SPOILER: Aluminum and brass mixed together make "alumabronze". Technically alumabronze is supposed to be made from aluminum and copper, but since brass contains copper and the zinc burns off during smelting, it's more-or-less the same thing.
@@Sugarsail1 Not always, depending on its specifications, it might use something like silicon instead of or alongside of tin. while the last one was *close* to aluminum bronze, there was still too much aluminum in the mix to create a usable alloy.
@@olinseats4003 yeah, 25% ali is rather high. 14% is the high end for Aluminium Bronze (to give it the correct name) because as we see here, the aluminium and copper have such different atomic sizes that it doesn't have much strength in the middle, only at the end of the ranges.
Copper Aluminide! CuAl2 is likely what you've made here and removed most of the zinc. This is technically a solid solution - not an alloy - since there are intermetallic bonds. Just about all intermetallic bonded materials are incredibly brittle because of the rigidity of the structure. Awesome experiment!
Thank you for pointing that out way better than I can. Cliff notes for those that cannot follow. If brass is composed of copper and zinc, and you burned off the zinc by getting the mixture too hot, you no longer have brass because you do not have the zinc. so that was a mixture of aluminum and copper. Lastly, the rapid cooling of the metal is what made it even more brittle; air cooling would have resulted in a stronger compound and a lower brinell hardness.
take a bang snap (explode on impact fireworks), tape it to the thumb of a glove. You now have ignition gloves. I am not responsible for what happens to your fingers afterward.
Trevor Schiavone it's likely, cooling metal quickly will cause the crystals of the metal to shrink and be very small, this means it is really really hard but also brittle
I think so. It would be nice if he did a new video comparing those 50/50's that were hardened by rapid cooling in water VS some that were cooled naturally and annealed afterwards. I think there would be a huge difference in strength.
The copper in the brass is the major cause for the brittle behavior. Like with any other alloy, the copper can improve the strength, but in doing so it also decreases toughness.
I tried making Aluminium bronze, after several failed attempts, i eventually heated aluminium way past its melting point, then adding in the copper which dissolved in easily, , i used a steel crucible but couldnt control the iron dissolution into the mix, what was liquid at this temperature i poured off, and this was a magnetic golden metal that i hammered out flat without any sign of cracking
But zinc IS a heavy metal... From Wikipedia: "Some heavy metals are either essential nutrients (typically iron, cobalt, and zinc)" You're also right, Zinc causes Metal Fume Fever
+Erik Lewis Haven't you learned not to believe everything you read on wiki yet? Fe, Zn are assuredly NOT "heavy" metals. Zn will give you flu-like symptoms, that rapidly pass when you aren't exposed. (Also, you quickly build up a tolerance to Zn exposure! Welder's flu is also called "Monday evening flu" because you're more likely to get it after a weekend away from the welder.)
If you had let them cool down by air they would have been stronger because the atoms would have mor time to arrange into a crystalline structure with bigger, more organized crystals
This is incorrect due to the fact of inter-metalic bonds, these two metals are not compatible. This makes them very brittle, although if it was cooled slowly it would be less brittle yet still very brittle.
I don't think solder would be the best source for tin because of all the other stuff in it. If you would use solder the best choice would probaply be lead free Sn-Ag-Cu as the Silver content is just about 3% wich would equate to somewhere in the 0.3 - 0.4 content in the bronze but he'd have to get non flux-cored one. Probaply easier to just get the Tin from ebay
@@thepizzaguy8477 well... they can, but not at normal temperatures... you can oxidize metals fairly easily, you can even evaporate or turn metal to plasma with enough heat....
@@thepizzaguy8477 zinc does, so dose magnesium, and aluminum can burn. But yeah copper is called a "noble metal" so copper doesn't burn or oxidize as easily as other metals.
when you mix dissimular metals in a crucible you have to stir them well while molting to get a thorough blend. try reacting the 50/50 blend after stirring. you might be surprised at the resulting alloy. great video
interesting, i was gonna comment that its brass, not bronze, but it seems like many alloys of copper are called "bronze" which is interesting considering that most standard aluminum is actually an alloy of aluminum and copper, named duralumin by the founder of the aluminum age hardening process. which technically composition wise is very similar to aluminum bronze.
The reason why the metal became so brittle is because you cooled it with water. This causes micro air pockets to form in the newly mixed material, which make it extremely brittle. I would implore you to do the same half and half mixture and then let it cool on the concrete till room temp. The same principle can be found in welding, where whenever you add new material (or the weld filament), when you cool it down with water the same thing happens. The weld becomes brittle, and can’t hold up as much weight.
The reason it shattered so easy doesn't have much to do with the metal more the fact that they are metals. While the aluminum is brittle, the reason it shattered so easily is because it was cooled down rapidly. This increases hardness (resistance to scratching) but increases brittleness (resistance to shattering). If it cooled down slowly, in air, in sand, etc. it would be less brittle but would also probably be less shiny
I dont think that is what happened here. If you take a look at the broken pieces you can see that the crystals are extremely large. Large crystals mean the alloy cooled down from liquid to solid very slow. Now iirc neither aluminium nor copper have a phase change below the melting temperature so cooling them fast after they solidified does not make any difference.
The rapid quenching with water tends to make metals a lot more brittle. The rate of cooling has a big effect on the way the crystalline structure forms and changes the metal properties a lot. That could make an interesting video, make the same mix of metal a few times, allow one to cool overnight, quench one in water, and quench one in liquid nitrogen. Then test how brittle they are.
I'm surprised he took so much time building this gas furnace and getting an actual crucible but not proper tongs to manipulate it. Rest in peace Grant. Your DIY science legacy lives on.
Yeah, I think you would be looking to suspend the metal in the glass structure, rather than blend them or make an alloy. Pretty sure glass is non-reactive and can only be decayed away. There are many examples of glass blowers using foreign particles to make designs, colourization, structure, etc. I think an ancient glass blowers used to blow finely ground particles into their pieces. Certainly for colouring, glass "alloys" are a possibility.
TheTiemotje They do in the process of making certain forms of glass where an ingot of tin I believe is melted down and the molten silica floats on the tin
Some crystal glasses use metal oxides from lead or zinc but you need temperatures way higher than 1000°C, which is enough to melt brass or copper, to properly combine the materials into glass. 1500°C is what you'd need to have at least. Other metal compounds are used to colour glass and lead glass is also used to shield from ionizing radiation. Molten metal probably wouldn't work though.

Wuchubuchu You certainly can melt fool gold it's melting point is about 100 degrees Celsius higher than coppers melting point . Fool Gold melts at around 1180 degrees Celsius 👍🏻
Quenching metals make them brittle. That's why tempering is needed afterwords. The reason smiths quench metal is because something brittle can be extremely sharp. But they temper afterwords because too brittle and it will lack durability. If you let them cool slowly I suspect the chances of them shattering upon being dropped would be reduced significantly.
This, if you JUST quench it in water, it's going to be EXTREMELY brittle, hence it shattering on the pavement, but if you temper it, say with a blowtorch or even just putting it in an oven for ages, it will help it gain some strength back.
Tiffany Quenching brass actually makes it more ductile afterwards. Reloaders do this when converting cases from something like a 20 ga. to .577/.450. Not all metals behave the same. :)
Lmfao they quench it to set the cystaline structure of the metal. It has nothing to do with sharpness. The reason its brittle is cause all the molecules are under stress, tempering reduces that stress.
quenching steel makes it brittle, while hot steel is ductile. quenching copper alloys makes them ductile, but hot copper alloys are very brittle. metal =/= metal.
You're both right. There are actually a bunch of different alloys that are 'bronze.' Some are just copper and tin, others add in other metals for different uses. Steel is the same way. If you just add carbon to iron you'll end up with a basic form of steel..... but if you add in other metals, like nickel, chromium or molybendium, you'll get steel with different properties. (Corrosion resistance, extra hardness, greater durability, etc.)
yeah bronze can be made using a variety of metals... infact aluminium bronze is made with copper and aluminium, has it's benefits over the traditional tin bronze... so grant pretty much made bronze in this video.. even though he used brass the zinc burnt off leaving copper.
tommy bernotas No you need special equipment to melt glass properly and safely. If he did that it would shatter and might even explode. If for some miracle of science it doesn't explode it would not be clear like regular glass you see everyday.
Aluminum and copper are the basis for 'non-sparking' tools. Called aluminum bronze, it has a soft golden color, is a little heavier than Al and is very corrosion resistant. The curiosity I have is this: what do these alloys do in terms of heat-conductivity? Copper is one of the best cheap metals for carrying heat, Al comes in a distant third. Silver is the best, but at current prices you won't see too many Sterling Silver heat-sinks. Sterling is about 97% Ag, 3% Cu by weight. Next week on 'This old guy rambling', we make a Silver heat-sink by melting down some un-circulated 1923-D Peace dollars with a 1943 copper penny or two. Work with what you have, I guess.
thats a nice question, if it was an alloy thermal conductivity and thermal expansion would be in between copper and aluminum, however thats not an alloy, copper aluminate forms at that temperature, in my opinion thermal cond. would decrease dramatically since the crystal structure and mech. properties resemble ceramics.
Would you be able to use the heat resistant fabric and wrap it around the crucible so you don't have to use those tongs? Great video! Keep up the great work!
he wouldnt explain what happens when metals mixing together then a person whois entire carrer is metal, also yea but it doesnt mean you NEED a top level foundry. its melting metal its not that difficult todo (probably could even use a magnifying glass stand to melt it)
but your still not getting the point, it's better when someone like him dose this stuff on his chanel, and it's a lot better for people to see how he dose stuff like this and at the same time he can show what metels he can melt using just those simple things
jake listen, there are plenty PLENTY of interesting metallurgy videos that go way more indepth then grant, sure he might give a little info but not near something a proffessional could tell you. heck even welders must know metallurgy to not tottally melt everything into a puddle , technically he could melt almost any metal (with highly heat resistant ones being the exception) just need enough airflow to fuel the fire
MOIPAH it would crack as soon as it comes into contact with liquid nitrogen.. Because of the temperature difference between the two materials and also it would become very brittle if it retains its shape somehow.. And would break the moment you press it even in between your fingers because of the porosity
The liquid nitrogen would vigorously boil and splatter molten alumium for several feet, not to mention the alumium would pop from thermal shock... so yeah not really something you'd want do
The LF effect would keep the explosion from being as bad as it could be, but it would indeed throw molten aluminum EVERYWHERE. Wear a lava suit or say goodbye to your face.
Plz do more metal foundry videos, and maybe you can use that 75℅ brass and 25℅ mixture and pour it into some casts of certain things like a ring or another Pokeball!
You'd get more consistent pours if you used a gravy ladle instead of pouring directly from the crucible. Also, the 50/50 alloy probably shattered because you cooled it quickly in water, introducing stress fractures, rather than slowly annealing it in the crucible.
I'm not sure how the processing is done but there is a new class of materials (I believe it's a type of polymer) coming out that are metallic glasses. They have some rather interesting properties (including massive kinetic absorption ability and the ability to be permanently magnetized while still being made into very unique shapes).
Traditional Crystal is a type of metallic glass made from glass and lead (18-40% lead oxide), there is also uranium glass (2-20% Uranium, very pretty green colour) that was popular between the 1940's and 1990's, and yes Uranium is a metal.
Fredrik actually that is wrong. I had a muffin pan which was made of aluminum unbeknownst to me. the pan failed, and caused my concrete driveway to crack and send molten aluminum into the nearby vacinity.
If you left the mixture to harden naturally, then it is expected that the lattice structure would be more developed and therefore the ingot would be much stronger. Great vid!!!
Well it would work but not for long. While tungsten has a high melting point it oxidizes very fast at way lower temperatures. So as soon as you get it glowing hot it will oxidize on contact with air and slowly crumble away. Because of that reason high temp metal crucibles are typically made from platinum even though Tungsten has an even higher melting point and is much cheaper.
graphite (carbon) has a melting point of 3500ºC, so even higher than tungsten. also, tungsten is very heavy so it wouldn't be practical compared to a graphite crucible
When I'm making muffins I simply keep a five gallon Home Depot bucket two thirds full of water and then tap the muffins directly into it. Keeping the water at that level prevents any hot water from splashing out when the muffins hit but still gives you enough water to keep them from melting through the plastic bottom - you can pick them up with your hand in less than five minutes. If you're making lots of muffins then you needn't fret with having dangerously hot muffins sitting around air cooling - just keep dumping them into the bucket and when you're finished for the day you can dump the water and now you've got a bucket full of completely cool muffins. Added bonus - they make a really neat sound when you dump them in.
FraznoFire That depends on your country. Davy spelled it alumium, then was and published in the official discovery as Aluminium. Young violated norms and decided take it upon himself to rename Davy's discovery as he liked -ium endings better (which also altered the pronunciation). Since this was discovered in 1812 when communications we're slow the aluminum spelling persisted in the US & Canada and aluminium persisted in British colonies. IUPAC indicates both are now valid and correct, and in official publicaions is almost 50/50.
Two things I hope you guys consider. After watching this video, please try melting copper and ton for bronze and please try gold plating. It looks fun to watch.
TjDolHaus86 No. Aluminum melts at 660C while glass melts at 1400C. I bet the foundry could still melt the glass though. My plaster/sand coated foundry has melted its walls a bit.

Aren't zinc fumes rather toxic? I know zinc fumes are the reason you are not supposed to weld galvanized steel.

Some crystal glasses use metal oxides from lead or zinc but you need temperatures way higher than 1000°C, which is enough to melt brass or copper, to properly combine the materials into glass. 1500°C is what you'd need to have at least.
Other metal compounds are used to colour glass and lead glass is also used to shield from ionizing radiation.

This, if you JUST quench it in water, it's going to be EXTREMELY brittle, hence it shattering on the pavement, but if you temper it, say with a blowtorch or even just putting it in an oven for ages, it will help it gain some strength back.
Tiffany Quenching brass actually makes it more ductile afterwards. Reloaders do this when converting cases from something like a 20 ga. to .577/.450.
Not all metals behave the same. :)
Robert Rodriguez yeah science
Lmfao they quench it to set the cystaline structure of the metal. It has nothing to do with sharpness. The reason its brittle is cause all the molecules are under stress, tempering reduces that stress.
quenching steel makes it brittle, while hot steel is ductile. quenching copper alloys makes them ductile, but hot copper alloys are very brittle. metal =/= metal.
Can you make homemade bronze with copper and tin
it's not just copper and tin, but also some nickel or zinc.
Dr. ZomGaming traditionally bronze is just copper and tin
You're both right. There are actually a bunch of different alloys that are 'bronze.' Some are just copper and tin, others add in other metals for different uses. Steel is the same way. If you just add carbon to iron you'll end up with a basic form of steel..... but if you add in other metals, like nickel, chromium or molybendium, you'll get steel with different properties. (Corrosion resistance, extra hardness, greater durability, etc.)
I see $25 coming ur way
yeah bronze can be made using a variety of metals... infact aluminium bronze is made with copper and aluminium, has it's benefits over the traditional tin bronze... so grant pretty much made bronze in this video.. even though he used brass the zinc burnt off leaving copper.
3:28 did anyone see the bug on his hand? also.. great work grant! love this video
hint for bug: look at his hand with a brass nugget in it 😂😂
"That's gorgeous! Better smash it!"
Thomas Tyrrell (Lenny face)
Avery Mc cool ( ͡° ͜ʖ ͡°)
Thomas Tyrrell techrax
+Bob Ross i get it
0:03 That made me cry Rest In Peace you will not be forgotten ❤️
Do mor videos like this! Where you mix different metals!
he should mix the two densest metals, Osmium and the protagonist of a harem anime!!!!
lol
Can I have the muffin tray?
To bake muffin?
Yesssss
**actually makes a new metal like a boss**
Bipbop *epic just like epic games’ epic game fork knife!!*
It's not a new metal
Take the broken glass container and make glass muffins???
Yes
tommy bernotas YES
tommy bernotas
YES
tommy bernotas No you need special equipment to melt glass properly and safely. If he did that it would shatter and might even explode. If for some miracle of science it doesn't explode it would not be clear like regular glass you see everyday.
Littlescotty 22 Party pooper! >:O
Aluminum and copper are the basis for 'non-sparking' tools.
Called aluminum bronze, it has a soft golden color, is a little heavier than Al and is very corrosion resistant.
The curiosity I have is this: what do these alloys do in terms of heat-conductivity?
Copper is one of the best cheap metals for carrying heat, Al comes in a distant third.
Silver is the best, but at current prices you won't see too many Sterling Silver heat-sinks.
Sterling is about 97% Ag, 3% Cu by weight.
Next week on 'This old guy rambling', we make a Silver heat-sink by melting down some un-circulated 1923-D Peace dollars with a 1943 copper penny or two.
Work with what you have, I guess.
Greg Gallacci sterling is 92.5 hence 925
thats a nice question, if it was an alloy thermal conductivity and thermal expansion would be in between copper and aluminum, however thats not an alloy, copper aluminate forms at that temperature, in my opinion thermal cond. would decrease dramatically since the crystal structure and mech. properties resemble ceramics.
alloys have lower thermal conductivity than pure metals
Wow. A plug.
Copper isn't cheap lol
You should TOTALLY do a colab with slowmo guys
Nah, he should just get his own cam
I love Grant's cheesy smile haha
Would you be able to use the heat resistant fabric and wrap it around the crucible so you don't have to use those tongs? Great video! Keep up the great work!
WhiteFox he could but then there is the chance of the molten metal dripping down and buring his gloves and possibly his hands
No because that would make the crucible insulated and thus, not able to heat up and melt the metals
make a mold of your own head!
Piggiey5000 No He Can 3D Print his Face And make a Mold (Silicone)
there are ways to cast a head, I believe myth busters did it a few times and I've had my just my face cast in paper machete in middle School
Piggiey5000 he can put his face in the sand and pour some molten Al in that hole
You can do a life cast look on tested channel
smeltwater that's why you put straws up your nose when you make head molds
don't heat your brass so hot just a few degrees above melting point and use sum flux.
jim stone he can't control the temp perfectly
He likes to breath in metal vapors and roach killer for flux... rip
Roach Killer is just Borax
his hot box has no temp controller like most electrical have. Thats why i prefer electrical over gas types
My daughter and I still love your videos 💖
Since I'm a mad person, why not mix molten metal with liquid nitrogen?
Grant you could turn the slag back in aluminum by electrolysis
Put LED diode in liquid nitrogen, it should change colour.
Rostislav Rega the D in LED stands for diode, so you have just put light emitting diode diode
joshua patterson Smartass. (Quite literally, I think it's a compliment in this context. xD)
joshua patterson :D thx, at least i know now
Rostislav Rega you're welcome
Your channel has inspired me to start looking for a job in a foundry.
5:41 me when i find a shiny rock
The 3 brass to one aluminum remind me of bismuth unpolished.
Yeah. It’s really pretty.
i dont think i've ever caught a video this early
Matt Eden Same
Nice to see you early Matt. Did you ring the bell for notifications?
I ringed yhe bell but I get sent here directly
i dit
Grant Thompson - "The King of Random"
sometimes theres a 7-9 minutes delay of notification..
I bet those are the kind of sunglasses Bono would wear if he became a magician.
do more of these types of videos but with different metels
like if u think he shuld
theres plenty of metallurgy videos out on youtube...
Keyshaun Spratley but he dose it a lot better and all of those other videos on RUclips are with a professional metel foundry
he wouldnt explain what happens when metals mixing together then a person whois entire carrer is metal, also yea but it doesnt mean you NEED a top level foundry. its melting metal its not that difficult todo (probably could even use a magnifying glass stand to melt it)
but your still not getting the point, it's better when someone like him dose this stuff on his chanel, and it's a lot better for people to see how he dose stuff like this and at the same time he can show what metels he can melt using just those simple things
jake listen, there are plenty PLENTY of interesting metallurgy videos that go way more indepth then grant, sure he might give a little info but not near something a proffessional could tell you. heck even welders must know metallurgy to not tottally melt everything into a puddle , technically he could melt almost any metal (with highly heat resistant ones being the exception) just need enough airflow to fuel the fire
Grant cast a metal Hand/glove that fit your Hand so you can CRUSH stuff in Slow Mo
Would be awesome !
A gauntlet?
TheZoukii123 Yeah that would be cool
YES!!!
You don't cast that kind of thing...
hmmm... maybe you can find a way to take advantage of the 50-50 mix's fragile property
comment ideas for the things you can do with it
Abrasives?
shattering metallic props for stageplay, acting, or films.
Grenade kinda Idea
Thermite
Is it just me or is the look of molten metal totally awesome?!?!
You made aluminium bronze with too high concentration of zinc.
What would happen if you put molten aluminum into liquid nitrogen?
MOIPAH it would crack as soon as it comes into contact with liquid nitrogen.. Because of the temperature difference between the two materials and also it would become very brittle if it retains its shape somehow.. And would break the moment you press it even in between your fingers because of the porosity
Arvind The Sharpshooter no he is saying MOLTEN aluminum like the liquid
The liquid nitrogen would vigorously boil and splatter molten alumium for several feet, not to mention the alumium would pop from thermal shock... so yeah not really something you'd want do
MOIPAH it would boil so fast it would explode
The LF effect would keep the explosion from being as bad as it could be, but it would indeed throw molten aluminum EVERYWHERE. Wear a lava suit or say goodbye to your face.
Not sure if this is possible but can you do Lava Vs. Liquid Nitrogen?
YES
RIGBONE2311 Lava is basically melted rock so I'm sure he could put some rocks in his furnace and get some nitrogen.
Since he has the electric furnace with carbon rods, he can make small amounts of lava.
RIGBONE2311 liquid nitro my only weakness
King of random: *has pool in yard*.
Also King of random: I brought this water from inside to cool the metal.
You
"That's pretty though..." - starts smashing it with a hammer. XD
The colors in the last ones are aluminum oxide crystals.
All i can think when watching this, is aluminium brass from the tinkers' construct mod for minecraft.
3 parts aluminium 1 part copper.
kris220b haha me too
kris220b Haha same
Bradley Hinton calm yourself, it's not that important that others are enjoying themselves even if you aren't
kris220b yas
kris220b totally
My teacher made us watch this for school and I normally wach you guys so this was very fun👍😀❤️
Year 2020
Plz do more metal foundry videos, and maybe you can use that 75℅ brass and 25℅ mixture and pour it into some casts of certain things like a ring or another Pokeball!
Oh lad, you were me favorite
You'd get more consistent pours if you used a gravy ladle instead of pouring directly from the crucible. Also, the 50/50 alloy probably shattered because you cooled it quickly in water, introducing stress fractures, rather than slowly annealing it in the crucible.
Some say love, it is a river, that drowns the tender reed. Thanks man.
What can you do with aluminum oxide once you've skimmed it off of the top of your molten aluminum?
Dan Sullivan I think he should make a video where he goes from one to the next
Grant Butler Aluminum oxide is rust. Thee isn't much use for it when forging or melting aluminum to my knowledge.
Thermite from the 50/50 mix? it looks easy to turn into powder.
I think it'd be really cool if he made a thermite video with his own aluminum oxide
I believe he has already, but I may be wrong.
you should make a device that allows you to pour it out more safely
melting glass and aluminum together what happens?
Glass would have chunks of alluminum embedded into it.
Or the glass would be broken.
I'm not sure how the processing is done but there is a new class of materials (I believe it's a type of polymer) coming out that are metallic glasses. They have some rather interesting properties (including massive kinetic absorption ability and the ability to be permanently magnetized while still being made into very unique shapes).
rushthezeppelin isn't the glass in welders masks a metallic glass?
Traditional Crystal is a type of metallic glass made from glass and lead (18-40% lead oxide), there is also uranium glass (2-20% Uranium, very pretty green colour) that was popular between the 1940's and 1990's, and yes Uranium is a metal.
You get transparent aluminum from Star Trek IV.
Hey Grant, the first aluminum alloy with copper ever invented was very brittle when rapidly cooled but very very tough when allowed to cool overnight
Hey Grant, how about mixing different ratios of copper and aluminum?
Hey could you use the metal foundery to make glass??
If the muffin pan can hold molten aluminum what is the muffin pan made of?
looks like steel and is most likely steel. Steel's melting point is almost double that of aluminum
steels melting point is 1500°C/2732°F
Fredrik actually that is wrong. I had a muffin pan which was made of aluminum unbeknownst to me. the pan failed, and caused my concrete driveway to crack and send molten aluminum into the nearby vacinity.
well that sounds terrifying. i hope you survived.
El Cabaro *face palms*
If you left the mixture to harden naturally, then it is expected that the lattice structure would be more developed and therefore the ingot would be much stronger. Great vid!!!
how do you clean the crucible after its coated in metal?
Ben .-. You get it hot enough to melt again.
you cant scrape out the sludge on the sides and get every bit?
You risk damaging your crucible by scraping it.
i just cant imagine it all coming off considering how some of it cools and films up right away
Ben .-. that is because the mouth of The Crucible is not as hot as the base
I can't belive it, this guy played with lava, yet he went out in paragliding
I know but littlest things can be dad
I’m an f1 fan OK!! Dad?
That's not lava that's metal there's a big difference
Ikr it sucks
Its not lava its molten aluminum and brass
Tungsten crucible, Grant. Do it, please. And like if you agree.
i don't know if that'll work, and isn't tungsten expensive? i mean for finished products of tungsten.
Jason Shaw it would work, tungsten has the highest melting point of all earth metals currently found, (3422°C)
Well it would work but not for long.
While tungsten has a high melting point it oxidizes very fast at way lower temperatures.
So as soon as you get it glowing hot it will oxidize on contact with air and slowly crumble away.
Because of that reason high temp metal crucibles are typically made from platinum even though Tungsten has an even higher melting point and is much cheaper.
graphite (carbon) has a melting point of 3500ºC, so even higher than tungsten. also, tungsten is very heavy so it wouldn't be practical compared to a graphite crucible
Boi, Carbon aka graphite has the highest melting point of all elements currently on the periodic table of the elements.... Ya dunce
When I'm making muffins I simply keep a five gallon Home Depot bucket two thirds full of water and then tap the muffins directly into it.
Keeping the water at that level prevents any hot water from splashing out when the muffins hit but still gives you enough water to keep them from melting through the plastic bottom - you can pick them up with your hand in less than five minutes.
If you're making lots of muffins then you needn't fret with having dangerously hot muffins sitting around air cooling - just keep dumping them into the bucket and when you're finished for the day you can dump the water and now you've got a bucket full of completely cool muffins.
Added bonus - they make a really neat sound when you dump them in.
Can you use a Vacuum or an Air Pump to blow out the insides of an egg?
What if you cooled the ingots in liquid nitrogen?
Anthony Herbert it would just crack
Anthony Herbert they would become powder metal and totally Brittle because the grain structure is completely weakened by sudden cooling..
If the zinc in the brass became that yellow stuff then wouldn't it just be aluminum and copper?
Not all of the zinc was being oxidized
He got back almost 2 muffins of metal in the 50/50 mixture, which means most of the zinc actually stayed in the metal.
*aluminium, not aluminum
in the states it's spelled aluminum
FraznoFire That depends on your country. Davy spelled it alumium, then was and published in the official discovery as Aluminium. Young violated norms and decided take it upon himself to rename Davy's discovery as he liked -ium endings better (which also altered the pronunciation). Since this was discovered in 1812 when communications we're slow the aluminum spelling persisted in the US & Canada and aluminium persisted in British colonies. IUPAC indicates both are now valid and correct, and in official publicaions is almost 50/50.
Two things I hope you guys consider. After watching this video, please try melting copper and ton for bronze and please try gold plating. It looks fun to watch.
I cant belive he is gone man
Take an ice cube on top of a new hot aluminum muffin
Mr.Burito it would make molten metal splatter everywhere
Only when it has cooled a little bit down, like solid
Mr.Burito it would just melt faster than usual
what would happen if you would put glass in the metal foundry would the glass melt?
Yes, glass melts before aluminium
TjDolHaus86 No. Aluminum melts at 660C while glass melts at 1400C. I bet the foundry could still melt the glass though. My plaster/sand coated foundry has melted its walls a bit.
Glass doesn't melt at 1400C, it's almost liquid at room temperature. Yes, glass is a strange material.
glass being "liquid at room temperature" is a common misconception. It is most definitely solid at room temperature unless your room is a furnace.
lordpouti you watch veritasium dont you..?
Its so satisfying when you were pouring the moltsn alluminumn into the muffin tray
Here's a thought: start pouring into the bun tin at the back and then work towards yourself. That way you won't risk setting your arm on fire!
Since the zinc burned off and formed Zinc Oxide wouldn’t you just be then mixing copper and aluminum?
Yes you would be, and would be creating alumibronze
Can't believe he's gone
it was great that you tested each mix resistance
