I use laser etched dichroic glass while glassblowing and was thinking that the glow forge could do this! I use Borosilicate glass (lab glass) which can be purchased with a coating that can be etched away or left.
Here is a example of a laser cut image before its encased in a marble
That looks absolutely amazing! From what I’ve read here, there’s not a consensus on whether or not a CO2 laser like Glowforge could do that - definitely something I’d like to test!
Boro is pretty sturdy stuff, so you are unlikely to shatter it.
Since you are already sandwiching it between layers of clear then I think your main concern would be bubbles where the laser etches the surface.
Of course as @aeva says, the best thing is to experiment!
OK, I need to revise my opinion of borosilicate!
Apparently it has such a low coefficient of thermal expansion that you really can’t etch into it with a CO2 laser (at these power levels anyway).
I have no idea what that means for the dichroic coating, so basically I am going to shut up now.
Yea 33COE for Boro, soft glass is between 90-120coe. From what Ive read I think the laser should have no problem etching the dichroic layer! Il do some more research
LOVE THIS! We have a stained glass warehouse in Boulder that has lots of dichroic stock. Can’t wait to pillage that place once GF comes in. I’m imagining making some seriously classy goods.
