Darkening infi

This is the stuff that I use to etch a logo. I put a few drops on the logo of a coated blade , leave it for 30 minutes. Rinse and repeat about 5-10 times. Gives a nice deep etch. Then I would strip the blade. But the etched logo wasn’t darkened?

So you etched it with the coating on by just applying the FC to the logo drops at a time? But when you stripped it, the logo was not etched?
How long did you let the logo sit with FC ?
 
Yes the logo was etched. I let it sit for hours. But I rinsed and re-applied every 30 min. Like on your TGLB. The logo is etched. But it’s not darker.
 
The FC eats away at the steel. But it doesn’t eat the coating. So the logo ends up deep in the steel instead of just laser etched on the surface.
 
Just make sure you wash it with dawn first because any oil on the blade from your hands will resist the acid. It’s hardened steel, it’ll darken. Might take a few applications (because some washes off when you neutralize it with the baking soda), but it’ll get there if you keep at it.

At the very least it won’t be shiny anymore. There’s LOTS of tutorials on YouTube on how to git r dun, and they will be a lot more descriptive than I can remember right now. Just look a few up and let er rip.

I'm gonna do a little experiment while I'm at it. Is it going to get grey or black?

Never done INFI so I’m not sure. I was able to get VG10 (I think… it’s been a while) pretty damn dark. All else fails you can always go with that dark gun blue that JohnTheTexican JohnTheTexican mentioned (Kleen-Bore Black Magic) on top of what the ferric chloride does. That should getcha there for sure.

Knives Plus in Amarillo does a lot of acid stonewashed custom stuff on stainless blades and they come out plenty dark. No idea what their process is though.
