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...

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

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

I had mixed results using this product. My application required text and photo on a memorial plaque. I started with anodized aluminum sheet with a satin finish. (AKA Brush finish) The text transferred well, it was black and well defined. The image (B&W bit map) printed well, but due to the satin finish, directional lighting was critical to viewing the image. Depending on the viewing angle, the lenticular scratches reflected the light in such a way that the image appeared as a negative. Viewed from another angle, the image appeared as a positive. Realizing that the lenticular scratches were the problem, I sanded through the anodized finish with a random orbital sander. I sanded the aluminum down to a matt finish starting with 80 grit and ending with 1000 grit paper. After degreasing with rubbing alcohol, I ran several trials at different speed and power settings on my 30W Epilog laser. The matt finish did not produce the positive / negative issue of the satin finish. However, I had trouble with the fine matt finish not being able to reproduce the B&W tonal range of my image. In general, the image contrast was low. Overall it was either too light or too dark depending on my settings. I scrubbed the plates with the orbital sander to remove the image and text. After several trials, I discovered that the 1000 grit matt finish was too smooth. My best results were achieved with an 80-grit matt finish. The text always printed well regardless of finish, and I had reasonably good tonal range on the B&W image using 600 DPI, 75% Speed, 90% Power. (1200 DPI always printed dark and 400 DPI did not retain image details.) In conclusion, my best results were achieved when the aluminum had an 80-grit matt finish. Fingerprints are a problem. Degreasing is essential and avoid touching the engraving surface. The engraving was not as durable as I expected. It was very easy to scrub through and sand the image off for successive trials. I applied a clear lacquer finish to keep the aluminum from oxidizing. The finished product will be framed under glass.

If anyone is hesitant about ordering this based on price, don’t delay and order it! This product works better than I expected. I was nervous about spending the money because I’m new at layering, but I’m glad I did. Dry moly does the job, but based on everything I read, it can cause damage to your machine from the fumes. Also with dry moly, to mark stainless you have to go 5-10 passes to get image to show up and even that is inconsistent which takes up valuable time. With this spray I did two passes and images are super crisp and no dead spots(I did a test run and one pass works, image gets crisper with a second pass). The axe was done with dry moly for the image and Brilliant marking spray for the words. As you can see, the image done with dry moly looks a touch faded. That was after 5 passes, whereas 2nd Place was two passes with the Brilliant marking spray. I’m still getting the hang of doing even coats with the spray as going heavy causes it to have running with the spray, though it doesn’t affect the lasering process, it does waste product. This product is definitely worth the money. Hope this review helps other small business owners and/or people with their decision to buy.

I SWEAR by this stuff, when it comes to lasering. I use it for glossy white tile, stainless steel, brass and other metals and materials. Yeah, it says it's for CO2 lasers, but works great with diode lasers also. Just make sure you run a material test array to get the right setting. Doesn't take much. In fact, a super light spray one way (just enough to tell it's there), wait a few minutes for it to dry, and spray again. SUPER LIGHT COAT where you can almost see the original material. And go light on the power or you'll burn it back off if too high, or not do anything if too low.

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.

Product works great but is pricey.
