    Glow-in-the-dark pigments have come a long way from the yellow-green glow of the 1970s. Modern pigments come in a rainbow of colors and have applications in more than just fun and crafting. With both novelty and safety in mind, mix these pigments to paint clothes, add to cosmetics, and use in industrial applications. From spooky Halloween funhouses to hazardous warnings signs, glow-in-the-dark pigments can make your environment more fun and safer.

    Things You'll Need

    • Glow-in-the-dark pigment
    • Clear paint medium
    • Mixing container

    Choose an environment that is dust-free and has low humidity. For best results, the process should be as moisture-free as possible.

    Pour the paint medium into a clean container. Pour only an amount that will be used within an hour. The glow-in-the-dark pigment settles to the bottom of the paint if it's allowed to sit so only mix what you'll use.

    Add the glow-in-the-dark powder slowly while stirring the medium. Generally, your mixture should be 10 to 50 percent powder by volume, but this depends on the powder particle size and the amount of glow desired. The more powder you add, the brighter your paint glows and the less smooth the painted surface appears.

    • For best results, use a clear paint medium. Color pigment in the paint medium obscures the glow-in-the-dark pigment's luminosity and dims your glow.
    • Buy a water-based medium to avoid harmful fumes, but make sure your pigment
    • Pigment is measured by the ounce and paint is measured by the fluid ounce. Keep this in mind when you calculate the percentages of volume in your mixture.
    • Add more pigment if you're painting on a colored surface.
    • Paint a white background on the surface where you plan to apply the glow-in-the-dark paint. If you're painting colored clothing, use white fabric paint as a background where you're using the glow-in-the-dark paint.
    • Solvent-based paints can be used to mix glow-in-the-dark paint but are flammable and shouldn't be used around children.
