Using Nitric Acid to Determine Metal Help?!?
Posted: Fri Sep 07, 2012 10:37 pm
So I got a new batch of rings (I know, I just stopped pricing down the last lot). None the less I used 10K nitric acid solution on a old school class ring. It turned blood red with marginal white whispy smoke . There are no markings of merit, anyone know what kind of metals will yeild these results?
Thanks so much.
