I took two samples with me to ask about them. Didn't want to throw them in together if that devalued any of it. I had wire that was in a loose V shape from the coil in the back of a TV. It was reddish in colour. The other bit was off a circuit board that I pulled off and rolled a few small bits into a ball. He said it was coated in something and both were Brazier, the same as if I'd burned the plastic off wire. He also said the thickish cable in the back of TV's would be the same. I assumed that would be bright, like a smaller version of a welding cable.
