I was cleaning up the shop today to try and get a "clean" start on the new year. Part way through my cleaning I discovered a box of equipment / supplies I had accumulated last summer when I was planning to explore metal etching. That discovery ended the clean up effort and launched me on a mission to etch metal. Ultimately I plan to attempt a cloisonne / champleve / gullioche hybrid. But baby steps first. I need to actually prove I can eat controlled cavities / holes in metal with acid.
As I was taking a break from designing my masterpiece on the computer, I stumbled across the following information on etching with a "renewable" alternative to ferric chloride. It would be great to not have to deal with disposal of toxic waste. Thought it might be of interest to others here:
Etching with Air Regenerated Acid Cupric Chloride
I don't recall Brad having mentioned this alternative in his experiments. Then again, there are a more and more things I don't recall with each passing day. So, I'll apologize in advance if this is old news. I intend to do a side by side comparison of copper and iron chloride etching and see for myself (unless somebody replies to this post with a definitive "don't bother, it won't work"). I'll report back on any positive results that may be realized.
