Hmm I wonder if anyone sells fluorescing wood dyes?
Something to consider.
I know there are glow in the dark spray paints that are largely clear… and that would fluoresce strongly of course.

It could be a good way to sign a careful reproduction of a famous piece. They sell just such security inks to identify your stuff if it is stolen.
I could think of many interesting artistic ways it could be used though few folk would know.

I’ve actually done this out of curiosity. results were boring as one would hope.
We actually have some anodized aluminum that instead of a color, is done in a dye that fluoresces. I’ll see if I can find/take some pictures later.

Horrible phone pictures, but you get the idea.
How they look under regular light. The UV anodization is a clear/milky color. If you didn’t know what they looked like with nothing, you’d probably think there was nothing on them, but side by side with a plain one, it becomes obvious. Etched with the GF, you get a light marking one them like this
Put under a BL, and the markings show up much better, and everything looks like this.

I once had a class in anodizing and it is not all that hard particularly if you can have a setup you can leave like a set of cabinets you can just leave when not in use. All it was structurally was a battery charger with a car ignition coil to smooth out the waves and a number of glass tanks with tops for each different color and a clear stop.
By putting the material slowly you could even get a gradient and do so again upside down and you get that gradient between two colors.

Well I just now got my UV light and sure enough the Yellowheart screamed which was great as I had no idea it was yelluwheart but was one of many whitish woods, but there was so much more! Suddenly all those generic white woods differed a lot, the white glue that was not sanded away stuck out like a sore thumb. Maple was much brighter than poplar, but the really special treat was redheart that went from barely discernible from paduk to amazingly rich incredible colors,
zebra wood also fluoresces.

Really? I do have a piece but I don’t remember seeing it glow. I’ll have to go back and double check.

Many, including Zebra wood are not a glow that smacks you in the face the way Yelloheart does but several pieces that appear the same color in regular light are very different in the new flashlight i have that is not really dark but contains a lot of uv. much of it is subtle but like Zebra wood the color differences in the dark and light is much sharper as the light areas kick back more light and the dark bands do not;
