vintage Rainbow label crackle glass top hat, amberina glass w/ cadmium glow under UV light

Amberina crackle glass top hat, hand blown art glass with the original Rainbow label 1970s vintage.

This has a great glow under black light. I'm just using a blacklight flashlight here for the photos, and look at that color.

This is a tiny vase, or a toothpick holder? Looks kind of like a mushroom! Condition is excellent, no damage or wear.
