Brilliance Laser Inks Black Aerosol Spray

Works amazingly well - I’m using a 455nm 40W laser to mark copper. Without the paint, I couldn’t get anything but a faintly discernible mark after 5 passes at 1mm/sec, 100% power. Now getting superb marking at 100% power, 100mm/sec speed, off a single pass. Wish I’d discovered this earlier.

I did not expect these results. Just awesome. Technically I renewed (personalized) my tumbler. Shake well the can. Spray on the surface. Let it dry. (Do not touch it, it's like a powder). Laser engrave it. Wash with water. Ready! I liked this over a more expensive version as the plunger top is nicer and there is more information provided by this company... amazing customer service, they really went out of their way to help me get the right settings on my laser. Definitely will buy more!

This stuff works great! I have a 20w blue diode laser (Wecreat Vision) and initially purchased it to engrave stainless tumblers. For that, it works perfectly, however, on a whim I tried it on glass and was pleasantly surprised just how well it works! As others note, it doesn't engrave in black as with the stainless, but it etches the glass and leaves a very nice frosted effect on clear glass plates, drinking glasses and even Pyrex baking pans. As a note, I am using 100% power at 50 mm/s speed. I will be purchasing more...

Is expensive but don't use much product when lasering so would last for a fair while

It's expensive but it works. I use it in my laser engraving workshop and produces good results with my CO2 laser
