Brilliance Laser Inks 12 Oz Laser Marking Spray - Copper Tone Red, Permanent High Contrast Metal Engraving Aerosol for Fiber, YAG, Diode, and CO2 Laser Engraver Machine, BLI201

This works very good on metal my laser is the 10 Watt it works really really well

Seriously—don’t try to laser without this! I searched high and low, watched countless YouTube videos, read all the comments… and still saw so many people struggling to get their engraving right. (In my case, specifically with the WEcreat laser.) This product solved it for me! I even went back and told others about it. If you're stuck trying to get clean, precise engravings—this is the missing piece.

Worked as advertised.

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.

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...

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!

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.
