Uranium glass, renowned for its distinctive glowing green-yellow color under UV (ultraviolet) light, is frequently called “Vaseline Glass.” But what is the origin of this unusual nickname?

The combination of skilled craftsmanship and the natural uranium deposits nearby made Czech uranium glass a hallmark of quality and beauty.
