This glass is made with amethyst frit and cobalt frit.  The cobalt turns an iridescent lavender when it’s incandescent hot.  It reminds me of the pinkish-lavender that some cobalt based underglazes have.    It’s hard to see the color in this light, because it’s so dark, but it’s intense dark blue with dots of violet.

I like the Iris Gold color because it’s unpredictable.  Sometimes it’s clear yellow, but it interacted with the amythest to create a shimmery blue in some lights.  It reduces to a mirrored finish, like raku glazes, but I prefer it translucent.

I combined Adventurine green with Iris Gold in this glass.  It didn’t have a favorable alteration.  Not bad, but not as exciting as the Amythest and Iris.

This glass is my first.  It’s so small that I use it to hold toothpicks.  It also has a crack in it, probably from a temperature change.  It held up through the annealing, so I think it will serve as a toothpick-holder for many years yet.
