Cooked wire

I am sure someone will come along with more info but it seems to me that the copper wire has a coating put on it during the manufacturing process to ward off corrosion. The overheating of the wire causes this coating to be burned off as well as copper(II) chloride to be burned out of the copper itself making it brittle. The green tint you are seeing is corrosion starting to form. I too prefer to strip the wire back into fresh copper as a repair, if fresh copper cannot be found then the wire is replaced.
