2% although some 20th-century pieces were made with up to 25% uranium.

Uranium half-life […] varies between 159,200 and 4.5 billion years

Oho? So they will keep glowing for a while?

They don't glow. That's misleading. Uranium salt just makes a cool green color.

The glow is it fluorescing under UV light, like glow-in-the-dark UV paint if you have a blacklight. It's not a result of internal radioactivity.
