Glow in the dark powders can be mixed n with clear resin or other medium to create products that glow at night. The glow lasts anywhere from 6 to 12 hours depending on the type of charge it gets and the quality of the charge source.
It can be charged by the sun, CFL light bulb or black light.
Nighttime Glow powders are generally very light cream or beige that glow a particular colour when exposed to a source of light like the sun during the day, absorbing the energy of the sun and glowing in the dark at night. This effect can also be achieved with the aid of a black light. When the uv rays are exposed to the glow powder or paint or art work, finger nail etc, it glows in the dark.
