We've tested a lot of "glow in the dark" additives over the years, and nothing compares to Glow Worm.

I've been happily using one type of GITD additive, but last year I thought I'd test out some others to see how they compare.  In this experiment I tested the following phosphorescent additives:  Glow Worm, Europium Ultraglow, Art'n Glow, Glominex, HXDZFX Glow Powders, TechnoGlow, as well as Glomania ProFX GITD Paint, and GITD Nail Polish.  Of all of these, Glow Worm had by far the strongest glow, followed by Europium Ultraglow.  The GITD paints and nail polish barely glowed at all - what a waste.

I mixed in an equal amount of additive to Brilliant Resin and cast a 1" smooth circle with each.  I tested the basic white/yellow-greens, as well as some colored options.  Some of the powders sunk to the bottom while others stayed suspended. 

For the paints and nail polish (at the bottom of the board), I painted a thick layer on top of a clear cast piece. They all appear pretty whitish in daylight.

After 10 minutes charging in the sun, here's how they look in the dark.  It's hard to tell here, but while the top row looked about the same in daylight, the Glow Worm (top left) had a much stronger glow than the others. The greens and aquas all looked similar and all glowed pretty well, and I do like the purple/blue ones in the last row, their glow wasn't too strong but they were pretty.  The paler blues, the "pink" and orange were pretty ugly and looked much duller than in this photo. 

And here's how they looked after 1 hour in the dark, I hoped they would glow longer, but they do recharge quickly.

They look really pretty and colorful in the daylight while they still have a bit of glow, but they dull back down to the way they looked in the first image pretty quickly.

The stronger the glow, the more expensive it'll be.

Here's a bangle bracelet we cast in our Double-Sided Square Mold, using Black Resin Colorant along with GITD powder mixed into Brilliant Resin:

Here are some more of the awesome projects we made with our favorite GITD powders with Brilliant Resin and Clear Photo Film!

These eyes were made using 3 different GITD additives, the one on the top is Glow Worm. You can see how that one is more subtle coloring in the daylight for a pretty effect, but glows the strongest in the dark.

You glow girl!

I love this aqua colored glow-in-the-dark. It's a whitish powder I mixed into Brilliant Resin. The graphics were printed on our Clear Photo Film and cut into different shapes, domed with resin on both sides, then drilled for jewelry findings.  

Here's a simpler version, with just the creepy spider drops:

This piece can be made with or without the GITD layer, but looks entirely different from day to night.

Hop over to our Resin In Bezels post for more details.

And more in the traditional bright yellow-green:

This high-contrast look can be done 3 ways: printing images onto Clear Photo Film, painting by hand, or with clear-backed stickers.

STEP 1: Mix Glow In The Dark powder into Brilliant Resin and pour a thin layer in your mold. 

STEP 2: Pop out cast pieces, stick on clear-backed stickers/insert images/paint on designs, and dome them Up (click here to watch Doming Up how-to video).

The projects below were done the same way, but with images printed onto our Clear Photo Film.  The round NBC Jack Skellington pendant, the creepy skeleton pendant, and the skull keychain were made using the Doming Technique - clear resin on one side, resin with GITD Powder on the back side:

This skull was printed on Clear Photo Film as a black graphic, domed on one side with clear Brilliant Resink and then I mixed Glow Worm Green into the resin for the back side.  Makes an easy-to-find keychain!

The pendant on this spider necklace was made using our Medium Silicone Mold, the "beads" were made in our Silicone Cabochons Mold. For these, we printed these images on Clear Photo Film, and cast them in Brilliant Resin.

We then mixed GITD Powder into a new batch of resin, and domed up the backs. After 1-1/2 hours, I was able to embed the wire into the cast shapes. See this how-to video for reference on embedding wire in resin.

Here's another using an image copied onto Clear Photo Film, this one is in color and domed on both sides.  On the back I added GITD Powder, and embedded a pin into the resin as it was setting.  It looks very different from day to night.

 And what's Halloween without some eyeballs?!

These eyeballs were cast in layers (see this video for how-to's), then I painted designs on the outside of the castings with black nail polish.
