Heating cinnabar reaction
WebThe reaction usually appears as an inflamed red rash or may sometimes be scaly and flaky ( exfoliative dermatitis ). Red tattoo pigments cause the most reactions, particularly those made from mercury sulfide (cinnabar). Hypersensitivity reactions to pigments used to make black, blue, purple and green tattoos are much less common. http://www.chemistryexplained.com/elements/L-P/Mercury.html

WebExtraction of Mercury: Cinnabar (HgS) is first heated in plenty of air, so that it can undergo roasting. This turns HgS [mercury sulphide or cinnabar] into HgO (mercury oxide), by liberation of sulphur dioxide. 2HgS + 3O2 ⇨ 2HgO + 2SO2 Mercury oxide so obtained is again heated strongly in limited supply of air, so that it can undergo calcination.
