Multi-Etch: The Non-Acid Etching Alternative for Titanium and Other Metals

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 mokumé and the crystals in meteorites by etching the different metals at different rates, thus slightly raising one over another.

Here is some meteorite showing before and after treatment with Multi-Etch:
