How do I tell if my copper wire actually qualifies as Bare Bright before I sell it?
Short answer: Check three things: gauge (Bare Bright is generally thicker-gauge wire, not fine strand), surface (no oxidation, discolouration, or coating at all), and shape (it needs to be wire, not tubing, sheet, or bus bar). If any of those don't hold, it will likely grade as #1 copper instead — still a good grade, just a step down in price.

Thin, fine-strand wire — the kind found in some electronics or thin appliance cords — oxidises quickly once stripped and rarely stays bright long enough to grade as Bare Bright. Thicker single-strand or heavy multi-strand wire holds its shine longer and is far more likely to qualify.
The surface test
Bare Bright means genuinely bright, uncoated copper with zero visible oxidation, tarnish, or residue. Even a light greenish or brownish tint anywhere on the strand is usually enough for a buyer to downgrade the whole batch to #1.
The shape test
Bare Bright is specifically a wire grade at most yards — clean copper tubing, bus bar, or sheet, even if genuinely bright and unalloyed, typically still grades as #1 simply because of its shape.
