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.
