Great looking Kryptonite, Juno. I love that you got the obsidian flaking glass look to it, and the colour is fantastic. Great translucency, too. Consider me impressed. :thumbsup
Seems we all have Kryptonite on the brain lately, because I've been playing with the Castin' Craft too.
Mine's about 3" diameter by 1.5" tall. I found a candy container with a nice faceted shape and made my first resin prop this week. I've been trying to think about what else I'd like to make out of Kryptonite for days...
