Subject: Electrolysis / Light Purple Question
Hello,
We've been running electrolysis on some iron artifacts for the last couple of months, and this afternoon I ran into something I have not yet seen; there are spots of very clean looking light purple on all three artifacts being treated. I would suspect manganese from the sacrifice may be to blame, but we have been using it (with daily cleaning, of course) since the very beginning, and have never seen this before. Any thoughts?
Thanks,
