Looking like an embryonic universe, this complicated marble starts with a core of Van Gogh Caramel art glass. Then lines of Gold Aventurine were snaked across the surface, followed by blobs of Clear Dichroic that was dipped in Light Blue Glow Powder. All was then encased in Clear glass, which preserves the three-dimensional details and allows the clouds of glow dust to float through the volume. The luminescence of the powder is shown in the second photograph.
