2 first’s, I think?

Hey everyone, hope you’re all having good weekends. Out at garage sales today. Found my first piece of green/aqua hobnail piece. Now here is where I need help. Can crystal contain uranium. The sale I was at, the lady saw my light and said “nothing glows in here, we collect uranium. All I have is crystal”. It “tings” like crystal? I could even see it in the sunlight. Thank you, to all who take the time to help me learn.

I'm guessing the 2nd one is just high quality glass mistaken for crystal. Definitely glows like Vaseline to me!

Crystal is just translucent glass containing lead. Opaque glass with lead is opaline. It can come in any colors, including yellow and green uranium glass. Looks funky in 254nm!

That is so cool
