Has anyone tried the Norton method of tile “etching” in the glowforge? Every example I’ve seen has been done with a low power diode laser. It’s rather interesting if you’ve never heard of it. I’ll summarize as best I can.
Take a white ceramic tile… Spray it with a couple layers of flat white spray paint. Laser the hell out of it with your pew pew machine… then use turpentine or other agent to remove all of the white paint remaining.
What remains is a black (or grey depending on power used) “etch” of the design you lasered. And it’s not coming off. I’ve seen people take paint scrapers to it and it really does seem very durable.
I think they are getting basically the same sort of thing that cermark does with steel. It’s a chemical reaction to the laser’s heat that bonds it somehow to the ceramic (glass works as well) creating a permanent marking.
Just wondering if anyone else has tried it. I threw caution to the wind and tried it with a design earlier and while it appears to have left a very light grey mark, it’s nothing I’d care to write home about. I should have done a test tile with a bunch of different settings first, but I am an impetuous youth and don’t have time for that.
Tomorrow I shall probably try that whole test thing to see if I had too many pew pews (50) or too many vroom vrooms (750) or… perhaps not enough of either. WHO KNOWS!?
Here’s an example someone did with the technique and a diode laser.
