I’d like to thank Bill at Reactive Metals Studio, Inc., for
inventing the hydrogen peroxide pickle. It’s not as fast as my
beloved nitric acid (at getting rid of cuprous oxide) but it’s
something I can use in teaching about bright-dipping in my adult
ed. jewelrymaking classes AND my students can make it up at home
(rather than having to try to find where to get nitric acid…).
Thanks, Bill! Judy Bjorkman
