The beautiful thing about digital art is that you can create with ease and complete freedom to experiment with worlds, materials, and processes that would otherwise be impossible in real life.
I'm no glassblower. In fact, this was entirely by accident while building something else in 3d. But I quickly discovered it look interesting and what started as one experiment quickly became a new exploration of glass settings to find subtle ways to add richness.
Thank you in advance for your interest.
