Is this cup safe to drink from? I got it from a thrift store, but then I found out about a vintage Garfield glass that contained lead and cadmium, and looks similar.
Get a lead testing kit, it's like a little marker that changes color when it detects lead. Rub it on the glass and paint and see if it picks anything up. Then you'll know for sure if it's safe or not.
that's a really good idea, thanks!
Here is an article on the Apollo glasses.

And a pretty detailed forum post.

There is no mention of lead in either link.
Imo if you suspect any cup of having lead I wouldn’t drink from it.
