Hi there! Has anyone tried electro-etching Sterlium? I am interested in trying to etch it in a 6m solution of Cupric Nitrate which I have solely be using for 925 and fine silver. Is it possible that using Sterlium could contaminate my solution? I find it pretty impossible to get all the residue from the anode and cathode out of the solution after etching so guessing that remnants will be present. I tried finding info regarding what Sterlium is actually alloyed with but haven’t found anything really specific.
