In rod form, this unnamed glass* is a very nice tanzanite blue colour but upon heating and after annealing it turns into a very intense cobalt blue. The glass is a cloudy transparent.
The glass worked fine and I had no trouble with it.
The beads were photographed indoors in natural daylight.
* There's only a very small amount of these glasses that have a number instead of a name. Because there's only a tiny amount of each one Kathy at CiM didn't feel it was worth naming them.
