i find this so interesting. I used to work in a pre-press graphics shop. We used nitric acid and photoresistant film. I never knew, and am now amazed at how this can be done with kitchen ingredients such as venegar and salt. Nice vid. thanks for sharing. Also, i'd assume this could be done without electricity, yet would take considerably longer. Have you tried that, and if so how long would it take?
Just to make sure - and I may just be being paranoid - that that was an aluminum plate, correct? I've got an intake plenum that I'd like to etch (aluminum) and this would be perfect for a custom logo.

This is super, super cool! Would this potentially work on a knife blade?
If it's aluminum yes
@@lukemitchell8182 Thank you!
Did you set a current limit on your power supply as well ? How much current would you say is flowing through ?
current was 1amp.
What's the rate of deepening?
I like that the etching gave it a black ending. What battery size did you use and was this salt water? What was the amounts
i think it was about a tablespoon of salt to a cup of vinegar, and I used 9 volts off my bench power supply.
correction: looks like i used 2 or 3 tablespoons of vinegar and a tablespoon of salt.

Yes. It was a Hammond-style aluminum enclosure.
How long does the etching last?
forever
