid leeching.

Uranium is an alpha emitter, so its radiation doesn’t go through skin or most materials, and it has a half life of a few billion years, so its not very radioactive.

I wouldn’t eat or drink off it, not because of any danger, but because this stuff is incredibly brittle and will chip or crack at the slightest of mishandling, and a replacement could be hard or impossible to find because it stopped being produced around the WWII era.
