hard to tell in pics, didja copper the ball? just re-flashed mine about a week ago.
1/2 cup vinegar, teaspoon salt, 1/4 teaspoon sugar.. microwave 45-60 seconds.
add a dozen really tarnished dull pennies to the soup for 3-4 minutes, then remove (use plastic for everything!)
then drop the (clean no oils or fingerprints) ball in and slowly roll it around about 4-5 minutes..
viola! it's been copper flash-plated..
very thin shorter exposure looking more gold, or repeat a couple times to take it to deeper copper, either way wax it afterwards will be slipperier and slower to tarnish, or if you hate it just rub it away in a few minutes with some automotive rubbing compound.
you can also put it over a gas stove burner a while using tongs can get some wild irridescents, or cook it hard and take it to black like a cannonball, just depends how long you roast it.
