Abstract
An etchant for and method of removing a glass coating on a metallic wire is provided. The etchant comprises an acid solution having metal ions contained therein. The metal ions prevent the acid solution from pitting or damaging the metallic wire, while allowing the acid solution to effectively etch and remove the glass coating. In one embodiment, a fluorine-based acid solution can be used. In another embodiment, a glass coated, metal alloy microwire is etched and the metal ions added to the etchant are chosen to be the same as the majority constituent element in the metal alloy. The glass coating can be either removed in full or only partially removed.
