How On Earth Did Ancient Civilisations Get MERCURY?

[@Chemistorian]

I'm getting a LOT of comments saying that other metals (e.g. caesium and gallium) are also liquids at room temperature. Apologies if this was unclear or misleading in the video, but in the scientific world, room temperature is commonly standardised at a temperature of 25°C. At this temperature, mercury is the only metallic element that's a liquid.

Unfortunately, Gallium isn't a lot of fun to play with. I had to warm my small bottle of gallium under a running hot tap to get it to liquefy. My hands weren't warm enough to do it, even after half an hour of hold the bottle tightly in my fist. Also, once you've got it liquefied, when you finally pour it back into the bottle, you are left with a grey dust in your hand (an oxide ?) so you are losing a fraction of your stock of Gallium each time you do this.

One of most used substances in ancient China was cinnabar. the Taoists were always heating and refining substances that they used. So it isn't a leap that they knew about liquid mercury.

Also as far as I know the emperor didn't drink mercury, he ate pills for longevity containing mercury. Maybe in the form of cinnabar.

[@TnT_F0X]

I picture the discovery of Mercury going something like this... Cinnibar looks awfully close to Iron Ore, so it was likely mistaken for it by ancient Iron producers. They burned the ore like they would to make Bog Iron... but instead of getting metal they found shiny droplets of mercury dripping from the walls and roof. They probably FTFO and came back later to collect the odd metal. They likely also died early from vapors refining the production... so The Leaders were like cool, and filled a tomb with it to kill robbers.

[@red.aries1444]

Qin Shi Huang used mercury as a kind of medicine and elixir of life. Even if the ancient leaders knowed, that mercury is poisonous, they would have known, that it doesn't kill immediately, so it doesn't make really sense to use it as a form of protection against grave robbers. But it doesn't evaporate as quickly as water and it doesn't drain easily into the ground. It's shiny, so it makes a perfect liquid in a model to represent rivers.

[@bromisovalum8417]

Actually drinking mercury metal is not as bad as you may think. Inhaling mercury vapor is what is dangerous. If you drink the metal you just pass it back out again after a few hours, as the metal is unaffected by stomach acid. This was confirmed by a German chemist, he drank 200 grams of mercury metal on one occasion in a self-experiment without harm. In the case of the emperor who was obsessed with mercury, it is likely through repeat exposure he inhaled the toxic levels of mercury, as again, the metal does not react with dilute hydrochloric acid (aka stomach acid).

Natron oil refers to natron soap with a 99% chance. Bolus of Mendes is widely consider main source for most of the anonymous writings referred to as Pseudo-Democritus. Mendes is about 30km from the Egyptian source of Natron (now called Wadi El Natrun). Egyptians at the time literally made soap from this Natron, it's also rather interesting soap because it has a rather high pH. The fact that these chemists ignored this is kinda weird.

The deadly part probably wasn't the mercury, but the powdered jade he took it with. That much force with an abrasive would cause a hemorrhage. Even if not for the jade, that mercury probably only did him in due to its sheer weight straining his intestines to the point of hemorrhage. Metallic mercury is not toxic, it cannot be absorbed by the human body. Mercury compounds, on the other hand, are extremely toxic.

The presence of those "adulterants" was previously believed to have little to no effect on the properties of the steel.

My best story of mercury came from an older co-worker of mine. It dates back to the 60s or 70s. Apparently, when he was at high school, the guy was left alone in the chemistry room at school for some task or other, where there was a hugely oversized test tube of mercury, somewhere in the multiple liters range on display. Even there we are completely outside anything that would be thinkable now. But the story goes on. He picked it up, and, for whatever reason, turned it over. Mercury being heavier than you would expect, the stopper came out of the vessel and all the mercury spilled on the floor. Did they call in the fire department? Have the whole classroom cleaned and refurbished by a professional waste spill cleanup company? No. The student was given a brush and a dustpan and told to sweep up the mercury, which he did. Of course what he swept up was no longer clean mercury but rather a murky, dirty mess. So did the teacher send it to a waste disposal specialist? No. He had the guy dig a hole in the school parking lot, dump the whole load in there and bury it. Is it true? I don't know, I wasn't there at the time. COULD it be true? Given what other things they did in the 60s and 70s, absolutely.

And then there was that one guy who was hit by a falling cell phone antenna in a storm... but other than that

One error they committed was using synthetic cinnabar. Iron is commonly found around cinnabar, and they (as ancients) likely didn't do an amazing job of separating only the cinnabar, a lot of other salts and metals were present in the crucibles, helping to extract the sulfur during the heat treatment. Also as vitruvius points out, it was when they tried to "dry out" that they found some mercury afterwards. meaning that water was also in the mix, likely the mines were humid and the used water as well to settle down the dust.

Subscribed. Great premise for a channel! I have a PhD in media history but know nothing about chemistry. I have a longstanding interest in art/painting and have been reading about the history of pigments for years. I never realized just how much trial and error goes into accessing and processing of materials like cinnabar. In fact, I was very surprised to learn about the vital role that metallurgy and alchemy played in all this. Even though alchemy led to a lot of quackery, it seems to be where a lot of practical knowledge was gained about all kinds of materials, including pigments for art and painting. I was also fascinated to learn about the role of early chemistry in synthesizing all kinds of important pigments in the modern era.

Seeing this documentary (and especially the latin bit passing on screen at 6:40, where they mention "emittit lacrimas argenti vivi" which can be translated into "issued live silver tears" ) I started to think about the fact that, here in Italy, we sometimes say that people (children mainly) that are overexcited and can't stop moving around have the "argento vivo addosso", which translates into "you have live silver on you".

Qin Shi Huang wasn't actually the first emperor of china, as China had in fact been unified many times prior (their history is actually one long cycle of fragmenting under civil war, reunifying, and then fragmenting again so many times that for millennia they actually assumed it was the natural order of things). The reason he's called the "first emperor" is actually a complex translation error. See, China is so ancient that it's oldest rulers are quite literally shrouded in myth; the traditional timeline says that the very first rulers were these demigods known as the "Three _Huang_ and Five _Di."_ But when Qin took the throne, he invented for himself the combined title of _Huang Di,_ (which all Chinese heads of state carried from then on), since he was just that narcissistic. Now in English the title of _Huang_ is usually translated as "Augusts" or "Soverigns," and _Di_ is usually translated as "Emperor," so you'd think that _Huang Di_ would be rendered as "Soverign Emperor" or something simmilar, right? Nope. That too is also translated simply as "emperor" for some reason. And since he was China's first _Huang Di,_ he is also erroneously called China's first emperor as well.

[@watatitamf1598]

I think he was considered first emperor because he was the first one who unify china under 1 government. The previous emperor/sovereign doesn't have direct control over entire china. They only control over vassal kings.

Mercury has a relatively high vapour pressure and the highest volatility of any metal, vapourizing to become a colourless, odourless gas. Cases of poisoning with mercury metal is always by inhaling the vapors. Until the 1990s mercury thermometers were fairly common in household use. The danger was when a thermometer broke in an unventilated room and the mercury metal was not removed.
