Laser on borosilicate

First try marking on glass with the laser using CRC Dry molly lube. Speed set as shown in the pic, 100% power, 2 passes because I haven’t figured out how to get one pass to work. Pretty sure the 2nd pass is a waste of time. Doesn’t seem to matter how much spray I put on, even when I can see thru it easily!

The last one did not seem 80x faster than the first so I need to investigate that. But it is marking very nicely.

Denatured alcohol takes off the moly spray nicely.

I can’t scrape off the marks with a steel tool.
