what kind of glass tiles will glow under a black light?

Answer 1

not sure if they make a glass tile that will glow under black light, but maybe put in regular glass tile, and get some fluorescent paint, in a clear color and using a toothbrush or any small stiff bristled brush, you could "flick'" small speckles onto the tiles...just a thought..
good luck

ok..update...i was just corrected by my other half, he says any white or pastel glass tile will glow...i would do a test run first....
good luck..
