Etching mokume with Multi-Etch®
I originally perfected Multi-Etch® for titanium production. It’s a nonacid (pH 6.8) alternative to hydrofluoric acid. I’ve also tested it on other metals with great results.
Multi-Etch® will enhance the patterns in mokume and the crystals in meteorites by etching the different metals at different rates, thus slightly raising one over another.
