Selective etching of silver on copper

Hi,

I am looking for a selective etchant for silver in presence of copper. I would like to reveal the structure of a silver layer electrodeposited on brass and could not do this with the traditional etchants, because they attack copper much faster...

Thanks

Virginia

Try kaker.com website-they have very good online etchant database. Metallography and microstructure of ancient and modern metals book (by D.A.Scott) may help you too. Hope it helps and good luck!
