Steve K Posted October 15, 2008 Share Posted October 15, 2008 I use two different ones. One is seven parts muratic acid to one part pcb echant. The other is pcb and water 50/50. The 50/50 mix will give a darker etch and the other lighter. Steve Quote Link to comment Share on other sites More sharing options...
JFsmith Posted October 16, 2008 Share Posted October 16, 2008 I use a mix of 2 parts hydrogen peroxide and one part muriatic acid. its yet another mix borrowed from the electronics guys. Quote Link to comment Share on other sites More sharing options...
kbaknife Posted October 16, 2008 Share Posted October 16, 2008 Not sure why you guys are mixing other "things" with FeCl.? Depending upon the depth of etch and the time necessary, the only thing needed to alter its effects are varying ratios of distilled H2O: Most common being 3:1, H2O:FeCl.

Max Mulholland - Tetnum Posted October 16, 2008 Share Posted October 16, 2008 the reasoning for the mixing is that feric-cloride is expensive and there is no need to use it and its cheaper to use mixes and make a diffrent mix depending on what kind of etch you want that time Quote Link to comment Share on other sites More sharing options...
wulfgar Posted October 17, 2008 Share Posted October 17, 2008 I'm still pretty new to blacksmithing and knife-making. Can someone kindly explain how the etching and use of chemicals work? Thank you. Quote Link to comment Share on other sites More sharing options...

Probably enough to last a life time of etching. By the time you dilute it with water you've got a 5 gallon bucket! It's not expensive.
