Because of its mercury content, cinnabar can be toxic to human beings. Overexposure to mercury, mercurialism, was seen as an occupational disease to the ancient Romans.
Why is cinnabar toxic?
Heating cinnabar results in release of mercury vapor, which in turn can produce toxicity similar to inhalation of these vapors. The doses of cinnabar required to produce neurotoxicity are thousands 1000 times higher than methyl mercury. Following long-term use of cinnabar, renal dysfunction may occur.
Is raw cinnabar dangerous?

Where can cinnabar be found?
Cinnabar, mercury sulfide (HgS), the chief ore mineral of mercury. It is commonly encountered with pyrite, marcasite, and stibnite in veins near recent volcanic rocks and in hot-springs deposits. The most important deposit is at Almadén, Spain, where it has been mined for 2,000 years.
Is Vermilion toxic?

How do you get mercury from cinnabar?
Most mercury forms in a sulfide ore called cinnabar, but mercury is also frequently found in small amounts in other ores. A common method for separating mercury from cinnabar is to crush the ore and then heat it in a furnace in order to vaporize the mercury. This vapor is then condensed into liquid mercury form.
