Love that! I’ve got some of that decal paper somewhere around here and never bothered to try it out. Lovely effect though…I might need to see if I can find it.

I’ve never heard of this material, but looking at what you have done with it on a first try, I’m sure it would be possible… ‘3D’ effect is a bit vague, but i immediately thought of putting the kite on a separate layer that slowly slides back and forth… and that thought, coupled with the antique look of the photo made me think of this still-photo animation:

there’s a local museum / shop here that features local clay and glass artists. one of them does these really interesting montages of glass; he creates several scenes and then fuses them together into a single block. it’s a really cool effect; i wouldn’t quite call his 3d, but there is a cool depth effect.

I decided to get myself a little harbor-freight sandblasting cabinet.
It took me a little time to get it put together properly, fix the stuff harbor freight did wrong, caulk it up, let it dry, repaint to cover the caulking, and allow to dry again (it’s been damp round here). Then I wrapped it in leftover automotive vinyl, partly to help seal it up even more, but mainly because I had this section of leftover automotive vinyl that was never gonna go anywhere but the trash.
The first glass I tried to blast was a learning experience. I went way too deep. The second one I did came out much better, but I was still having a few issues with overpowering the resist in areas.
Next I tried dialing down the power. Worked out all right.
I’m gonna need to make a light box to shoot these things, they get reflections from every direction. I tried to make that work to my advantage as I attempted doing a friend’s logos, but I was getting sleepy; it was a long day.
He was stoked on it, and some of his clients and fans have already been asking if they can buy them. So that is promising.
I’m still waiting on some actual sandblast resist to be delivered, so far I have just been using paint mask and sign-vinyl. The paint mask works ok for the glass where you don’t hit it with the blast media for very long at all. Address plaques are the only thing I had ever made sandblast-resists for in the past, so I tried making a board from some scrap white-pine offcuts, glued it up, and laid a paint mask stencil. White pine is not the correct material at all for a sandblasted sign, but for a practice exercise I figured it wouldn’t hurt to be able to totally ruin it and not feel bad. Had overspray on it already, so I figured I would go with a ‘weathered’ look.
I was able to get some depth before the resist was destroyed. The 70-grit black aluminum oxide blast media discolored my unsealed pine pretty badly, almost like black paint pigment (hmmm) so I washed the front with water and gojo, and it warped like I should have expected. Then I washed the back, let it dry overnight, and came back to find it pretty darned flat. So I painted in the letters, and cut an ‘oval’ with the jigsaw (poorly, geez, make a jig already) and hung it. 1st try out of the way.
Second try with wood I laid a double layer of the paint mask stencil on a solid piece of pine, and that worked a little better… but really I should be using cedar with sandblast-resist. Cleaned it, painted the whole thing black, and then came back with some silver.
Cool, now I have a little matched set to send to my buddy.
Then, after all that, I went online and looked up how to sandblast for the first time.

Oh, I am so envious. I have always wanted to try glass carving with a sandblaster. Your debut pieces are just marvelous!

A light box won’t make it any easier, you’ll just have a reflection of the light box itself (ie: more diffused reflections) in the glass.
Try a polarizer lens filter.

Very nice! How long did it take to weed each of those glasses before you blasted them?

I wasn’t timing myself, but maybe 1-2 minutes each for the Tamalpais Productions and Essential Extracts. About 5 seconds for the EA and 10-15 seconds for my little dude.
Because of how degraded the masks have been, I think it takes longer to remove after blasting than to weed in the first place.
Clean vectors make a world of difference.

What, and use my real camera?!
No, you are quite right. Although with a box of sorts as well I can control what is being reflected to a certain point.
Funny, now that you mention it, the last time I went to a 3D movie I kept the glasses and broke the lenses out to have a pair of filters for my phone.
I wonder what I did with them?

I have seen some incredible work done with different aggregate sized blast media, enables shading.
Not like it’s that easy to replace the sand and graduate, just sayin’.
70 Grit looks as rough as I would envision. Nice addition to the arsenal!
Absolute cleaning is a welcome ability. You will find it very useful. Careful with thin metal, you can distort it easily.

Tempered glass is another thing. You don’t cut tempered glass, good chance it will explode. Most of the strength of tempered glass is the surface tension. You can blast both sides of tempered glass and crumble it in your hands.

You dont have to use a polarized lens filter with an actual camera, you can hold it up over the phone optics just as well.
Do you have any polarized sunglasses? Aside from the added tinting, it will work the same way.
Just hold the lens/filter in front of the phone’s camera and rotate the lens until you get the desired affect.
With a piece of round glass, you’ll never be able to kill 100% of the glare because just a tiny sliver will align perfectly with the pattern in the polarizer and make its way through, but it will be a huge improvement.
With a flat piece of glass, say you’re outside of a building and want to photograph through a window to the inside, a polarizer will kill all the glare reflecting off the window and make it appear like it’s not even there!

Here we go, iPhone camera plus a Canon polarizer, pretty good difference between the two. The filter even killed the little bit of glare on the LCD screen in the background, and the glass jar in the background too.

Really nice sand blasting cabinet once you fixed it up.
You may also find a finer grit blasting material works better on glass. I love blasting designs into glass and it looks like you’re off to a great start in this area as well.
