Using metal marking on WOOD?

I am experimenting with trying to get blacker blacks on Bamboo, and am having a lot of luck using Brilliance Laser marking spray…
here are some pics:

Washed

Dried then sanded

Isn’t that stuff fairly expensive? How’s this an improvement over using masking and something like a black spray paint?

Experiment FTW!
That was some of the most fun I had when the company gifted me with a pre-release machine, trying different materials - a treasure hunt. :sunglasses:

Very interesting! I wonder how it compares to the baking soda hack?

Please tell more! - I never heard of that one!

That’s pretty impressive. I like the detail that can be achieved, plus it is so easy. Thanks for the video.

Videos are annoying, so save yourself the 4 minutes of pointless talk:

Description:

Using a baking soda and water mix to darken your wood engraving. Helps achieve a darker, more detailed result with less power. Prep… on birch, lightly sand, spray solution, let dry and boom… engrave.

They’re using about 1 tablespoon of baking soda to two cups of water. It comes out a bit darker for the same settings.

Possibly relevant comment:

I’m just getting into lasers. But for the last year I’ve been doing fractal wood burning in which I use a solution of 1 tbs baking soda to 1 cup of water. The baking soda / water solution stains the wood. Then I use osilic acid to remove the stain from the wood. I’m thinking that is why your engraving is coming out darker.

Wow, impressive!

Yep, like the video says, it’s just baking soda and water. The mixture alone can yellow some wood, but I’ve seen people add a little borax to prevent it. I’ve only played with straight baking soda and water once or twice, and it really does make for a darker result. And it’s whole hellofalot cheaper than the spray. :stuck_out_tongue:

Food safe?

the metal marking material is food safe, and I coat the board with poly,
the flip side is really used for food prep, the lasered side is more for display
its usually a good idea NOT to cut food on the lasered side, food particles can get trapped in the grooves and rot and cause bacteria.

And I’m in SJC, so you’re also YOLND! (You Only Live Next Door :laughing: And I totally understand no one will know what county SJC stands for other than maybe you.)

I wonder if I let it do a first engrave, then pour the baking soda mix in the indent, let dry overnight and give it a second pass with the laser.
Hmmmmmmmm

Do it. Take before and after pics!

OF COURSE!!!
I do!
