I’m still uninitiated, even though I have a few tiles sitting next to my GF…

That looks amazing! Well done!
Do you mask the tile for engraving ?
Do you mind sharing your settings used to create these pcs ?
Thanks in advance!

There is no need to mask the tile. Masking could be handy if you want to do multiple colors and use the mask for no-go areas. I used multiple colors on the ones I did without any masking, which is impressive for me as my coloring ability is rated at: eats paste in corner. But as for lasering, not required.
In regards to settings, read the first several posts of the thread that kicked this craze off:
As you’ll quickly see, a wide range of settings works. Also, multiple methods of removing the excess color. I use off-brand magic erasers.

I picked up a bunch of old woodcuts (some not PC) from some internet site way back when and tried out this one.

How did you do the coloring?

Sharpies! You don’t have to color inside the lines, either; just clean the messy stuff off with alcohol.

Exactly how it’s explaned here! 
So I was working on a stack of tile coasters with the logo of the practice where I work, and someone happened to mention that the new owners are changing the logo…
sigh
I guess I can cart them down to Portland and give them to our sister practice that’s staying under the previous owner.
The acrylic paints are there because I tried them for coloring (see the gold tile). Not as easy to clean up as Sharpie, but 000 steel wool does a good job.

I tried my first tile work tonite. Happy enough with the results. First, I used a phone app called Inkwork to convert a photo to more of a black and white line drawing. Once I had the image I liked, I think brought it into Inkscape to convert to a SVG file (Could have probably just brought it directly into Glowforge).
The tile was a basic white gloss tile from HD, roughly 5/16" deep (.312). I used full power and full speed (1000) and had setting set to convert to dots. Lines per inch was set to 195. Took about 12 minutes to burn the image.
It was a little difficult to see the effect at this stage, but I pushed forward.
Then, used a black whiteboard marker to wipe across the surface. this got the ink into the laser burned areas, but the glossy areas would still allow it to be wiped off.
Finally, just used a simple cloth wipe off with water to remove the excess ink. While I think I’d like the lines darker, overall a good effect.
My sense here is that a second pass might make the cuts a little deeper allowing more space for ink. I’d also be curious the effect of different inks to stain the tile as that might be useful. It looks like others have used certain colors to good effect. There is also prob a good final step in sealing the tile which Ive not done.

If we had only thought of the stock option when the original post was made. Lol

Dry erase markers actually use a grainy powder. I wonder if it might have shown up clearer with a Sharpie?
Off track: That’s why you can erase permanent marker from a smooth, nonporous service by scribbling over it with a dry erase marker and then erasing the scribbles. The fine powder acts like a polisher. (It’s how I got my daughter’s masterpiece off the regrigerator door…)

I’d like to find some white tiles for etching that are smooth-backed (not ridged). I’m having a heck of a time finding any that aren’t upwards of $3 a piece.
Anyone have a suggestion?
A $0.19 tile and a belt sander?
