Mike, I think what you are seeing is the crystalline structure of the drawn wire.
The "as received" is generally in the hard drawn state. Take a new sample of wire and heat it read hot and quench in DW. That will anneal it and it will be very soft. Make several runs and then look at it under you microscope. Mike Monett wrote: > I looked at the darker electrodes under a 40X zoom microscope, and > noticed something funny.
