Help identifying UV acrylic

[thehadmatter]

I have three large scrap pieces of TruVue acrylic I have found as I was cleaning the shop recently. Is there a way to identify if they are premium or UV? Also found a box of Water White. What is this? Thanks for the help.

WW is DenGlas. Beautiful, premium low iron glass that is quite clear. No UV Protection.

Does the plexi have it's covering? Any identifying writing? ie OP-2 OP-3?

Got a blacklight? white tshirt on one side of plexi? does it glow purple? Not UV. Does it look white, might be UV. Good for a quick denial, but nt conclusive for a "grading" of OP-2 or OP-3. And fun, everyone likes blacklights

Thanks on the DenGlass. Now I'll have to figure pricing for it. And is there any particular use for it, is it better in any giving situation?
As far as identifying marks on the acrylic, no. Just a sheet of acrylic, my guess is previously used, but not certain on that.
Now I just have to drum up that black light we had in the 80s as kids! Maybe I'll find some of my old albums too. That should make for a fun afternoon!

So sheets of uncovered, used plexi? Scratched? dirty? Filthy can you really sell it as premium?

Artists love(d) DenGlas. Where UV protection isn't needed but no glare is use the Den. It cost more than Museum when it came out, but since you "found it" it cost you nothing. Sell it at something between CC and Museum, maybe the price of NG-CC.

Good points, may best be used to enhance the trash bucket.
Thanks for the help with the water white.

You don't necessarily have to throw the acrylic out.

I have many artist clients who would love to use the acrylic for palettes or for etching.

Why not give it to them instead of throwing it away. Keeps it out of the landfill.

Plexi scraps also make real handy cutting surfaces

One end of my workbench is covered in acrylic with things like a year planner ...... and half-used blades ..... and stuff, under it.

Re testing for UV blocking on acrylic . . .

Does this give a slightly yellow hue when UV acrylic just placed onto a piece of white A4 paper ? (With no UV light applied.)

Like a piece of TV CC or Guardian inspiration both show a yellow hue.

This yellow hue look looks more pronounced when viewed with UV light going through the glass onto white paper, but I suspect this is more a trick of the UV purple glow, and the effect on the viewers eyes.

Cheers,
Les

Bump . . .

Has someone that uses the UV light test done this on UV acrylic ?

Yes. The results are about the same for UV filtering glass and UV filtering acrylic.
