Messed around a bit playing with some glass tiles from Home Depot. They’re backed with a painted coating that I expected would ablate and leave the scored glass. I was interested in what kind of etching I could get with the glass.
Instead of ablating the paint it seemed to melt it into the etch. The view of the back was one I ran at 225 lpi for the etch at 1% power. I saw some striations in the black so bumped it to 5% and 340 lpi for the rest of the experiments.
Here’s the back of the 1%/225 version.
The last one is a close up of the front etch. I filled the etch with a paint pen and rubbed it off with a paper towel. I etched that through a wet paper towel as my “mask”. This stuff is .325" thick glass so probably didn’t need the paper towel but I do that with glass to keep it from overheating at the laser beam. The focus on the camera was so good it showed the pattern on the towel even when wet!
The face etch shows the shadow effect that comes from face etching acrylic too. It’s a bit distracting and does not add to the effect (personal aesthetic sense).
Oh, the “bacon” in the long tile was Comic Papyrus just for @henryhbk
Still on the bed of the Glowforge are two projects. One is a living hinge eyeglass case from Obrary and the other is the Aztec Sunstone from @marmak3261’s Mexican holiday. I made one in my big laser so I wanted to see how the detail compared. It’s serving as a coaster in my office so I’ll post side by sides tomorrow. This one is very nice (Proofgrade maple ply at medium dark engrave).
