solid copper wire get stiff when old ?

[kwired]

I just held a magnet to it, no attraction. sanded its surface = copper color, and inside the cut solid bare wire is copper colored. Irs just night and day different than my modern solid bare copper in flexibility. Thanks.

It probably a piece of hard drawn copper.

Soft copper that got stiffer with age still probably bends easier than hard drawn copper.

Yes, the insulators were threaded onto a wooden dowel.

Used to find those glass insulators on the railroad tracks in my backyard when I was a kid. Old telegraph lines. I didn't know what they were back then but I collected them. They were a very thick green glass.

People sell them on EBay. Some of the odder colors can get pricey.
