Copper metal that is required to maintain its color may be treated with an organic coating. Single-strand copper wire for electrical purposes does not usually tarnish enough to warrant special treatment. However, fine, multistranded copper wire is usually wrapped with layers of insulating materials. If the wire is kept wrapped, oxidation is quite low, and its color is maintained.
Put the wings in a single layer on the grill over the heat. Cook the wings for about 20-25 minutes total. Start by leaving them on there, lid closed, for a few minutes. Then use big tongs to have look underneath them all.
Flip after 20 minutes. Depending on the size of the wings they'll be done after 35-40 minutes total cook time. I throw them immediately into the sauce and toss, pull the plate setter out and open up the vents. Then toss them back on just briefly on each side to char the sauce.
