what they call, nano nuclear : "* (2) 2HgO + H4Sb2O7 => Hg2Sb2O7 + H2O Whatever else it may be, mercuric pyro-antimoniate is clearly not a dream. As to the amalgam it produces when pressurized with mercury and an actinide within a neutron-rich environment, this supposedly being the means by which red mercury is produced, well, who knows?"

In many cultures, people learned to make mercury metal from its most important ore, cinnabar. When heated cinnabar releases mercury as a vapor (gas). The vapor is cooled and captured as liquid mercury. (no, what you have for kids injuries is not liquid mercury...)
