Neutral Sky Blue Glow Powder

  • Sale
  • Regular price $ 7.95

This phosphorescent pigment is white during the day and glows a bright blue color in the dark. If you are looking for a brilliant pure blue glow color, your search is over. This color is just below aqua in terms of brightness and glow duration but is the closest to a true blue that you can get. Our fluorescent blue emits a very similar blue to this one, but as it is dyed with fluorescent powder, it does not glow quite as brightly.

All of the glow powders sold by Art 'N Glow are encapsulated which means that they can be used in both solvent and water based mediums. Some of our competitors sell non encapsulated powders that will deteriorate in water based mediums (such as acrylic paint medium).


  • Glow Time: 6 hours
  • Size: 20-30 um (micron)
  • Material: Strontium Aluminate
  • Uses: Resin/rubber/plastic casting, glow paint pigment, molten glass, etc.
  • 1 ounce = 30 grams
  • Best charged in the sun or with an ultraviolet/black light

Holds up to the heat

Im making glass marbles using boro and if im careful i get a deep glow thats unlike any glowing glass i have seen. The time in the flame will affect how long it will glow but its always a bright glow for however long it lasts.
Customer service here is quality all around!!!!

Hi! Thank you for your feedback :) Our glow in the dark products must be charged with either sunlight or UV light to see their brightest glow - regular indoor lighting is typically not strong enough to charge most of our glow colors to their full potential. Try taking your glow product outdoors into the sun for a few minutes, and then bringing it indoors to a completely dark room to see its true glowing effect. With a full charge we would expect our Neutral Sky Blue glow powder to glow up to 6 hours on a full charge from a UV light or sunlight. If this is not your experience, please reach out to us at and we would be happy to be of further assistance :)

So far, Blown Away!

Ok, so I purchased the Green and the Blue Glow pigment.
I got one for free on a facebook ad and I figured Free was good enough to try.
I had no idea it would glow so bright!
It's way better than I expected.
It's so bright, yesterday I walked by the basement and something caught my eye....

It was the small bag of green glow powder, shining in the darkness like a night light that I saw from upstairs.

So I'm sold.
It seems like it glows "Too Much" if anything lol I feel like it's going to run out or something :)

I don't know how long the glow effect last,, It's been several days so far.
I hope it continues to be so brilliant after I run it through the 3D Printer resin, but I'm very optimistic.

Hi Neil,
We really appreciate your feedback! Rest assured, that vibrant glow you are seeing will last a very long time :) Our glow in the dark powders can be recharged millions of times. Even after ten years, they will retain 90 to 95 percent of their original light storing and emitting abilities.
