Metallic elemental mercury (what you see in the picture) is relatively harmless to touch. Arguably, it’s more dangerous to rub a lead ingot, for example. However, mercury vapours (and mercury does evaporate slowly but consistently) absorb quite easily when you breath them with a ton of undesirable effects, often related to central nervous system, which is never a nice thing. Broken mercury thermometer won’t kill you. Playing with the puddle inside a non-ventilated room might kill you in several decades. Working in the non-open-air environment where mercury is always present will slowly worsen your health as mercury accumulates.

Organic compounds of mercury are what actually is nasty. A short contact with a few millilitres of that — and you will have to recover for a long-long time, if ever. However, the scary stories about methylmercury rarely mention that there are other organic compounds that are just as toxic or worse. I wouldn’t get close to any organic cadmium compound, for example, and would be extremely wary of its inorganic salts too. The thing is it’s extremely unlikely that you encounter any of these chemicals ever in your life, and if you do encounter them, then you are likely a professional who knows exactly how and why you are to deal with them.

Nine out of ten hatters recommend that you don't do this. The tenth hatter purple monkey dishwasher.

(Victorian-era hat makers were notorious for going mad because they used mercury to treat felt cloth.)

Is this the origin story of The Mad Hatter? 🙄

[–] [email protected] 0 points 6 months ago

I think the original idiom was "mad as a hatter" which was eventually shortened to "mad hatter", possibly due to the Alice in Wonderland character.

Could have been. I know Lewis Carroll liked to lampoon issues of the day in his writing.

I'm kind of guessing the mad as a hatter phenomenon was known then, but don't really know.

I wondered what the Mercury actually did with the felt, as I couldn't think of anything from the top of my hat:

Mercury made the felting process in hat production more efficient. The compound used to moisten the fibers was Mercury Nitrate, a process known as carroting. It produced a superior-quality felt, which in turn, resulted in higher-quality hats

Mercury Nitrate

Which, should be noted, is not the mercury show in the picture. Mercuric nitrates are a white/yellow dry powder that is the result of mixing mercury with nitric acid. The process of making mercuric nitrates, and carroting itself, both result in rather toxic fumes that you really should not breathe in.

Handling liquid mercury is basically almost harmless as it absorbs through the skin really slowly and doesn't produce much vapours. Putting it in acid, heating it up, and putting the cloth treated with it in an oven is not.

Sneaky Simpsons reference here for those who didn’t notice.

I thought it was the vapours from using mercury inside that got them.

It's so much harder believing in six impossible things before breakfast when you're allergic to quicksilver.

I wonder what secondary compounds this was creating. Elemental mercury is pretty much fine, but if it was reacting with other things to create wacky fun times...

[–] [email protected] 0 points 6 months ago

I think it was mercury nitrate. Much more soluble.

they chewed the leather to hides to soften them, IIRC. so it wasn't just getting on their hands, they were ingesting it.

This kills the idiot.

Pure mercury metal is pretty chill, just done fuck with organic mercury compounds

[–] [email protected] 0 points 6 months ago

Vapours too.
