Stained glass kaleidoscopes by kaleidoscope artist Bob and Grace Ade are crafted from modern art glass. These kaleidsocopes showcase lovely fused glass exteriors and vials for the object chambers. Playtime has an interchangeable vial for you to play with your own glass objects and create your own colors. Interior images are icily beautiful when polarized light is put into play. Within Ice Flowers, the oil cell is polarized which means there is a refraction of light that enters into the cell. For example, the northern lights are polarized light. Another favorite piece designed by Bob is the Jewel Kaleidoscope.
