Brilliance Laser Inks 2 Oz Aerosol Black Laser Marking Spray for High Contrast Metal Marks | Permanent and Durable Metals Ink for Fiber, YAG, Diode, and CO2 Laser Engraver

I was alarmed when I first tried this as I needed it to engrave sterling silver discs which resist normal lasers. The first time tried it on a test piece it just wiped off so I went back to the product details and following the suggested settings for the type of laser you have. I then resprayed and tried again and repeated it three times. Worked perfectly and proved resistant to cleaning and polishing, it took a black silicon wheel to remove it by resurfacing the whole disc. So it’s fine for silver and easy to use. Worth persevering!

Works great just seems expensive well it all seems expensive lol but works good you'll have to mask stuff off

I should have paid mor attention to the 'size'. $100 for a tiny tube size spray can - sorry thats a rip off.

I used this as a newbie to laser engraving. It worked really well. I am still experimenting but as a cheaper option, the small bottle is great when you are still learning.

Works great on glass for laser engraving.
