Blacksmithing - Ferric Chloride For Etching More Than Just Damascus 

You’re very welcome sir. Always glad to help.

Thanks much

You’re very welcome, sir.

Thank you sir. Both wax on and wax off can be equally aggravating when it doesn’t run in the right direction and coat the steel the way you want it to.

Excellent! I like helping folks.

Thank you very much

That should do it. If you want it even darker a few hours in a strong instant coffee solution should work

No idea. I’ve never tried it on stainless.

It’s used to etch circuit boards also.

I’d say it depends on what equipment you’re using.

@@serendipityforge333 Hi. I have a laboratory power supply with alligator clips and cotton buds, table salt and demineralized water. The logo I try to etch is small, about 25 mm x 15 mm. I want to achieve about 0,3-0,5 mm depth. The resist is vinyl (Oracal) but I am thinking to also try toner from my laser printer.

I’ve experimented with vinyl resists and using batteries as a power supply. It worked fine for me, it was just not something I enjoyed. Just keep everything insulated and don’t make yourself part of the circuit and you’ll be fine. Remember to keep your amperage low because it’s amperage that kills.

@@serendipityforge333 Thank you for your reply. I was concerned about the gas release...like chlorine or hydrogen.

@@BlueLineofthesky I always do any kind of etching in a well ventilated area.
