I'm currently fighting cancer right now, and your videos are one of the things that I look forward to. Thank you Nate and Grant for making such great videos!
get well
I pray that you have a quick recovery i have a friend that has leukemia.
Get well soon bro
Britnie Levi I'll pray for you.
Get well soon
Your fired clay one was actually a GREAT casting medium, but you forgot to pre-heat the mold! Try it again with your fired clay mold pre-heated in the oven to remove any humidity it might have absorbed. It should also have been thicker-walled. You can also set the fired clay mold into a sand bucket to help cool the metal slowly and prevent the expanding cooling metal from pushing the mold apart. One big advantage is that clay is really easy to work with. You could easily write something in your clay before firing (mirrored), and get something legible after casting.
Dried may have worked if it was oven-dried too. I think this was part of the problems with the grill-firing in the other video. (Not exactly dry enough. What's considered trace moisture by most observations is still enough to cause problems.)
And glazing ceramic clay would be another cool experiment
Lowest heat glazes usually go from ~1100C on, and melted aluminum is only 660C, so yeah a glaze would at least prevent it from absorbing more humidity, and make the surface smooth for melted metal to just slide right over. But really just preheating the molds without glaze (and without cracks ideally) to say 450F for 10 minutes before pouring would greatly reduce thermal shock and would eliminate steam bubbles.
Other types of clays can be pretty easy to work with and more stable to temperature changes. There was a foundry near my home town which cast a lot of intricate metal parts in clay based shapes.. they used local clays which have high bentonite but I don’t know the mixtures... I suspect they were a commercial secret
HMan Actually, there are some cone 022 glazes that are roughly 650°C.
Im a ceramic artist and if you would have wedged your fired clay before you fired it and let it fully dry before firing it wouldn't have had cracks in it and im sure if you did but you should use a real ceramics kiln this will let you know if you have fully fired the clay to zero moisture content. Also using a type of clay body that can absorb the rapid temp shock such as porcelain or Raku Clay it would have worked better and would have a better chance of not cracking.
Okay but he wanted to see if he could fire clay in a Barbecue grill. It was kinda the whole point of the previous video
Yes, but if he wants to see if fired clay is a viable option for aluminum casting, he should have used properly fired clay instead of the one from the previous video.
Plus heating the clay just before pouring would reduce thermal shock. I wonder if coating the clay in sand would help?
Wow! That's smart
Namjoon's Butt .omgsame
Fun fact, the capstone of the Washington monument is aluminum, because it was worth more than gold at the time the monument was completed!
I feel educated now
Yeah at the time it was really freaking hard to extract the aluminum from soil
@Nij Jin Nope, Aluminum at the time was a VERY rare metal and as expensive as SILVER and even harder to process/melt/cast in the dimensions that were drawn up for the capstone, at the time it was cast it was the largest single piece cast in the WORLD. It was also a record for the time in terms of purity, a 1934 analysis showed it had a purity of 97.8% Aluminum and barely any impurities, a rather big feat for 1884!
@Nij Jin it was to protect the monument from lighting
Ya'll out here with all these facts and im just here with my ramen just clueless at whats going on...
Again, Nate you’re doing great! Really like the behind the scenes shots!
So did I.
I aswell.
Am I late?

Lol Nate's so cool he's like a really excited puppy
Hmm, what kind of puppies are u used t0???

Maybe I've had slag hit me in the eye and nothing happened
Someone's probably gone into scientific explanations for each type of clay, but from the viewpoint of an art kid, I can give a general idea as to why the dried and fired clay did what they did.
With the dried clay, it was probably just air-dried, meaning the inside still had a small moisture content. That's why the temperature of pottery kilns is slowly increased over at least a few hours, to gradually dry out the clay without cracking. When the molten aluminum was poured in, the temperature skyrocketed, so rhe moisture and heat clashed, causing the clay to ezplode from the force of the resulting air bubbles.
As for the fired clay, there's only so much heat that can be applied directly to clay before it becomes more fragile than say dried clay that is easily misshapen or broken. Adding more heat to a fired piece wants to remove moisture that isn't there, which can cause cracks and breaks.
Did any of that make sense? Probably not. I'm dyslexic and basically unable to see properly, but I wanted to share.
Your spelling and grammar are near perfect aside from a few small mistakes here and there "so rhe moisture", "ezplode" which appear to be simple typos. R is right next to T, Z is right next to X, etc etc. If I were to diagnose you just from this, I wouldn't say you're dyslexic in the slightest. Though, I don't know the extent of your difficulties so I can't refute that you are at all. :P
Just saying, the only problems I saw were simple typos. Your typing is otherwise significantly better than many others I've seen. Might I suggest getting Grammarly for your browser? It'll catch simple typos like that and even point out any errors in your grammar, hence the name. It's not an autocorrect, though, so no frustrations there. ;)
i had no problem understanding what you've said and your information was useful :)
Great work Nate! Glad you can step in to keep the experiments going while Grant works on something random (and awesome I'm sure).
Oh my gosh, Nate, please wear safety glasses! This is a really cool demonstration and experiment, but I get really worried for your and your camera-guys safety when you work with potentially dangerous material without obvious PPE. Keep up the fun experiments, but please take care? I do think you are doing an awesome job sharing your clear excitement and pure joy for science.
he wore a weldimg mask
it's all fun and games till someone takes molten aluminium to the skin
Only after something already exploded, though, Michael.
Precaution from the start is way smarter--and safer--than taking precautions afterward.
RBabik Ii or until someone's frozen solid
need a collab with the slo mo guys when for when the clay explodes
Ethan Alker if he collabed he’d get more views
SergeantSpoon Right!
Try putting liquid Nitrogen in a really hot Liquid Copper
Tataram K Chawan wouldn’t that explode from thermal shock or some madness?
hot vs cold...
*Aluminum twizzlers!*
TechByte probably easier to bite trough then normal ones

You will defenetly have cavities after eating
Hee Grant,
obviously there are more people working on the video's then you and Nate.
Can you introduce us to your team?
Jan Jaap van der Most the kings of random
the kingdom of random
AirPls that’s a better name.
Jan is that you from sam and niko/ corridor digital?
An introduction to the Court of Random.
Very interesting results. I was not expecting any of the outcomes, but I always love to watch metal melt.
Your the best guys in the world you made me smarter thank you for that Nate and grant
overwatch master you’re
Be careful Mark
You don't tell me what to do :)
Specific Love Creations
Yeah right, as Robin would say "holy melted metal minute men, this could be dangerous"
Hi
I love the mouse for a bit then a little more about this job I have you put in the order I
Sssssssxsssssssssssesxsssssssssssssssssex
I’m loving the videos every day. Keep up the good work Nate! Loving the content you are putting out
That was so amazing! My adrenaline started pumping just watching! I can only imagine how you two felt!
Can a metal mold be used to cast the same metal as the mold??
it would bond with it and become one cohesive block of metal so no
What Elmo said. Imagine trying to use an ice cube tray made of ice.
He has done it before when he is using the steel tray for baking for aluminium casting and it doesn't stick to it , look for H13 die casting
No
@@razbuzz4147 I have permanent aluminum mold. Its a 2 part mold for a 10 inch bell. I make a core in the pattern bell and the top mold which shapes the outside of the bell is pure aluminum. I pour molten aluminum in the top hole and cast bells that way. The metal of molten aluminum does not melt the aluminum cope and shrinks away fromt the mold walls and when it cools i knock a bell out with a rod. Works every time. Molten aluminum will not stick to solid aluminum .
Negative X experiments please!
Nate is the man. I'm liking this channel more and more
I loved it when these videos were almost more diy-ish. I still love the new ones, but these how to do random cool stuff videos are always so fun :)
Sooo cool! The explosion was the best!
What if you put wet clay in a vacuum chamber
Jeet Sharma nothing
There is no air in clay and even if there was air in clai it would just blup and stay put
This could be interesting you can remove water with a vacuum chamber you could end up with clay that cracks less when fired
Jeet Sharma INCREASE YOUR KNOWLEDGE BY WATCHING MY CZcams CHANNEL FOR AMAZING INFORMATION AND MIND BLOWING FACTS AND SHARE AND SUBSCRIBE!!!!!
Nothing
hwhat about the moisture in the clay ? what will happen to it? will it causw the wet clay to expand?
If you put food coloring in water and then put it in the distiller you used in a previous video and would the food coloring evaporate with it and land in the top or would it stay behind
Trevor Ogilvie would like to see that one too
me to well 3 really
Trevor Ogilvie most food dyes have an atomic weight of around 400 to 800, water has an atomic weight of 8. It would most likely stay behind.
Trevor Ogilvie
Each color is different. Some food dyes evaporate with water, others do not.
Food dyes are not an atom, so that would be mollecular weight
That explosion WAS SO COOL
I use to work in a foundry and we used a liquid solution on our sand that i am not sure what it was made of but that is how our casts packed together so well and stayed firm during the pouring period.
You are doing awesome Nate
Can you melt metal and quickly freeze it with liquid nitrogen plz
Momiji hardwired on caffeine it would be awesome. Everyone loves watching explosions.
Yes that would be great
Thermal shock is always fun
I was not expecting that!!
Fired clay molds work best when their thick and encased in a box frame to hold pressure, they are also typically one time use things since the mold becomes brittle so anything that isn't designed to slide out when done (like an ingot) the mold is broken to retrieve the cast... it's actually where the term "breaking the mold" comes from. So I suggest if your going to try using clay molds, make sure to mold the outside to fit into a some kind of frame.
Hard to believe this is Nate’s first job in front of a camera, he’s doing very well. His videos are as great as Grant’s 😊
What does Molten Metal do to Jake Paul?
what is 'Molten'
cures the world
Slow painful death exactly what is needed
grim death
Some nasty burns xD
I am doing this for a year know and you make a VIDEO thanks !!!👌
I love the way you got the aluminium. It was satisfying in some way.
THANK THE GLASSES FOR MARK NOT GETTING HIT BY A SPITTLE OF ALUMINUM
if it his skin it would be like liquid nitrogen sort of
lol spittle
You must have a couple people editing videos to get them out this quick.
Or they make them ahead of time and schedule them.
or maybe a magic editor
.... or donkeys? Yeah, I'm almost certain that donkeys are somehow involved....
Or ... they just record a video in 1 part
He definitely has editors, it makes sense if you knew how big CZcams channels work
*hey, I just thought of something, you said that the weight of the metal would sometimes cause the sand to break apart right? What about if it was compacted ? the biome would be easy to compact, but if you come packed at the sides around the foam maybe it wouldn't do that?*
This is the definition of cool, glad nobody got hurt thanks
I Wondering What Happen When You Melt Magnet??
Gaming With Dan a magnet is a material with all its atoms facing the same direction (atoms have a slight magnetic charge so when they are all facing the same direction the charges add together giving a strong magnetic force), if you heat up a magnet you simply make all the atoms move about and face different directions making the magnet lose its power.
Skyler Extravaganza that wouldn’t happen when the magnet gets too hot it loses its magnetic powers
Skyler Extravaganza That's not how it works.
It would lose the structural alignment that is responsible for it being magnetic
Once it passes the Currie temperature it loses its magnetic properties and then it’s just a hunk of iron
can make a knife sharpner ?
"Holy heat batman" 😂
Wow! That is really cool
The only reason why it exploded in the unfired clay is because it hadn’t been bisque fired to remove the air bubbles so when the heat hits it all at once it starts to expand the clay forcing it to explode the wet clay didn’t do that because it hadn’t had enough time for it to solidify the air bubbles in the clay so they escaped through the top of the clay
A bisque fire actualy removes any remaining chemically bonded water. Any air bubbles worked into the clay can lead to explosive results thats what process like wedging/kneading are required and why de airing pug mills exsist.
Top-notch stuff Nate!
Great video. Thanks for sharing
Clay, you're FIRED!
Can you cut the aluminum in half so we can see the air bubbles in it? It seems like it would make an aluminum sponge.
S P O N G E
Can you try putting the dry clay into the vacuum chamber to remove all of the moisture before casting with it?
Well, this saved me a lot of time and experimentation.
exactly what I needed to know thank you so much!
Should try firing the clay on top of the furnace and then pour when the molds still hot
Make a foundry with clay!
Love you nate!! 💗💗
Cool u turned aluminum to foil omg omg it's legendary.
ALI-A intro plays
The thumnail looks like Aluminium coconut
Plus i have a playlist in wich i add videos about/casting metal everyday playlyst called *_Metal_*
Sorry for my bad spelling
Me and my grandad always used to cast lead in wet clay molds and it always worked perfectly!
not all heroes wear capes. some have cameras.
These videos are awesome (metal melting) please make a playlist with all your metal melting videos
Glad you're okay. That was a close one!
Great video, Nate! I'm really enjoying these!
When did mate happen? Where's the King
Watching aluminum melt is SO satisfying
More weekend projects please.
Awesome videos! Keep 'em coming guys!
Suggestion: pour it into cold water 😉
MCP - Minecraft & Programming that would make really cool shapes
Next up: Will molten aluminum cook human ocular tissue?
Follow up: Ocular surgery! Is it even covered?
Curious, what if you added a small amount of clay slurry to send mixing it will? When working with clay there’s all kinds of clay with different firing characteristics. Air bubbles is the biggest problem in all clays. Porcelain clay I have never worked with.
I have cast aluminium successfully with an "air dry" terracotta brand of clay from the local arts and craft store.
I had it in the kiln for about 30 mins first, as well as using the oxy lpg gass torch on it to remove any moisture and heat it up before the cast (if you don't heat it up first it may crack).
A home made starch based air dry "clay" works alright as well, but the edges could flare up causing loss of detail. The starch mixture is extremely heat resistant (corn starch, pva glue, water, glycerine).
Amazing
What happens if we boil gallium
The world is vapourised
Gallium gaz?
Hey, can you maybe make a video on melting, and casting steel?
the bubbles and the surface defects on the top on the fired, dry, and wet clay version was from moisture that was in the clay that was driven out in both the fired and dried. Your fired clay wasn't "baked" enough... the heat also drove out super heated water to the cement - which was considerably cooler. That caused condensation to form around the fired clay.
hey watching from Pakistan and still love your videos
Try making sheet metal!
Tabeeb Rahman you know how many steps it takes to make sheet metal?
Milan Meiland ovb he dosent
Milan Meiland, cast a block of your alloy of choice, temper, roll until you approach the max cold work percentage of your material of choice, temper at recrystalization temperature, roll, repeat to your desired thickness, shear, heat treat, store/sell/use. That or you could run the molten metal through a die until it approaches its supercooled state within about 10% of your final desired size and hot work(roll) from there to your final desired size.
Looking at the result in the video, I recommend trying cured cement. Use fine sand in the mix. Heat it first before use.
Hey great
Vids as usual, have you thought about adding graphite to the clay you collected and making a crucible for your trash can foundry?
Rip Clay bowl
Exploding clay has gave me shock!
In a previous video you used coffee creamer as the fuel for your Mini Flamethrower, but what if instead of coffee creamer you used the colorful smoke powder?! Would it create a beautiful display of colorful fire and smoke, would it be the same as normal, or would it not even work at all? Only one way to find out!
Sciion colors usually don’t make things different colors when burning, it’s usually random chemicals like borax or sodium chloride (table salt)
Will something cast in proto putty like metal or glass or would the proto putty just not work at all?
it would melt
The King of Random
You should try Hydrophobic sand, it would be a cool experiment to try.
also, I think it would be really cool to see the team do experiments with ferrofluid.
maybe try solidifying the ferrofluid, or maybe try mixing gallium with ferrofluid and then see what kind of really cool proporties the new mixure has.
The fired clay would have worked better if it was fully cooked in a kiln. Putting it on a BBQ only cools the surface. Try cooking the clay in the forge
not exactly, sure u fire it again to cook the glaze on it but that metal probably gets hotter then a normal kiln so it could break it like it did in the vid
Might be a little late, but it would work much better if he heated the fired clay up first, thermal shock is a large problem.
aluminium melts at 660 degrees C, which is substantially cooler than a typical pottery kiln.
Fully firing the clay would help, and also using raku clay would help. It's made to withstand a certain amount of thermal shock.
why dont you try to fire your clay with the molten metal
Tyangsa N thats an interesting idea
He did that i the video, He got a Dry spot
only on the inside what if you bath the clay with molten metal
the same thing, but instead of exploding sideways it will explode into the air and clay will hit everything within its reach..
your amazing king of random team! ::D
Love this guy
Will the backyard foundry melt rocks?
No. The arc foundry will.
Can you do a "What happends if you take liquid nitrogen / dry ice in a cup of molten metal?"
they just did that, nothing happened.
PressTube uses a oil based red colored sand for his castings and they come out looking great even with the foam mold method
I was thinking about casting aluminum inside hollow aluminum square bar to get a solid bar as I couldn't find it nearby but I didn't try it, would be nice to see you tryin it
what would happen if you poured molten aluminium straight into cold water? i tried this with wax and the wax spread out like a sheet!( i did it in a bucket). i wonder if you could make some aluminium sheets in this way
Wax and aluminum are not at all the same thing.
2 chances, the water would be explodin and impullses the molten metal to the air.. or the aluminium goes to the deep and the water starts evaporating like mad...
Wax works like you say I guess because it would float on the water when getting solid and also it doesnt allow that much heat transfer... aluminium on water would be closer to put hot oil on water... (that temps differences makes the water turn into gas so fast that it almost prevent the oill/aluminium to actually "touch" the water... like forming a gas-based shield all arround the material, which if is a small amount would float for few time (unestable) or a big amount probably will be forced to move on a lot of directions so then exploding and covering the surrondings)
u should make clay rectangle forms and make aluminum bars
Thanks for this video,you kept me from wasting a lot of time.
You can make a mould with resin coated sand. I used to deliver that stuff to foundries all over the mid-west.
you should really get real casting sand, its sand with high amounts of clay and not the "green sand" you guys use.
Nate you are doing well thank you
Well, this is all extremely explainable.
The fired clay hadn’t been fired all the way. There was still some water in it, which is why it puddled up underneath and why it was so fragile.
The dry clay still had a lot of water in it, but it was rigid, which is why it exploded. The water vaporized inside the hardened clay and the pressure caused the explosion.
The wet clay didn’t explode due to the pliability of the wet clay.
I greatly enjoyed watching this video.
I went camping and i thru aluminum cans in the campfire and they melted pretty fast and even thru glass bottles and they also melted not as fast but did after couple minutes could a camp fire work for casting? It would be cheaper
Yay Nate!
Yay Jessica!
Thumbs for Mark the camera man!
whyd u copy the top coment
wat if you vacuum seal it so no air to create bubbles in the metal or you can v-seal it after you poured it in right after.
