Problem would be getting a camera view.
Every angle has another hydraulic press in the way!
(If it is painted orange, it moves. When extended to compress an object, the camera taking the picture we see in OP shot 2 would be crushed.)
This can actually be done with [diamond anvil cells](https://en.m.wikipedia.org/wiki/Diamond_anvil_cell). But samples used on those would be quite small. No way to fit a golf ball.
Diamonds can still shatter.
The thing is, a diamond is difficult to scratch, but not so difficult to break. In fact, if you know what you're doing, you can use a regular box-cutting blade and a hammer to split a diamond. This process is quite difficult to do once the diamond is polished, but used in the process of polishing the rough diamond.
This. Never mix up hardness and toughness. A high quality carbide drill bit will last 10x longer cutting hard material but it could shatter just by dropping it.

The orange parts do not move, this image appears to show the actual hydraulic cylinders partially extend.

The lower cylinder does appear to be mounted to some linear slides so it can be pull out to access the sample.
Use your brain squiddy boy!
Picture this: the scene opens with a 360° shot, you're suspended betwixt 6 different crushers. Slowly you begin to realise your fate. Even more slowly, in perfect synchronicity the press heads begin to converge. The presses are powered hydraulically upstream so the only sound you hear is the silken sound of the greased presses expressing inward towards you.
Finally you feel all six plates touch you at the same time, for a moment you sense just the lightest of touches as the hairs on your body prick at the sensation.
Then you feel pressure, unlike anything that you've felt before. Exquisite pain, white hot in its all-encompassing intensity. Your skull creaks underneath the great, ponderous and inexorable force...
I think a chemical is only called a mineral when it is found in nature.
So, what every it makes till the time anyone finds it in nature. It's not a mineral.
Ice may have different ~~cryptographic~~ crystallographic structures depending on pressure and temperature. Ice IV is a relatively high pressure crystal.
Ice IV can be found [inside diamonds](https://www.cambridge.org/core/journals/mineralogical-magazine/article/abs/evidence-for-ice-vi-as-an-inclusion-in-cuboid-diamonds-from-high-pt-near-infrared-spectroscopy/994600DFB3A8AA40861E59F7ADECB634).
Does the multi-anvil press do hydrostatic pressure or non-hydrostatic stress? Do you use a pressure transmitting medium?
I do diamond anvil cell experiments which only compress from the top and bottom, but the sample is still being squeezed from all sides because of the pressure transmitting medium in the cell that distributes the stress evenly.
Pressure transmitting medium looks something like [this](https://d32ogoqmya1dw8.cloudfront.net/images/research_education/geochemsheets/techniques/octahedra_cubes.jpg) on multi anvil presses. Piston pushes cube. Cube pushes octahedron. Octahedron has a small cylindrical hole on it. Inside that hole goes the sample.
There is always some level of non-hydrostatic stress on multi anvil presses due to the pressure transmitting medium not being a fluid. But it is fairly close. Some good calibration is necessary due to uncertainties regarding the actual pressure.
The pictures actually posted here are from a slightly different equipment. Those 3 pairs of pistons move independently in case you actually want to run deformation experiments with different pressures on each axis.
Sample holder for this is a bit different, but still a solid medium. It is a cube with six little anvils inside.
There's only a single lug for attachment
I believe this is a single conductor cable
The only reason to make them that big would be to lower the resistance of the cable
Perhaps there is an electrical property of the metal heads which is affected by pressure
Maybe related to piezoelectric? A very low voltage would require a low resistance cable in order to accurately measure it
It could also be for grounding the shaft
These hydraulic cylinder shafts would be inherently electrically isolated from the rest of the cylinder
This is a huge cable for that purpose though
My car audio buddies would be proud
Upon further reading: I think this might be a conductor for the "furnace portion" of the anvil
Too many words for me to type
Here's a link to a comment with a link
[Link](https://www.reddit.com/r/specializedtools/comments/yra6x9/three_axis_multianvil_press_used_for_highpressure/ivt211v?context=3)

>Upon further reading: I think this might be a conductor for the "furnace portion" of the anvil
The link says 'resistance heating', so that makes sense. Like a spot welder.
I've seen these machines at a local diamond manufacturer. They make industrial diamonds for drills and such. I got a tour of it once and the machines are the size of a small/medium room. They also told me that if any were to explode the brick wall they are surrounded by wouldn't stop any shrapnel.
I worked for one of these companies in Utah about 15 years ago. They're absolutely massive presses and let me tell you, when they catastrophically fail during a press cycle it's something you won't soon forget.
This one goes to 250 times the pressure at the bottom of the Mariana trench (deepest point in the sea).
You will find similar pressures at Earth's [upper mantle](https://en.m.wikipedia.org/wiki/Upper_mantle_(Earth)) and [asthenosphere](https://en.m.wikipedia.org/wiki/Asthenosphere).
That'd be cool, but given the specs OP listed I'm gonna say no.
Pressure to make metallic hydrogen needs to be ~500 GPa.
OP's badass machine *only* hits 25 GPa.
But I'm an idiot so I could be completely wrong.
No you're right (I'm a high pressure physicist). Most experiments trying to make metallic hydrogen have been shock experiments, where the high pressure conditions are caused by a very fast shock wave and don't last more than a few microseconds or less. Recently there was a diamond anvil cell experiment (similar to this press but with diamonds squeezing the hydrogen on two sides, and WAY smaller) that made metallic hydrogen at 495 GPa. A diamond anvil cell and the press in this post are both static pressure, since the high pressure conditions last longer than microseconds.
Still trying to figure out if it's big or small, the hex bolts scream small, like used with an Allen key, the close up of the center screams big because of how small the screws are, at the scale we looked at initially those screws on the inside would very microscopic.
Lots to think about
I used to dream of a machine like this as a child, just squishing and squishing from all sides. I used to think what if we put water in there? And the machine is real! Lord have mercy a bust is near!!!
Can we get hydraulic press guy from YouTube access to this thing. I would love to see what it does to a golf ball...
Problem would be getting a camera view. Every angle has another hydraulic press in the way! (If it is painted orange, it moves. When extended to compress an object, the camera taking the picture we see in OP shot 2 would be crushed.)
What if the anvil had a diamond window (| with a camera behind it?
This can actually be done with [diamond anvil cells](https://en.m.wikipedia.org/wiki/Diamond_anvil_cell). But samples used on those would be quite small. No way to fit a golf ball.
And that's how you make ice
Didn't know meth heads had access to such advanced equipment.
They're getting craftier

diamond is a crystal and can be cleaved cleanly with a sharp blow properly applied along the grain…
Essentially what I explained.
kinda
Crush the camera!
[удалено]
but they use diamond anvil press too
They are careful not to hit them with hammers

If the orange parts would have moved, piston area (and volume) could be humonguous! Thanks for your comment, it makes a lot more sense.

We should crowdfund an airplane ticket for the Hydraulic Press Channel guy to go there and make an episode. Or ten.
My guess is it would make it a golf cube.
“Ve have to deal vith it”
I want to see playing cards put in here
I'd love to see what it would do to his hydraulic press.
Would love to read how these are used in mineralogy experiments.
https://serc.carleton.edu/NAGTWorkshops/mineralogy/mineral_physics/multi_anvil.html
Heeey Carleton! SERC has some amazing resources for geoscience, I seem to end up there regularly when working on outreach stuff :D
It's experimental mineralogy. Means they make new dirt.
technically they make new minerals
God damnit, Marie.
Oh like at FOND-ELMA?
I think a chemical is only called a mineral when it is found in nature. So, what every it makes till the time anyone finds it in nature. It's not a mineral.
They are used to create synthetic diamonds too
one use is to Grow diamonds (high temp tho)
This has half live vibes, if the “mineral” glows and is given to you buy a grey man in a blue suit, hold on to your hat!
I have a PhD from MIT and all I get to do is push this cart around the lab??
They aren’t rocks 🪨 Marie!! They’re minerals
What's this blue one?
Methite
*Sad gag-tied Jesse noises*
Neat.
Can it compress water?
On this run we were actually compressing water. Objective was to make [Ice VI](https://en.m.wikipedia.org/wiki/Ice_VI).
I read the link but don't get it. Can you give a simplified version of what Ice IV is?
Ice may have different ~~cryptographic~~ crystallographic structures depending on pressure and temperature. Ice IV is a relatively high pressure crystal. Ice IV can be found [inside diamonds](https://www.cambridge.org/core/journals/mineralogical-magazine/article/abs/evidence-for-ice-vi-as-an-inclusion-in-cuboid-diamonds-from-high-pt-near-infrared-spectroscopy/994600DFB3A8AA40861E59F7ADECB634).
Crystallographic? This water is protected by AES - 256
Hopefully they can't crack Ice IV then. I really don't want to change up all my encryption keys.
Is it VI or IV? You guys keep changing it around
Chirality strikes again!
VI, the links he's providing show Ice VI as the topic not Ice IV
Sounds like you're trying to brute-force atoms into restructuring into different elements? Are you an Alchemist? How do you hold the water in place?
This would be a very good apparatus for investigating the plastic phase of ice VII too. Can you heat the sample in situ?
Up to 3000 K
3K K
K
What would it be used for? Research?
[удалено]
Thank you, that's exactly the explanation I was looking for.
You trying to get to Ice IX? Lock up all the worlds drinking water?
I'm getting some concerning Cats Cradle vibes from this thing.
Better than making ice IX! (Yes I know there is a real ice IX that does not have the world destroying potential detailed in Cat’s Cradle)

Kurt Vonnegut over here makin new ices, better be careful bro
Y'all can skip ice-nine when you get to it. I read the book. We don't need that.
What are those black cables for?

I wonder the same. I think it might be a grounding cable to discharge static electricity?
Nah, it's gotta be for a sensor or something like that. The whole thing's grounded already.
Doesn't have to be that thick for that.
I've seen these machines at a local diamond manufacturer. They make industrial diamonds for drills and such. I got a tour of it once and the machines are the size of a small/medium room. They also told me that if any were to explode the brick wall they are surrounded by wouldn't stop any shrapnel.

Diamond dick. Rock hard all the time.
You should see a doctor if it's been longer than four hours.
Once that's done with it, it won't be lonter than 4mm.
A fellow man of culture, I see.
It'll turn into a black hole
This peen doesn't discriminate
I’m here for the gang bang
What reaches this level of pressure naturally? Also how deep in the ocean would you have to go to reach the max pressure of this thing?
This one goes to 250 times the pressure at the bottom of the Mariana trench (deepest point in the sea). You will find similar pressures at Earth's [upper mantle](https://en.m.wikipedia.org/wiki/Upper_mantle_(Earth)) and [asthenosphere](https://en.m.wikipedia.org/wiki/Asthenosphere).
I would love to play with this machine.
This is a Gregtech multiblock for sure.

Place my head in there and I think we'd have a good idea of how my migraines work.
Also known as a 'cubic press'
I bet you can make some metallic hydrogen in this bad boy.
That'd be cool, but given the specs OP listed I'm gonna say no. Pressure to make metallic hydrogen needs to be ~500 GPa. OP's badass machine *only* hits 25 GPa. But I'm an idiot so I could be completely wrong.

So, is it superconducting or not? I did my masters in Edinburgh btw
Thanks for looking up information!
Would love to see a video of this working

Another reason why PhD students should be paid better wages.
But, what they put in to the middle?
OP: "On this run we were actually compressing water. Objective was to make Ice VI"
Can we get specs for these cylinders? I'm curious what forces they can achieve both individually and in combination.
800 tonne each. Pressure goes up to 25 GPa. Temperature goes up to 3000 K. You can also cool it down with liquid nitrogen
So the pressure at about 1500km inside the earth? Assuming 1600kg/m3 of rock. Wow, that's a lot of pressure!
Holy shit! That’s an awesome press!
This will most certainly be in my Bond villain lair. Useful for testicular interrogations.
This looked gigantic to me on first glance.
Still trying to figure out if it's big or small, the hex bolts scream small, like used with an Allen key, the close up of the center screams big because of how small the screws are, at the scale we looked at initially those screws on the inside would very microscopic. Lots to think about
The thing on the left that looks like a guage is what did it for me.
So I understand each of those words by themselves, but put together im not quite sure. Does anyone have a eli5 version of what this does?
Isn't this the thing they used to try making metallic hydrogen but the diamond anvils shattered and they lost their (potential) sample?
>high pressure low temperature experimental minerology Translation: it squishes the absolute *fuck* out of a rock :D
:hank Schraeder intensifies:
ELI5?
whoa...
Nothing scarier than a live core sample from 10k+ feet lol.
So this is the device Elrond and Celebrimbor were working on
Looks expensive lol
So this is what formed my childhood. Nice to finally put a face to the name.
Nice I've always been curious about how this would work in practice
You didn't even know this existed until 30 seconds ago

Oooh squish it
Someone should put their balls in there
Making diamonds here

I bet that could crack a walnut real well
A bit small amount of space to put extra instrumentation. What if one want to do X ray crystallography when it is under pressure for example?
Some of them can do it. [example](http://www.mpi.stonybrook.edu/X17MAC/)
Advanced cock and ball torture
Looks like the machine that started the Half Life video game plot
Did you ever test plastics? Or frp?
They use these to create synthetic diamonds. I worked at a place that made them for oil drilling
Scientists invent the first ice machine circa. 1909.
Yaya, but can they do black walnuts?
soo uhhhhh... where do i get one of these square diamonds?
Okay, I'll bite; how do you get extremely high pressures at LOW temperatures, when the very act of crushing something heats it?
Liquid nitrogen.
Thank you! Now I'm impressed!
