Most interesting video i ever saw...

Ever seen what mercury can do?

I have to wonder about someone who would play with a substance as toxic as mercury. Maybe they've done it too often already? [:D]

Well saw another video of him, said something he mined that mercury from cinnabar on rocks, etc. There a video he was talking about it and showed a mine in the ground and forge of some kind to draw the mercury from it. It was interesting.

Mercury is toxic in theory, but then so is lead, copper, and several of other metals. Mercury gets it's bad reputation because of the well known effects on hatters in the 17th century, but they were heating up their mercury and so generating mercury vapour which they then breathed in. You would also need a lot of surface contact over a very long time to ingest a significant amount through the skin.

The Evaporation Rate of Mercury at room temperature is so low that it can't be measured so there is no mercury vapour in the local atmosphere, which means that there is none to inhale. But nowadays Health and Safety legislation is so all embracing that it's not PC to give the situation some thought rather than taking the Material Safety Data Sheet information at it's most literal extreme.

Lead is very deadly even more so than mercury, it does not matter if it is jacketed with steel or copper, what matters is the feet per second . . .

Mercury was the main treatment for Syphilis before antibiotics
were introduced. It was rubbed onto the skin as an ointment.
Another treatment had the person locked into a sauna so mercury
vapors could be introduced via sweating pores.

Many Syphilis patients died from mercury poisoning. But, it was
a known risk. They knew it was really dangerous but it
was the only known way to treat the ulcers/lesions. The
treatments were given on a continual basis.

This led to the wry adage, "A night with Venus, a lifetime with Mercury".

i could watch his videos all day, learn from this guy. interesting stuffs.

Too bad he didn't use a chunk of lead instead. [;)]

Makes me wonder where he got all that mercury. I would think it's hard to come by due to it's toxicity.
In this form it does not absorb real fast into tissues but it's still dangerous. Heck many of the minerals in my mineral collection I handle with gloves!

Well he mention that his dad or grandfather knew where they were, i assumed they were miners from the pass. Plus he got connection to people that do alot of this stuffs.

Its very dangerous, mining coals, leads even golds. Get too much into your lungs, then you are fried and cant be fatal in some situations.

Here the video i mention, Where did i get my mercury?

The evaporation rate has a lot to do with how much surface area is exposed regardless of what the subject is. One square centimeter would take an exceptionally long time at room temperature (`70F). The surface area in the plastic tub in the demonstration is considerably more than one square centimeter.

And regardless of, 'don't do this at home', you know how rampant stupidity is in the world.[:D]

Even before the advent of Youtube people did stupid things. A friend and a friend of his decided they would make an explosive. I think gunpowder. They gathered the ingredients and while the friend of a friend was mixing some ingredients together they exploded in a pestle he was holding. So, the friend of a friend has the honor of only one hand and a badly scared neck, chest and arms. It almost killed him.

So I do have reason to take exception when a knowledgeable individual shows stupid people how to do dangerous things. [;)]

Mercury isn't difficult to come by if you have an account with a supplier, but it's expensive. I dread to think how much that lot cost.

When the evaporation rate is negligibly small then the total amount in the atmosphere remains essentially zero, however much mercury is there and however long it is present.

When they tore up the original wooden block floor in one of the labs I used to work in, they found quite a large pool of mercury underneath which had obviously dripped through the gaps between the blocks sometime in the past. I'm sure it wasn't spilled during my time there so it must have been there for many years. But as it doesn't evaporate at room temperature, no problem. I just cleaned it up for the worried building contractors. [:)]

If you are still worried about him breathing in any harmful vapor that might magically have escaped into the atmosphere, well he was working in the open air, not in a confined space.

But it DOES evaporate at room temperature. [:D]
One square centimeter would take somewhere in the neighborhood of 8200 hours to evaporate. That's a one square centimeter globule. At room temperature. That's about a year. It's prolonged exposure that becomes a problem. Being in a class where you spend maybe four hours maximum for a handful of days a week for a few months, even if you are the prof, wouldn't be a problem. If you lived there for years and there was mercury present the whole time then you might have health issues.

This is how it happens:

In 1989, several pounds of liquid mercury spilled in a child's bedroom. The mercury was not cleaned up sufficiently. He and his two sisters continued to be exposed to high levels of evaporating mercury for a prolonged period, and they suffered serious health consequences. (Source: CDC.gov)

Stupid people do stupid things. Someone will try to do this very same thing without any knowledge of what they are doing. You can take that to the bank. [;)]

How about when people use mercury to dissolve gold then use a blow torch to vaporize the mercury then the gold remains? That is done in some mining operations.

How about when the recycling items are sent to another country without pollution controls or one where the controls are not enforced, then mercury and other chemicals are used in the recycling then the mercury and other chemicals get released into the environment?
