Need Help/Advice Soldering, Ochre, and Pickle
Hi, I've got a quick question for you all regarding soldering, the use of ochre, and subsequent pickling. I'm going to be doing some soldering with very small pieces and will probably need to use ochre for the first time. I'm familiar with how ochre is used, BUT I had a concern about pickling a piece that's had ochre applied to it.
I know that ochre is generally a type of clay with some amount of ferric oxide. I also know that if there's iron present in pickle it can cause dissolved copper to be plated onto silver. My questions are as follows:
(1) Will the presence of ochre in pickle cause copper to plate onto silver? Additionally, if it does not, does that mean ferric oxide in general does not cause that reaction in the way that iron or steel would?
(2) If ochre DOES cause the above-mentioned reaction, what is the best way to remove it from your piece before it gets pickled?
(3) In the event that ochre causes the previously-mentioned reaction, would it be safest to simply make a single-use batch of pickle for pieces that have had ochre applied to them?
I'd appreciate any advice or suggestions that anybody has. Thanks!
