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

Works great I don’t have problems using it on 304 stainless steel and entry level diode laser. Very durable, needs good sanding to be removed It fuses great with the materials don’t need to use much of this spray Expensive? Yes! Does it work good with entry level 6000mw diode laser Yes! I recommend this product.

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...

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.

Product works great but is pricey.

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

Washed off. Did not stay black like it was supposed to. Seller was very responsive and contacted me, walking me through to get the desired results. Have to find the right settings. My test was on a keychain instead of a flask because it’s less expensive if it messes up. Used 50% power 5 speed 300 lines. Great black color however the metal was so thin, it bent. Make sure to test to find the right settings.

Yeah you pay big bucks for this stuff. But the amount of time it saves you when you can get it nailed the first time you try is worth every penny

This spray does work but getting your laser settings (power & speed) might take quite a few tries. My 60W diode seems to do OK at first test with 50% power and 1,000 mm/s but more testing will be needed. Also be prepared for some mess as what comes out of the spray is actually a super-fine white powder and prone to coming off with any contact and, if you're not careful, getting everywhere. I still haven't had the opportunity to determine how durable the resultant black marking really is. Will it survive on a brass tag on a keychain in my pocket, for example?

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!

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

Super fast shipping and received in good condition. Durable, permanent and high contrast. thank you!
