I recently purchased my first laser. I'm interested in adding color to my engravings. Specifically I want white text engraved on black metal. However I've searched online and can't find any white marking materials.

Maybe it's hard to make white ink that plays well with lasers?

I've had good success with paint filling (painting then sanding the surface) but it's much more work

Gotta be - black absorbs light so heats and fuses well I imagine
