I came to youtube to see a pizza recipe now I'm watching this. we never know the way our life is going to lead us to
The real mystery is how did the pizza turn out? - Kae
Always remember to ware safety glasses when throwing experimental super heated materials into experimental molds. I talk out of experience. Some times you get unexpected reactions when your melted substance hits your mold. If I didn't follow these safety protocols, I would be blind right now. Always beware the explosive reaction.
i love how it is crude
like the sawblade on top of the melter pot, the floor literally made of dirt, everything looks so badass
That must be the most badass intro I have ever seen. Keep up the metal working its awesome.
very interesting video....now i want to start melting stuff for my channel!! thanks for posting!
The salt acts like flux to strip iron oxide off the cast iron, which makes the salt black when it solidifies. If you had a ceramic crucible and mold, you could probably get it to be clear or white.
DOUBLE DONE WITH THIS VIDEO
Melting point of salt is 1,474°F or 801°C depending on your temp measure.
Glass has a melting point of 2552°F or ~1400°C.
I think it is going black because the sodium which is an alkali metal is reacting to the water in the air and it is oxidizing.
I would also becareful when melting salt since normal table salt is NaCl you are turning the Na(sodium) into a liquid metal but the Cl(Chlorine) might be escaping and i think it is general knowledge that Chlorine is toxic
+IIGrayfoxII We were doing this in a extremely open and ventilated area. However it is good to be careful.
+IIGrayfoxII I'm pretty sure you can only separate the two elements via electrolysis on the molten or near molten product.
+Devils Advocate That's what I have heard/read as well, that you need an electric current running through the molten salt to separate the sodium from the chlorine.
+Valentin Lance Keypoint is: to get Chlorine (Cl2) from Chloride (Cl-) the Cl- has to get rid of electrons and someone has to take them. This is usually done by electrolysis where you take electrons from the chloride on one electrode to turn it into chlorine, and you pump electrons in the sodium (Na+) to get elemental sodium (Na) at the other electrode.
You will not get elemental chlorine or elemental sodium by just smelting NaCl.
diskordianer Yes, that is what I was trying to get at, that you need two electrodes, running a current through molten (there is better conductivity that way and the salt becomes less stable), the current would pull electrons out of the salt, and the elements end up separating because the elections are what made them stick together in the first place.
I honestly did not know salt could melt. It never even crossed my mind.
+Gmd Gentry not wood
+danick danck it can under special circumstances like in a O2 depreciated environment at extremely high heat but it's almost impossible
What about fire?
+Zenaida Alejo Fire is just heat.. how can heat melt
+MyLonewolf25 Wood is not a compount. It's a mixture so it doesn't have a melting point. It turns to carbon and releases various volatiles like water, acetic acid, ammonia, some other nasty organic compounds, etc. Charcoal will then, at way higher temperatures, sublimate into carbon gas. It will not melt at normal atmospheric pressure.
That looks both fun and interesting at the same time!
Great video guys. very interesting seeing what happens when you melt salt for sure. keep up the great work.
Thanks!
Maybe the Iodine gave it some color once it burned? Try non iodized, i'd be curious to see that.
Carbon always cakes on hot surfaces. Its nothing to do with contaminants, you just have to keep the exposed face of the poured block oxygen deprived. Do this by keeping a cool flame on it while it hardens. Thats why people who pour gold bars put the cooling bars under jets of fire while the gold becomes barely solid enough to plonk into water.
+Abrahm Davis no actually...this isn't sodium, it's still just salt.
I like his sense of humor. =)
Not sure if someone has already said this, but I think the reason the salt is black is because it's cooling so rapidly it has no time to form the pretty crystals, and instead just makes some kind of salt obsidian.
"I have steady hands Doctor."
"Wanna bite?"
I'm subscribing because you're bloody funny
+Kate Herreid Thanks!
+What We Made any tips on getting coal started easily? I can get mine lit off but it will slowly go out after a while. thanks!
Kate Herreid same 😄
She's actually a 240lb hairy dude. So yes, yes you can...😞
OKAY you put salt.....you forgot pepper.
Thank you always wondered what molten salt look like.
The blue glass is called cobalt. It requires far more heat than normal glass to melt. If you want to melt glass go with a "flint" your normal everyday clear glass.
The words you're looking for are, "furnace," and, "crucible."
A smelter produces metal from ore.
minecraft knowledge 😂😂😂😂😂
+Mark McCormack Or Foundry? :P
+Eric that would be the workshop in which you found the furnace and crucible. :D
Try "kosher" or sea salt and see what happens. They have no iodine in them.
Great video. I love experimenting in my shop and plan to watch more of your videos.
+mr10man69 Yah these type of videos are a lot of fun to do every now and then. Kinda breaks up the normal shop routine. -Caleb
I would have never thought to try this but it's awesome that you guys did! I think that darkening might be the potassium Iodate (Iodized salt), it's stabilier, dextrose, or the calcium silicate that is frequently added to prevent caking showing up as a contaminant. The melting point of NaCl is 1474 degrees F. I can't believe you got it that hot!! (At that temperature, it seems to me that the dextrose should have been converted totally to water and carbon dioxide). Iodine is a black solid and purple gas so I am leaning towards the iodine contamination here. Awesome. :)
In ceramics salt is sometimes fumed in the kiln for a particular effect. The sodium reacts to the silica in the clay making glass and releases toxic chlorine gas. This is done anywhere between 2,381°F and as low as 1,641°F. I thought for sure that what you were doing would release toxic gas and leave you with a highly explosive chunk of sodium, but nothing so glamorous appears to have happened. The more i know the more i know that i know nothing.
the smarter I get, the dumber I feel :P
+Eric Cowan To get the sodium, from a salt melt, you have to pass electric current through it. You get chlorine gas at one electrode and sodium liquid at the other. Neither is something you want to be anywhere near, at any time! Think "unexploded bomb".
+Paul Langford example of this is a car battery.
+Janet Wilham Car battery got water in it. If you overcharge, you get hydrogen gas, which if in a confined space can cause an explosion. Chlorine gas is toxic, burns the lungs and kills you. Sodium metal is extremely reactive; if you drop it on water, you have a big problem with the hydrogen gas generated so quickly, but also if it touches you, it reacts fast enough that the heat melts it, and the effect on your skin is like napalm (guess where the "Na" comes from).
The black color in the salt us probably from the iodine in the salt oxidizing.
It looks delicious in that metal cup, like papaya juice or something like that.
working in a plant where salt cake was run through a smelter, I know for a first hand experience that salt that has reached the melting temperature it is very volatile and (can) explode in a sudden temperature change and, if it should strike you in your eyes, you are blind! SO,, you had better take precautions to protect your eyes
That iron man reference though
SVMTY0725 I thought it was decent myself - Caleb
just a friendly suggestion. wear a face shield when you smelt anything.
+Bri Hodson Yah we didn't own one before this vid we do now. -Caleb
mr mi5 in our newest video we got the budget to face shields. - Kae
+Bri Hodson
Not to mention a leather apron....
+Bri Hodson also realize that chlorine gas will be emitted from melting salt (NaCl)
+Bri Hodson He has his beard for protection...
I think people that have hobbies like this are the most content people in life. I'm not exactly looking forward to fighting traffic Monday morning while I go to my job (which I do actually quite enjoy) and timing my departure to the minute to avoid the returning traffic. Since I travel a crazy amount for work, I don't have a steady place to develop of hobby like this. But I'm thinking I really need to take stock of my life.
The thing about time is running out!
You can spend it, but you cant keep it. Once it's gone you can never get it back. Spend it wisely get a hobby and call it your life.
"it looks like a really red cake"... " wanna bite?" lol
hook the molten salt up to some electrodes and youll be able to extract pure sodium
Mmmmmm, smells like *falls over*
that intro is so euphoric
Chef Vortivask We can all agree on that. -Kae
What We Made m'lady
+Chef Vortivask First video I have watched of this channel. I thought he was going to trigger a massive explosion while just slowly walking away like a bad-ass.
Devils Advocate If we had the budget that would be #1 on the list of things to do. -Kae
+Devils Advocate i thought so too lol
Intro gets me every time xD
The reddish to purple color is due to using iodized salt. The elemental Iodine is
vaporizing. Pure salt (SaCl) will turn grey when it solidifies after being molten.
glass will melt at about 2100-2400 degrees - for that kind of glass.
+Scott Veirs
I used to work in a glass factory and you are correct 2400 F but they add some sort of lyme for breaking down the recycle glass. I used to work for King Seely Thermos some people did not know that there thermos bottles were made of glass. The thing I get is 'what? Have no clue to what it was'
@James Parker
2400 Farenheit, not Celsius . That's around 1315 C°.
Also, glass becomes increasingly soft with temperature. What's considered melting temperature is higher than what's needed for it to become softer and malleable, so a bottle could flatten down cooler than that. (Flowing glass vs just malleable glass).
You should google "molten salt reactor". Different materials, but a very good idea nonetheless.
Thanks!
+What We Made +FfejTball Was thinking the same thing. There's a super interesting documentary on that reactor from the 60's plus that guy from the TED talks.
Chefs "season" black steel pans by heating salt in them. It draws any impurities and moisture out of the surface of the metal, so as it cools, you can replace that with oil which then gets trapped in the surface, making them non-stick.
I just think that intro is pretty amazing
try poring molten salt into water it will surpirse you
+SyN Ambros Oh really? ua-cam.com/video/lreob7RYhpM/v-deo.html ;)
Oh Sorry I dident know you allredy did that
No problemo.
should i delete the message
or something im honored that you noticed me Thank You
+SyN Ambros No you're fine, maybe someone will see the comment and they will go watch the video, so it's all good :)
It's called a crucible.
+John Doe Oh, so that's what a crucible is. What does that have to do with the Puritan story about the Salem Witch Trials?
+carultch I don't know what does it have to to with the Salem Witch Trials? I was referring to the contraption that they are using to melt the glass and sodium.
John Doe
There's a story about the Salem Witch Trials called The Crucible. And I've always wondered #1 what a crucible is, and #2, what it has to do with the story.
carultch The Crucible is a 1953 play that was a fictitious dramatization partly based on the a Salem Witch Trials but a 'crucible' is also a noun describing a metal or ceramic pot used to melt glass and metals.
+John Doe But he is using a ladle
4:54 "i have steady hands doctor"
that was funny to me for some reason :/
I enjoyed that skit
Look up liquid salt nuclear reactors, Liquid salt is quite remarkable.
+roflcopterkklol I think it is actually the sodium-component of the salt that is liquid. Not the full compound salt.
carultch Nope the salt itself melts, Salt has a melting boiling temp of around 370C, the reason it would be great for nuclear reactors is if there was ever a breach in the system the salts will plug the breach, Because they need to be heated to over 300 degree to be liquid when the salts come back into contact with the air they solidify, if we were using liquid salt reactors the Japan melt down never would have happened.
+roflcopterkklol nuclear criticalities are self heating. meltdowns happen when things jam up and the nuclear rods can't be cooled be the water. come up with instant permanent ice, and you got yourself a billion dollar product to sell to governments around the world
+Yvette Zarate the point of liquid salt reactors is that the salts are much better at conducting the heat away from the fuel. Meltdowns happen not when things jam up, but when there is nothing taking heat away from the core, like cooling water.
+Kyle Cornwell Well Said.
When you say 'salt' I assume you mean sodium chloride....
Generally speaking, sodium chloride is acidic. This is due to the nature of the chloride ion, and it becomes more pronounced the higher the energy of the overall system. Molten sodium chloride is probably pretty acidic.
Silicon Dioxide forms a variety of complexes, but it does so under basic conditions. In fact, acidic conditions are noted for increasing the melting temperature, depending on the silicate that forms, so it's not too surprising that the glass failed to dissolve in the molten salt, despite it being hot enough purely by comparing melting temperatures.
You can actually get glass to dissolve into regular temperature water, but you have to use strong bases to do it. Sodium and Potassium silicate are relatively easy to get a hold of and are the product of dissolving glass into a strong hydroxide solution of potassium or sodium respectively. Sodium silicate is referred to as "Water Glass" and it's usefulness is hard to understate. Potassium silicate might actually be more useful, since glasses containing potassium are noted for their strength, but it's use isn't as well documented.
Molten salt is useful in it's own way though. Actually there's some interesting stuff you can do with salt and polycarbonate. Polycarbonate is considered more transparent then glass, allowing a wider range of light to pass through it unimpeded; if you combine this with a transparent salt, you can make lenses and optics that can see in different spectrums and stuff.
RhetteLawe
you're pretty much right on about the silicate chemistry. pure silica is also "water glass" as its totally water soluble as well. typical glass formulations are fluxed with sodium bicarbonate and limestone, to lower their melt point and increase their solubility resistance
RhetteLawe
though i do have to say there are quite a few formulae of clear glasses that produce far superior refractivity characteristics than polycarb , english leaded crystal and borosilicates such as old pyrex (new pyrex post sale of the brand is just dual tempered window glass no boric oxide in it at all) being two examples you might be familiar with.
The usefulness of polycarb as an optic lies in it's extreme transmission range. lead crystal glass, although they don't have physical flaws, don't transmit all wavelengths of light. Specifically, there are some infrared wavelengths that polycarbonate is good at transmitting, and specifically glass is bad at transmitting. This is why you have to use a salt and plastic cover like polycarbonate to make focusing lenses.
Infrared lasers are cheap atm, so having the ability to make opts for them might be something useful.
true i was referring purely to the lack of those physical flaws, you are of course right in terms of transmitted wavelengths. are you familiar with methods of making things like synthetic opals? theres a ton of neat stuff that can be done artistically.
Josh S
I have not specifically messed with trying to make synthetic opal, but I am aware of several methods.
It depends largely on what aspect of the real opal you're trying to go with. Emulating the natural product is tedious, purely through the components given in the natural product, but there's things out there that can work. Dichroic glass mostly.
That would be called a hand crank forge. Way cool!
so was that a salty burn then?
It's not English it's the scientifically proper term. Aluminium
stupid shit
+TheMDoesGaming for knowing science?
+ForeverOfTheStars lol
wait so it's pronounced aluminium in every language?
Kalani Castro this guy is a fucking idiot, dont listen to him.
American or not, Its Aluminium.
Aluminium not aloomeenoom aluminium
its aluminum dumbass
+Elevate sounds +TheProCactus Both are correct.
L4v31d3m pro isnt correct, hes calling it aluminium. Its called aluminum, not with an "I" between the "n" and "u".
+Elevate sounds
Spanish: aluminio
Portuguese: alumínio
Brit English: aluminium
Dutch: aluminium
Turkish: alüminyum
Italian: alluminio
French: aluminium
German: aluminium
Swedish: aluminium
see the trend?
then came an american and say: Nooo i can't say that, it's too hard. aluminum is bettah!
This was strangely satisfying to me...
why so many dislikes?
you are disliking others video and you are dislike king
Wear something better than jeans for this. A hot welding rod will burn through work pants and flesh in a fraction of a second, I can't even imagine the horrors a drop of molten salt or aluminium would cause if it landed on you.
ouch
hey boys, look up the murphy firebucket, its purpose built for melting glass but i use it sometimes as a mini forge also. keep it melty!!!
if you put two electrodes in the molten salt you can separate Sodium from the salt. its a metal that catches fire/ blow up when you through it in water.
Literally just finished watching Iron Man! You already got a like for being interesting but if I could do it again I would just for that quote! XD
Blue .Falcon Thanks for the like! I couldn't have asked for a better moment for the quote though. - Caleb
its black/brown because of iron/rust that got into the salt. it will also turn black if it touches charcoal/carbon. it absorbs impurities really well, makes it hard to keep clean.
I had this same idea though, I wanted to mix glass and salt, to make a salty cup or something xD imagine salty glass?
Cool. If you melted pure salt (not iodized) it should come out white. Molten salt is very reactive. Tiny impurities (like copper ions) can make it change color.
I meltet and castet Salt once. In the end it was perfect white
I agree with the previous suggestion and also advise you to wear safety footwear and keep clear of the timber when pouring molten liquid into it.
Molten liquid....!??
You mean... something like WATER !??? 😂😈
If you don't want to contaminate your salt, poor a pile and use a propane torch. Heat it from the top. You will have a clean melted salt, which look likes water except it glows red.
I have done it with salt (NaCl mp 801 °C) and I have done it with Na2CO3 (mp = ~850 °C)
Nice video as always, always great to see a "youngster" not having his face buried in a video game. Sincerely brother, were safety glasses and a face shield. When you stuck your nose down there at the end of the vid I was hoping that the hardening didn't out run the off gassing. I burnt the crap out of my face once with lead, only 800 degrees, it beyond sucked, learn from my mistake.
"...and then you will never taste anything again"
your wrong...
he will taste pain...MWAHAHA...MWAHAHHAHAHAHA...
MEAHAHAHHAHAHAHAHAHHAHAHAHAAHAAAAAAHAAAAAAAA!!!
XD
I have steady hands my love!😂✋🏻😭💖😉
Peachy Annie I bet 😘😘
Did you use just straight salt and nothing else?
Thanks 4 Sharing Guys !!!
You could pull a single crystal out of the salt. You need a small salt crytal and dip it into the molten salt and then pull it up slowly it should form a clean crystal without fractions.
Yes
What temperature are you working?
exactly what I was thinking salt is corrosive so it probably remove some of the material from the flask
That was pretty kewl
Super cool!
melted salt is used for heat treating and blackoxsiside finishing..
I love how you all did this just because you were curious about what would happen. =]
pfft a beanie in 80 degree weather. this Guy!
I was watching "Gojira - Liquid Fire" and I was brought here, video checks out, Liquid Fire!
Pretty much would feel the same
I used to work at an aero space company that kept a large "salt bath" going 24/7 which was molten salt. Used for heat treating certain things I believe. Now the reason I mention this is because they were always highly worried that the salt would get too hot and go exothermic and EXPLODE...They paid to have an electrician and plumber on duty 24/7 365 days a year due to the extreme danger involved with that and some other stuff...anyway I know diddly about such things but thought that maybe it is something that someone might want to look into befor melting much salt??
this is awesome
Cool experiment :) Perhaps if you melted the glass and salt in seperate ladels you could see if the liquid forms are miscable. Pity the glass didn't play the game...
Is that ladle cast iron? I guess I'll be needing to see what the melting temps for salt and sand and find a metal with a higher melting point.
i think forge is the best word for your mineral melting contraption
There is also some iodine in the salt too if it's iodize salt.
cool, very original
what a strang conversation going on in the background
Create a 1000 year old earth battery. zinc in cup then salt in a cup like you did then copper in cup take out of the cups then smelter weld them tall , volts come when soaked battery in any water liquid from.
Try shaping / like glass blowing
Could you please smelt salt and sand together and show me what it looks like when pouring and after its cooled?
Wow. An American, of his own volition, saying 'aluminium'. Music to my ears. :-)
Hand grinders and blowers are precious. guard it with your life.
+Larkinchance Yah I really love my rivet forge. -Caleb
subbed for the Intro
Here on youtube, in Spanish, there are videos showing people making outdoor clay ovens (think wood fired pizza ovens) that incorporate lots of broken glass and salt underneath the floor. I'm wondering if the molten salt and glass are an insulator to keep the floor of the oven cooler or hotter. Also if that were inside a homemade thermos would it keep the contents hotter longer? What are your thoughts?
i wonder how solid it is maybe next time you guys should try to crack it open to see the inside :o
tell me which carbon used in making the glass seeds beads
Had you passed an electric current through the salt it would have broken the molecules down into base elements NA & CL. The sodium is fun to play with but the chlorine gas will kill so make sure to use some sort of powered ventilation system to keep it well away from people. Also the the sodium Will react violently with the moisture in the air so it should be keepers in oil.
Makes blue FIRE
The vessel that holds the molten metal is called a crucible
Did you try cutting and polishing it? I wonder if the colour goes all the way through?
Cool video! I was hoping you weren't going to burn yourself @4:16 and theeeen, plumber's crack lol.
You boys will be up for a "Darwin Award" before you know it!
looks like one of those Saratoga springs water bottles.
Where that wood was smoking so heavily, it actually would have caught fire, if it was given a spark. It's not actually the solid wood that burns; it's the vapors (other than water) coming off of the wood when heated enough, that are fueling the flame.
I'd also suggest that you find a material with a sufficiently high melting point (above the temperature of your furnace), that also will reflect/insulate heat better, and use that as lining for the burn chamber of your furnace. There's something called "refractory" that is designed for this purpose, but some really lightweight clay might work better than metal, if you can't get any refractory. I'm still researching ways to fire clay, but so far it seems tricky, so do the research beforehand, if you want to fire your own clay. I wonder if mixing the lighter-weight ashes with clay would produce a more insulating clay. Anyway, most important tip for firing clay: make absolutely sure it's completely super dry, before firing.
And now that I think of it, you probably wouldn't need whole, undamaged clay for lining your furnace with. Just some broken bits held together with some cement or something, forming a wall. (Use gloves when handling cement though. I think I've heard that it has a component that can eat away at skin. Lime, or Lye, or something.) Sorry if I'm just volunteering a bunch of knowledge you don't care about, by the way. I just kinda get excited about building things like this.
