BRILLIANCE LASER INKS12 Oz Laser Marking Spray - Copper Tone Red, Permanent High Contrast Metal Engraving Aerosol for Fiber, YAG, Diode, and CO2 Laser Engraver Machine, BLI201

In the instructions to this product, both on the label and on the company's website, it is recommended only for CO2, fiber and YAG lasers, not for diode lasers. So I was trying it with my 10 watt xTool D1 diode laser purely as an experiment. To my surprise I found that it worked fine, and without having to use extremely low speeds at 100% power. Testing on a sheet of stainless steel, I started out with slow speeds at 100% power, and first increased the speed and then decreased the power. Interestingly, with this "copper tone" spray, the markings left by the laser came out black with my first tests. Only after increasing the speed and decreasing the power did I start to get something of a copper color. Apparently more laser power burns the pigment and/or binding agent and makes the designs dark. So if you want copper-colored designs with this product, there's actually a fairly narrow range of settings that will work for that. I can give you the figures that worked for my laser, but you'll have to experiment to get the best ones for yours.And the figures are:At 100% power, I got nice dark black marks at 1000 mm/minute and slower.3000 mm/minute at 75% power seemed to be about optimum for getting copper-colored marks.At 3000 mm/minute and 50% power the markings seemed to be fading a little.At 5000 mm/minute and 50% power the markings were definitely faded.It should be noted that products like this work by bonding a pigment onto the metal surface; they don't engrave or etch the surface. However, as long as the laser settings are good, the printed designs will not scrape off. To remove them requires aggressive sanding that removes a layer of the metal surface as well. My guess is that some kind of chemical bonding with the stainless steel is taking place.(Sorry I have no picture accompanying this review, but my test sheet ended up as a jumbled mess.)

I had purchased a few blank tumblers and a couple flasks to engrave. I had thought that I would just engrave "raw" until I received this product. Wow, it created such a warm, but stand out result! I am making Christmas/birthday presents with this set of tumblers and flasks, but I have been talking to a teacher friend of mine about creating some event awards for kids - the school systems in my area like to have an end of school day where all the kids participate in physical activities like running and stuff and of course they give out awards. Considering they are kids and do want the ribbon, we talked about a secondary award that they could use - a tumbler with the event and date engraved on it. So I have purchased several tumblers with this copper ink used to engrave the event and year, they will be receiving something they can drink from and remember their participation - too cool! Love this stuff and will be using it many, many more times!

This copper marking powder spray is really neat and the end results are unique, depending on surface applied too and setting used to burn can be from bright copper to dull red reminiscent of rust. Application is easy but once dry the marker powder can be wiped off very easily. Many variables to adjust to get different results but when you have your settings right the results are stunning.

I used this to laser engrave tumblers. It worked well at times but was not consistent. I use the black and have not had the same issues

I have an Xtool D1, and used my 10 watt laser head to mark these two knives in the photo. This spray is easy to apply and wipe off (almost too easy so you have to be careful when focusing your laser not to hit and remove). I’m not exactly sure why they don’t also market this to diode laser users because it does work.If you look at the difference in the color of the text on the knives, David has a slightly darker more copper color (and yes I know it’s at a different angle in the pic that makes it look even darker). Normally you do test runs to nail down the power and speed to get the best results, but I didn’t have sacrificial knives. In this case, David was done at a slightly faster speed and resulted in a better copper tone. I wanted to mention this so if you aren’t getting the results you want, try doing a test grid on a sacrificial item to get the best settings for your laser.One other thing to note, is that mine did come with an extra nozzle if one becomes clogged. Overall I like the spray, I just don’t like how crazy expensive it is.

This is an excellent product- It allows you to use your laser to mark Stainless, aluminum, and other metals that otherwise would be out of reach without a fiber laser.I used it with a 130w CO2 laser. I based my settings on the suggestions on the Brilliance laser inks web page, and adjusted them a bit as they were for a 100w machine. It worked perfectly the first time!The markings are crisp, clean, and VERY dark. The 'red' color is definitely more of a copper color, see the second photo (the close up) for an accurate representation of the actual color of the marking. It looks great on stainless.It's easy to use, too. Spray it on, then let it dry. It only takes a few minutes. Laser the piece, then wipe off the remaining spray. It's a powder once it dries, and it comes right off. That's all there is to it. The marking is VERY permanent- the only way i've found so far to remove it is to sand it off.It seems a bit pricey, but you don't use much so a spray can will go a LONG way. You'll be able to get a lot of work done with a single can.I can't wait to try this out on stainless tumblers.

I've used both the copper tone red and black laser marking spray and the color difference is insignificant. You're better off using the black spray and save yourself a few bucks. It might show up better on specific material but that wasn't the case for me.
