Brass is not copper, but a mixture of copper and other metals mostly zinc.
Salt is a chloride not an oxide. Your mixture was a mix of copper, zinc,
sodium chloride and some other metals. The copper oxide you want is nearly
black. Burning the pure copper is the easiest way to get it. Excess heat
will flake it off.
