Insulated copper wire turned into gray powder

[QUOTE="Majorana, post: 6230528, member: 583529"] Okay, it is [I]theoretically[/I] possible that a length of wire is copper while another segment is/contains another metal, but I feel it's quite a remote possibility. Nevertheless, "impossible" and "unlikely" are entirely different concepts. At this point, I believe that the best action to take is to have the grayish powder analyzed. As I said before, while there are plenty of clinical analisys labs out there, finding a general chemistry (inorganic) analisys lab available to a private citizen is not so straightforward, at least where I live. I'm on the hunt anyway. [/QUOTE]
