Bronze is Copper+Tin (Cu / Sn), Brass is Copper+Zinc (Cu / Zn). No Zinc
in Bronze. (memotrick: you got only one Z, either in component or in
Dezincified bronze seems a non-sense. It does exist for brass, nevertheless.
Pure copper is rich pink/orange, not deep red. Oxydized copper can be
green or blue. The usual green stains on outside statues are
copper-oxyde leaking from the bronze alloy.
Beware, both Bronze and Brass might be abbreviated Br inadvertently, but
usually Brass is Br, and Bronze Bz.
