At our club meeting, one the members brought,
what he hoped, was an example of using glow-in-the-dark
glue. It was part of a discussion of finishing and
he brought along some short pieces and what he
thought was a black light. Turn lights off, turn light
on - no glow. But he had tried with another bulb
in the shop, so the demo will go out to another day.
But curious if anyone else has used the glue and how
you liked it. Did it help in your finishing? And
what kind of bulb did you get anyways?
true glow in the dark doesn't shine under black light. it gets charged from
normal sunlight, then gives that light back slowly. the good stuff is really
a very fine ceramic powder which can be used or mixed with things. i've used
it in my glasswork, ex:
between layers of glass. depending upon which color you want to radiate, the
powder is a different color. the blue and green versions are a pale green
but mostly white colored powder. it doesn't work well in extremely thin
layers, as it doesn't glow very much.
mixing it with non-clear glue would make it not glow very much, since it has
to 'see' light to absorb it, and the glow would be hidden. if used in a
clear glue, then it should work unless the glue blocks UV (like spar
varnish), in which case, it won't glow.
You need a long wave ultraviolet fluorescent lamp -- the
incandescent ones are useless. A short wave ultraviolet
lamp, such as those used for erasing EPROMs or disinfecting,
will work, but may also cause cancer, skin damage, or
eye injuries if you're not shielded from it.
