As an alloy constituent, however, zinc was in use well before that time. Brass, an alloy of copper and zinc, was produced by the Romans as early as 200 bce by heating copper, zinc oxide (ZnO), and carbon together. The zinc formed by the reduction of its oxide was absorbed into the copper and did not appear as a separate phase.
