is it just based on the dull layer of rust?

also how does and why does wire thickness come into play? like does really thin strands of wire have to be put with the number 2 even though it is bare and bright?

also what about pipes? does it have to be shiny brand new to be put in with number 1?



what about dull pipe that has solder and other contaminants compared to dull pipe that is just plain copper?
