Without the addition of other pigments, the glow powders will glow for up to 8 hours; however, you can add pigments to the glow powders. While it will reduce the glow time, it will also change to or add to the effect.
The most intense luminescent effect will come from the larger particle size powders, but for a smooth even finish on your product, you should go for the the smaller particle sizes. Sea Glow is 15-25 mm in particle size.

I could not get it to glow too much. You had to use a ton and it ends up making the polish too textured if you are attempting to use it with any pigment. All by itself, again lots used, it works just fine. Really pretty, but not as vibrant as the pic
I ordered an ounce of this powder and the bag of the powder does not glow much at all after charging it under a light. I have the original glow in the dark powder TKB carries so I had high hopes for this one... any tips to make it glow? It had a faint purple cast, but that's all. TKB Responds: The manufacturer is different, which might explain the different results. The only tips are to maximize the amount of powder and expose it to sunlight. It may be the type of light you are exposing it too doesn't activate it as much? We will do some testing of our own and see what we can figure out.
