Ice dwarfs are celestial bodies in gravitational orbit beyond Neptune. Dwarf planets have enough mass to maintain their round shape, but not enough to become gravitationally dominant in their orbit. Pluto was reclassified as an ice dwarf in 2006.
Glass Eye Studios in Seattle, Washington handblows their astronomy paperweights using dichroic glass and ash from the 1980 eruption of Mt. St. Helens.
Dichroic glass is an optical metallic oxide glass developed by NASA to protect sensitive equipment from cosmic radiation and to protect astronauts from harmful unflitered sunlight while in space. Extremely thin layers of metal are vacuum deposited on glass and the layers permit some light and color wavelengths to pass thorugh while deflecting others. This produces a chameleon effect in which the color of the glass changes with the amount of light being absorbed or reflected.
