etching of pure copper

Posted by Julia Wiecken on May 12, 2008 at 06:51:43:

I am about to analyse some metallographic samples of pure copper.

The etchants I am using are:
120ml ethanol (C2H2OH)
30 ml hydrochloric acid (HCI)
10 g ferric chloride (FeCI3)
I was wondering in what the concentration the hydrochloric acid should be.

Thank you very much for your help,
