Jason is another fume master, creating amazing fumed rainbows in his work, but it doesn't stop there as he is an all around great glass artist as seen by the perfection in his marbles and the amazing dot worked backsides! The rainbow fumed thunderbolt wigwag in this one is BRILLIANT, and then you've that stunning sparkly dotted backside to go with it! Crazy sweet glass in a beautiful spherical package!
