Most of it is safe to have in a display case. I have an antique uranium glass photo filter that's hot enough that I keep it in a metal box. All of the pieces I have put out enough beta radiation to easily detect. I don't have an alpha counter.
You wouldn't want to grind it up and inhale the dust. I winced when I saw someone on Etsy selling uranium glass shards they'd tried to reclaim from broken pieces by putting them in a rock tumbler to make them look like beach glass.
I wouldn't recommend actually eating off of it either, but most of it is so old and fragile you'd probably want to avoid that anyway.
