Customer brought in a conservation print on cotton paper that has a 'surprise' image of glow-in-the-dark paint. She asked if the enhanced light filtering of conservation glass would keep it from glowing brightly. I have no idea. On one hand, I'm sure many such prints have been conservation framed and show just fine. On the other, I can imagine it stealing some brightness. She's keeping it in a room without natural or flourescent lights, and wants to use whatever keeps the glow bright.

What say?
 
Yes, the UV block will stop the glow-in-the-dark paint. I have "February Stars" by Dan McCarthy as a sample on my wall and the stars are suppose to light up at night. With Museum Glass there are no stars lighting but I would rather preserve the art than the glowing stars - it is a beautiful piece.
 
The range of invisible radiation blocked by UV-filtering glass and acrylic is 280 to 380 nanometers.

Visible radiation that we call light (ROYGBIV) goes from 400 to 700 nanometers, and then there's a transition range from 380 to 400 nanometers, where the radiation goes from invisible ultraviolet to visible violet, which would be either invisible or nearly so. That is, 400 nanometers is visible, and visibility diminishes to zero at 380 nanometers.

According to my Google search just now, "black light" lamps emit radiation somewhere between 320 and 400 nanometers, so a "black light" would illuminate little or nothing under UV filtering glazing, because it emits invisible radiation that is nearly all blocked.
 
What Joe said is spot on, we have a sample box of AR99 glass on one half and normal on the other and a glow in the dark butterfly inside, when under the UV lamp provided only the half under the regular glass glows!

I am not sure if that's what Jim said it was a bit technical for my limmited intellect :)
 
Thanks, all! I just did a general search on the subject, and this thread popped up, so your comments will also be helpful on a wider scale.
 
If I'm not mistaken, Shayla's original reference was to a "glow in the dark" image, which I believe is phosphorescence (storing light and re-emitting it), as opposed to fluorescence (glowing when exposed to "black light"). I don't know the science involved, but I believe the glow-in-the-dark property would be "charged up" by exposure to visible light, so might not be hindered (much) by the filtering properties of UV-filtering glazing. https://www.differencebetween.com/difference-between-fluorescence-and-vs-phosphorescence/

A local artist, Tom Bacher, creates paintings incorporating phosphorescent pigments, so that the scene has "daytime" and "nightime" effects when viewed in light or when the lights are switched off.
When I was in college and first started working in framing at a local art gallery, Tom was one of my co-workers.

Mist of the globe in the dark paints get there energy from UV light, yes some energy will come from visable light or heat but mainly from UV.
What's more interesting here than any of that is that all this is the same energy source just vibrating at a different frequency and different wave legnth (That's what Jim's NM was about) light is photons which makes up an array of stuff we know and love, like radio waves :) microwaves UV and infrared, yes light bulbs do emit radio waves the new leds only produce light of the correct wavelength and frequency thus reducing the energy consumed, :) awesome!
 
I framed a Painting on velvet that had a glow in the dark surprise image and CC glass did not affect the surprise . But for Florescent paint Jim Is correct .. Glow in the dark and Fluorescent paint are two different things completely.
