As mercury - the only metal that is liquid at room temperature - is also highly poisonous, mining it in its liquid state would be extremely hazardous, Fortunately, its found in the earth's crust in the form of solid mineral ore - most commonly cinnabar, a soft reddish-brown deposit. To extract the metal, the ore is heated, releasing mercury vapour that is passed through a series of tubes to condense it into the silvery-white liquid found in thermometers.
