For my first iteration, and tried to disperse the glycerin around the block of rockite, which resulted in some hot glycerin all over my hands. I like how the glycerin acted as a lens within the rockite, filtering light and giving everything a gentle purple glow. For my second iteration I decided to concentrate the glycerin on one side of the block. This caused my to loose the lens affect, but I like the even hard edge of the glycerin against the wild curvy edges formed by the balloons. Elena chose to do a mixture of the two styles, concentrating the glycerin while also smoothing it out within the curves.
We also included sections of our blocks, which are shown above.
