Zinc Plating At Home Safe Ways To Etch At Home For Printmaking?

Safe ways to etch at home for printmaking? - zinc plating at home

I've heard about some safe ways to burn without a plate using acid. I wonder if there's no way I could have back home, with no exhaust fans or health problems that can compete with, I no problem recording anything at night or during a period of several days. I'm more on the way to do this safely at home, I am struck with the etching rate. For example, I heard someone with tap water (do not know if it's true) ... Just curious, if someone tries something. I am a safety freak, so I want to secure something that is super. I tend to use zinc plates, but I have no problem with copper, if necessary.
