Glow In The Dark Pigment FAQ
How do I make a glow-in-the-dark paint?
Strontium aluminate pigment powder works with most clear or translucent mediums - acrylic, resin, epoxy, varnish, nail gel, candle wax and more. Mix at a 1:4 ratio (1 part pigment to 4 parts medium) and stir well. Going above a 1:3 ratio causes the pigment to clump and reduces glow performance.
How to charge glow-in-the-dark paint & pigment?
Hold a UV flashlight close to the surface for 10-30 seconds, or place your piece in direct sunlight for 1-2 minutes. The pigment starts glowing from the first second of light exposure - the longer you charge, the longer it glows. You can't overcharge it.
What do 0–30 µm and 65–95 µm mean?
That's the size of the grains in the powder. Fine (0–30 µm) mixes in smoothly and dries with no texture - best for paint, thin coats, nails, and detail work. Large (65–95 µm) has bigger grains that hold more light, so the glow is brighter and lasts longer - best for resin, casting, and walls or concrete. Both are the same pigment, just ground differently.
How long does glow-in-the-dark effect last?
Glow duration depends on the colour. The brightest pigments - greens, yellows and blue - glow up to 12+ hours after a full charge. Oranges and white glow for around 6 to 8 hours, and deeper tones like pink and purple glow for about 4 hours. All colours recharge instantly and never wear out. The exact glow time for each colour is shown on its product page.
How does strontium aluminate pigment work?
Strontium aluminate is a special crystal that absorbs light and stores it as energy. When you turn the lights off, it slowly releases that energy as a visible glow - this is called phosphorescence. It works the same way as cheap zinc sulfide pigments, but stores far more energy, which is why it glows brighter and for much longer.
