grsjax Posted November 28, 2014 Share #1 Posted November 28, 2014 While doing some research on photo etching I ran across this item. It is about making printed circuit boards but the etching part is what is most interesting. The etchant is a mixture of plain white vinegar and 3% hydrogen peroxide with a little table salt. Much less toxic/dangerous than the typical hydrochloric acid or ferric chloride etchant. I have not tried this yet but it looks like a good method. http://quinndunki.com/blondihacks/?p=835 dgbot, mtaylor and captainbob 3 Quote Link to comment Share on other sites More sharing options...
