I just looked back at the setting I used for this tile:
This is a porcelain tile from Home Depot. They come 9 to a sheet.
I applied 2 coats of Rustoleum flat white paint about 20 minutes apart then let that dry for an hour or so.
Speed = 250
Power = 30
Convert to dots
LPI = 340
Scrub off the excess white paint using paint thinner.
Wow, that is fantastic!
how big is the tile?
Thank you for digging that up and sharing!
Wow! That looks 3D! Great job. I’ll have to make note of your settings. What was the original picture like?
I did. 
Really amazing,
Wow that is fantastic.
So… The tile is black?
white. The norton method burns the paint which fuses to the tile.
And it’s the most durable marking I’ve seen. I took the corner of a paint scraper to one that I did and really tried to scrape it off with only a slight marring of the surface. And that wiped away with very light cleaning.
Awesome! Thanks for the technique.
The detail on that is just bonkers. I need to play with that!
No the tile is white and you paint it flat white before lasering. Some chemical reaction creates the dark areas.
Lord, I barely understand this. So you prep it with spray paint and then run it using dots?
Either way, amazing.
just plain wow.
That is correct. Regular white porcelain tile sprayed with flat white paint. After the engraving it will look rather dull until you remove the residual paint with paint thinner.
Amazing! One of the best things I’ve seen done with the Glowforge!
