Syenite pebbles, containing fluorescent sodalite, were moved from Canada to Michigan by glaciers; [5] these glacial erratic pebbles have been given the trade name "yooperlite". [6] In other parts of the world, these types of rocks are known as sodalite-syenite and occur in Canada, India, other US states, Greenland, Malawi, and Russia. [citation ...
Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of ...
Radioluminescent paint is a self-luminous paint that consists of a small amount of a radioactive isotope (radionuclide) mixed with a radioluminescent phosphor chemical. The radioisotope continually decays, emitting radiation particles which strike molecules of the phosphor, exciting them to emit visible light.
Sodalite (/ ˈ s oʊ. d ə ˌ l aɪ t / SOH-də-lyte) is a tectosilicate mineral with the formula Na 8 (Al 6 Si 6 O 24)Cl 2, with royal blue varieties widely used as an ornamental gemstone. ...
First, it will be useful to introduce some mineralogical terminology for gemstones that can glow when exposed to light, friction, or heat. Note that the following discussion will omit modern techniques such as X-rays and ultraviolet light that are too recent to have influenced folklore about luminous gems.
Stars made of glow-in-the-dark plastic are placed on walls, ceilings, or hanging from strings make a room look like the night sky. [29] Other objects like figurines, cups, posters, [30] lamp fixtures, toys [31] and bracelet beads may also glow. [32] Using blacklights makes these things glow brightly, common at raves, bedrooms, theme parks, and ...
Cordierite or iolite is a magnesium iron aluminium cyclosilicate. Iron is almost always present, and a solid solution exists between Mg-rich cordierite and Fe-rich sekaninaite with a series formula: (Mg,Fe) 2 Al 3 (Si 5 AlO 18) to (Fe,Mg) 2 Al 3 (Si 5 AlO 18). [3]
A glow stick, also known as a light stick, chem light, light wand, light rod, and rave light, is a self-contained, short-term light-source. It consists of a translucent plastic tube containing isolated substances that, when combined, make light through chemiluminescence. The light cannot be turned off and can be used only once.
