Color Shifting Glass

A few years ago, I made this box for my friend. It's kiln cast with a type of crystal that shifts in color under incandescent and florescent light. This is a special glass; most glass colors don't have this property.

In college, there was a student that claimed that their pink glass was stolen out of a box stored in the basement. It caused unnecessary drama for a week because after moving the box upstairs, the "missing" glass magically reappeared.
