This powder has a pretty significant amount of glow to it. As with other glow powders, the more you use, the better the glow.
It doesn't really melt into the glass though, so you can roll it in the powder and get a coating and get it to melt onto the surface to stick, and give a frosted effect, which is not unattractive by itself.
But the best way to make it really punchy is to create a hollow space inside the bead or whatever you're making, spoon some of the powder into it so that you get a goodly amount, and then cover it back up again.
It's cool to watch it glow briefly when you push the glass into the powder.
Compatible with both soft glass and boro.
