Two examples from the zinc smelting industry Let it be supposed, in the first place, that there are three phases present, namely, zinc oxide and carbon as immiscible solids, and a vapour phase consisting of CO, CO2 and zinc vapour. (The possibility of forming liquid zinc as a fourth phase will be discussed later.) The system would therefore be divariant if it were an entirely arbitrary mixture ...

Zinc - Encyclopedia
ZINC, a metallic chemical element; its symbol is Zn, and atomic weight 65.37 (0= 16). Zinc as a component of brass (XaXKOs, 6pei-XaXKos) had currency in metallurgy long before it became known as an individual metal. Aristotle refers to brass as the "metal of the Mosynoeci," 2 which is produced as a bright and light-coloured XaXK6s, not by addition of tin, but by fusing up with an earth.
