ISO: IDEAS, SUGGESTIONS, TIPS & TRICKS, NEED HELP T.I.A 😁

Specially sand painting. If I made some sand painting now, would it still exist 300 years from now if left on the ground untouched and with no wind? Would it need to be in an environment like a cave to keep it safe?

I am experimenting with sand art over the summer as something to do inside out of the hot Texas sun. I've started messing with the sandfall / sandcape frames. I glue 2 panes of glass together with aquarium adhesive and space them 2 mm apart with some wooden spacers I cut. After the sand is deposited to cover the bottom half of the frames, I fill it with an 80% glycerin - water mixture with a bit of shampoo to try to promote bubbles (that doesn't work so well for bubbles but after I get the sand sorted I'll work more on the liquid mixture).

I've been collecting sand samples from where ever I can find, seeing how different ones act between the panes. I've surely learned a lot about sand in the past couple weeks. River and beach sand so far seemed to have work allright, I'm pretty sure it's because the grains are the most spherical. I haven't gotten any desert wind blown sand but I think that will work well. I get layering by density but it doesn't fall too well, I think it's because the sand I've gotten so far has been pretty fine, like 100-120 mesh. I have some silica sand coming that's 70 mesh to see how that comes out.

Is there anyone else with experience in making these? Am I on the right track? I want to be able to make some nice wall hangers but so far they haven't turned out how I like. The grains fall and kinda flatten out into layers of color depending on the sand type, but rarely get any of the mountain shapes like I see in the ones for sale online.

any insight on getting some of the kinks worked out would be greatly appreciated.
