'''Zinc''', chemical symbol Zn, is a moderately reactive, bluish grayish metal that tarnishes in moist air and burns in air with a bright bluish-green flame, giving off fumes of zinc oxide. It reacts with acids, alkali's and other non-metals. If not completely pure, zinc reacts with dilute acids to release hydrogen. The one common oxidation state of zinc is +2. From 100 °C to 210 °C (212 °F to 410 °F) zinc metal is malleable and can easily be beaten into various shapes. Above 210 °C (410 °F), the metal becomes brittle and will be pulverized by beating. Zinc is nonmagnetic. In nonscientific text zinc is also referred to as "spelter." | '''Zinc''', chemical symbol Zn, is a moderately reactive, bluish grayish metal that tarnishes in moist air and burns in air with a bright bluish-green flame, giving off fumes of zinc oxide.

Zinc is used by the Covenant as a decorative material.[1] Silvery metals are rare for the Covenant, so they find human's liberal use of them strange.
