Brilliance Laser Inks 12 Oz Laser Marking Spray - Black, Permanent High Contrast Metal Marker Aerosol for Fiber, YAG, Diode, and CO2 Laser Engraver Machine, BLI101

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...

Brilliance Laser Inks marking spray has become my go-to solution for permanent part identification in the shop. I use it primarily on my aluminum milled parts, and it produces clean, sharp, high-contrast marks that hold up well in handling. I’ve also used it on some of my cutting tools and collets for quick identification, and it adheres reliably there as well. Paired with a 40W diode laser, the results have been very consistent once dialed in, making it a practical, dependable option for anyone needing durable, professional-looking laser marks.

It worked amazing. It made the engraving stand out much better. Will order again.

Product works great but is pricey.

Super easy to use and makes my engraving very dark! Dries pretty quickly as well. Highly recommend this stuff.

It works as advertised, in my experience; allows laser engraving on metals - chrome, aluminum, etc

Consistent quality

I bought this marking spray to write names on an 0.02in thick aluminum plate with a gold paint on top using a 40W diode laser. For the first 2 rounds I didn't get the expected results as I was high higher power and speed settings. The name will come out pale gray/white in color similar to the native Aluminum. I posted a question on the Amazon website and their customer service immediately reached out to me. Their customer service rep accommodated my schedule and called me in the evening. He provided some ideas on how to use the spray and also suggested that I create material test array using power and speed conditions of 10 - 60 for each settings. I applied the spray and used these conditions. The results immediately showed that I had to go down even slower in both power and speed to get the desired results. I ended up using a slower speed of 5 mm/s and power setting of 5% that allowed the marking spray to interact with Aluminum giving me beautifully engraved names. Excellent customer support and product. Highly recommend for any laser aficionados out there looking to engrave metals.
