Glow in The Dark Powder Pigment 1oz (28g)

This powder glows VERY bright! It is incredible, I stuck the bag under UV light for 30 secs after I recieved the package and took the first picture. Its glowing bright enough you can see the details of my hand. But, I bought this to add to a 3d resin printing project. The particles are too heavy, instead of being suspended in the resin evenly the glow powder sinks to the bottom of the vat. The first few layers of the print will lift the glow powder, but everything underneath won't get any powder after that. So the first few layers of the print will glow super bright, but the rest of the print will only have a small amount of powder. In my particular case this worked out, because I only needed one side of the print to glow, you can see in the second picture the top glows brightly, but the middle and back are really only being lit up by the glow from the top layers. If you are looking at this and thinking about adding it to a resin print, I would suggest looking for a different solution. Finding a powder with a finer/lighter particle size would be ideal, but thats not really info that many manufacturers release. Personally I will be trying glow-in-the-dark alcohol based inks next, as well as picking up some premixed glow resin. If you are still thinking about this for a resin print (Good for you! Experimenting is fun!) then I have one last bit of advice: make sure you have a fresh FEP film on hand, because this powder will scratch up the film in your vat. Also don't dump the powder contaminated resin leftovers back in the bottle, it will contaminate the whole bottle. Probably shouldn't put it in your resin left-overs bottle either, just try to keep it seperate from everything else really. So 5 stars because it is an insanely bright glowing powder.
