  • Patent number: 7252889
    Abstract: A method of fabricating glow-in-the-dark gazing globes or other objects, as well as the articles that result. The method comprises the steps of providing a hollow form having an inner wall made from a transparent or translucent material, the form including an aperture for gaining access to the interior thereof, and introducing one more photoluminescence or phosphorescent pigments into the form through the aperture so that they cling to the inner wall. In alternative embodiments, the pigments may be applied without an adhesive, as by naturally cling, vacuum evaporation, or other techniques. In a gazing globe embodiment, a stand may be included. In the preferred embodiment the method further includes the step of applying an adhesive to the inner wall of the form prior to the step of introducing one more photoluminescence of phosphorescent pigments.
