They call them penny tiles, they’re about 0.75” in diameter, about .24” tall. Not sure what I’m going to do with them but I’ll think of something. I better, because they come as a sheet of 240 tiles!
I had a similar thought, a nice travel checkers/chess set is definitely an option. Almost perfect size for Go/Pente. They’re very slightly domed, they feel nice in your hand.
Sand them thinner and they’d make a really good 1/8" mixed media inlay centerpiece. @rbtdanforth works a lot in 1/4", he wouldn’t really have to do much to them at all.
They tear off easily, leaving a tiny bit of residue. A quick hit on 320 grain sandpaper removes the last of it. Like quick quick, 5 or 6 strokes. If I had to do 100 of them, I’d cut a jig to hold them in place and then run a hand sanding block right over it.
You might be able to remove it with a solvent if you preferred, but I just went mechanical.
I have no idea what that backing is made of… I wouldn’t want to find out it was unsafe to laser. I’d be more likely to cut a jig for engraving as a gang. I just did the one, so I cut a 0.75" circle out of baltic and slotted the tile in for engraving. Can’t beat the accuracy of a good jig.
Just soaking them in water may take care of softening up the adhesive used to adhere them to the mesh so you can wipe/scrape it off the back (if you don’t have other reason to sand down the back).
I have too many horror stories of working with tiles on mesh that the mesh and even the adhesive used absorbed moisture out of the thin set/mortar bed & so had a mess to work with to get tiles relaid to finish bath or kitchen projects in various homes over the years!)
