I came across the idea of red mercury, and mostly got hoax videos or lots of mainstream sources claiming it to be nonsense. The only dig into the true origins of this meme was this short article I found from this source: https://www.nti.org/analysis/articles/red-mercury-lithium-6-russian-weaponsmiths-say/ > Abstract: >The name 'red mercury' is a code word used in the USSR nuclear weapons program since the 1950s to describe enriched lithium-6. Lithium-6 has two nuclear weapons uses: as a reactor target for production of tritium, and in the form of lithium-6 deuteride as a thermonuclear weapon material. The most common production process uses large amounts of mercury as chemical agents. The code name originated because mercuric impurities contaminate the lithium- 6 during production, giving it a red color. 'Red mercury' has been identified by many European media reports as 'any of several simple mercuric compounds and tinctures offered for sale by Russian and European agents,' but none of these had any nuclear value. The uses for lithium-6 are consistent with claims about the uses of 'red mercury.' The USSR built a large complex in the early days of their nuclear weapon program to produce and stockpile lithium- 6. Some was also supplied to China in the 1950s. Russian and Western officials have both stated that no lithium-6 from Russian or Chinese inventories has been diverted since the disintegration of the USSR. >Abstract Number: 19930690 Headline: 'Red Mercury' is Lithium-6, Russian Weaponsmiths Say Date: 22 July 1993 Bibliography: Nucleonics Week, p. 10 Material: 'red mercury'
