Will probably look like a maroon color cut rock. They do not look pure enough to to have gem quality crystalline structure. Still, it would be cool to see.
@@lucusloc Well they're obviously going to be amorphous due to the process and heat/cool times, but it would still be neat to see one faceted, but I want to see it used as a tool as I don't know anything about how rugged amorphous ruby is.
@@AtlasReburdened Polycrystalline, not amorphous. You don't get amorphous aluminum oxide unless you do some really unique deposition/growth methods. At high temperatures, the speed of nucleation is just too high.
Well, that was easy. Might give it a shot myself. I wonder what it would take to get to gem quality. Maybe just a longer heating period and slow cool down.
I would absolutely love to see your take on the process! From the research I did it looks to take a pretty long time, on the order of weeks to months to grow a clear ruby boule, but I'm still going to keep on trying 👍.
I may very well do that. If I make a video I will be sure to source your channel heavily and push some traffic your way. Are you still using 95/5 ratio of Al2O3 to Cr2O3? I saw that in one of your earlier videos. Did you pull that ratio out of thin air or did it come from some source on making synthetic rubies?
@@Nighthawkinlight NightHawkInLight I appreciate that so much. In this case I used a 99% Al2O3 to 1% Cr2O3 mixture. Most research I found stated between 0.5% to 5% chromium doping is used for ruby synthesis.

I worked in a foundry that had an Arc Furnace, the electrodes were about the size of your legs. When they fired her up, the lights on the block would dim. She sounded so awesome firing.
What about using a conical graphite crucible as one of the electrodes with the stick one close to it surrounded by the mixture? Maybe that way you can melt all it into one bead?
@@ElementalMaker Wow, I really appreciate the amount of time and money you put in your videos even before publishing them! But even after the time I am following you I did not know you have a B channel! Can you please write the name? Greetings from Bavaria!
@@scarakus But if it is not in use but plugged in and on the inductive current is so high that they actually will try to spin in reverse, as the lagging current reacting with the voltage coil turns the eddy current disk backwards. Most meters however have a one way clutch on the one bearing to prevent this, so it simply stops moving.
I can vividly remember when I was little running to the meter when my da was welding (a little 220V welder) to see the disc spinning every time he welded something, especially in 1992 when he built the house fence with steel tubes.
That is so cool! I remember my uncle telling me when I was young that some lady figured out how to make rubies and that it was some secret...now I've come full circle and seen them being made with my own eyes. Thanks for sharing this
I have a synthetic sapphire, a cherished ten cent reminder from a former job. They get cut into wafers and electronic circuits are built on them. Rubies are and emeralds are chemically nearly the same, except rubies have a trace of chrome, and sapphires have a bit of iron (or titanium). Awesome video. I want to see you make some diamonds. You already have the carbon...
If you sub the chromium out for vanadium, you should be able to make sapphires that can be confused with alexandrite instead. (purple/violet) Iron and titanium together can be used to try and make blue sapphires. You can also try and use the two mixes piled together (but not mixed [think two piles, pushed together]) to try and make a color shifting sapphire. Just using iron can make green to yellow sapphire, and using iron and chromium together should make orange sapphire. Also, using just the aluminium oxide on its own should make colorless corundum, which is apparently a popular alternative for diamonds in jewelry. (for marketing reasons, they'll typically call it "colorless sapphire" instead of "corundum" :P)
Your video was recommended to me as an amateur chemist. Your results are impressive especially considering this was your first attempt. I’d love to see one of those rubies in person. Please stay safe so you can post more videos!
I wonder if these could be used as seeder crystals for hydrothermal synthesis? Would the lower quality structure negatively impact the growth? Like what would the new crystal look like?
I think if you're zoomed in, you're actually less likely to burn the camera's sensor. It's the same amount of light (given by the area of the camera lens), but distributed over a larger part of the sensor.
Holy crap that was a beautiful sight to see. As a gemstone lover since I was a kid (especially ruby) I don’t even care if I was too late for the contest or whatever, just watching solid ruby form in real-time made my day!
YES! I have been so excited for this! God damn thats a lot of heat. I'd love to see alternate ratios of powder mixed to see what happens or possibly add in other chemicals. I really hope to win one of these rubies.
I just tried this with aluminum oxide (i'm waiting for the green stuff to arrive) Anyways, how would an arc torch operate in a vacuum chamber? I wonder if it would pull out the bubbles while forcing a super slow cool down time
Commercial synthetic ruby is made by dissolving aluminum oxide in lead oxide and lowering temp until ruby starts to crystalize. Can get big single crystals by "pulling" slowly. Thought you'd want to know how its really done.
Yeah lol Basically pure energy being released. For the 1st time I saw power lines arch out last week because thousands of birds landed on them and make the lines jump and short out very impressive arch probably about 10 feet.
@@SeanBZA haha not sure i didn't see it but some of my coworkers saw some fall to the ground lol ot happens when they all jump off the lines at the same time so not very many get hit.
What if you preheated the crucible from beneath/sides prior to, and/or during the extreme arc event. Preheating the crucible, for tolerance of a sudden extreme, may sustain your crucibles.
As much as I love classic whiteboard-style chemistry channels nothing compares to the empirical, elbows deep, backyard experiments. Looking forward to future projects. I heard rubies are used in water jet cutters.
My father had this exact arc welder in his basement workshop, from which he build his own drill rig. While I was impressed by the brightness of the arc everytime he told me not to look at it (and I did, by all rights I should be blind) I had no idea it could have been used to make friggin' RUBIES!!! I have to ask him now if he still has the bloody thing or got rid of it.
This man will flood the black market with these fake rubys and become a war lord of greenland Edit: By fake i mean man made, didnt think i needed to explain that
When you've sifted out the rubies, is the rest of the green mix valid to try and reuse? Also, what methods would you recommend for heating the rubies longer and cooling them more slowly?
Wow, I cant believe it is that simple! I definitely have to try this. Just need to buy some oxides, big carbon electrodes and maybe one electrode holder.
Have you considered using a TIG welding torch? Maybe also using graphite crucible. TIG would give you far more control and perhaps the argon shielding gas might be beneficial?
I had the same thought, though possible problem is the Ar blowing the powder around. What he might want to try is taking a refractory brick and carving a trough & lining it with thin cermic fiber, or diy a ceramic coating. The trough shape would minimize having to fidget the rods inside a cup, giving a bit more control & possibly being able to make a ruby the size of a 'baby carrot'
I’d like to see how these rubies compair to the ones my grandfather made, I was passed down a small bag full of synthetic rubies made by him, (largest one is about an 1/.5/.5 inches in size) i’d love to cut one of these myself or see how Cody’sLab &/or send it to nilered or AVE
This is very educational. I can now make rubies, but definitely I cannot afford to buy the materials and the equipment necessary to make these synthetic rubies. Thank you so much for this post. I really love rubies, especially when they are already cut and polished.
Assuming you could facet it smooth enough that it would make a good finish. I'm not sure how inserts are usually made, but I know that a little ding here or there can make a difference... Still, I'd be really interested to see it :D
Curiosity always gets me so these maybe ideas for another time. I was wondering how cooling speed would effect making these? The other is maybe a binder, helping to keep the chemicals from sputtering?
Well if they did, I would see it as an insult, cause what does a biological stinger do? It inserts once and sprays its load, so I guess it's a good thing they don't call it that
keep eye out for more welders like that!! those old ones are so esay to fix!! the brands on the outside may not be the same but the parts inside unbolt and others bolt in!! i have one that was made in the 60s!! 1960s and still works!!
I came over from Night Hawk’s channel and he used a carbon crucible that he drilled out to form his rubies. I’m going to try this out myself one of these days. Great videos from both of you.
I wonder how well those'd work as lasing crystals. They might have too much carbon in them, but with some cutting and polishing they could produce some coherent light. To get really clean crystals you'd probably have to use tungsten rods to avoid any carbon form getting inside (though I'm not sure if the tungsten would react with the aluminum oxide or chromium)
I'd love to see a video comparing the properties of these to natural rubies. Also a video on how this ruby creating method actually works. And a video one what some potential uses for these would be.
Bummer deal dude I was all excited and getting ready to jump into this and then you put up a disclaimer looks like it's off limits for me thank you for the great video
If I remember correctly, King of Random had a lid on his firebrick and that seemed to hold the heat. I wonder if a "heat soak" would give a clearer stone...?
I use those carbon rods for glassblowing. Just fyi you can just peel that copper right off. just get the edge up where the carbon is showing and the you can peel it in a spiral all the way off if you want. I peel some of in order to produce different types of tools
Something you might try is adding some inert gas to the mix, ark under some Aragon so you dont have oxides in your stone. All you would have to do is run a plastic tube into or just over your little bowl. Might stop the dark spots.
can we mix fe2o3 + al +cr2o3 to get ruby ? in theory fe2o3 +al is a thermit reaction and should produce al2o3+fe and a lot of heat . al2o3 + cr2o3+heat=ruby
Ruby, or the elements that make up ruby, vaporizes, ( change of state from liquid to gas), at average of 4000°F. Hydrogen burns a flame at around that temperature. Back off your flame. The flame will have to burn for about 20 minutes to properly congeal and burn out the impurities. Hydrogen fluoride is what is used to clean rubies up.
Here's a thought. Put a heavy wire coil around it and pass high current ac when you do that. Maybe Justin line with the electrodes. The hope is that when the alumina melts, it becomes conductive and absorbs even more energy from the field maybe leading to a runaway melting.
Im already digging that we essentially have the same interests. So i have tried this exact method as well and also got kinda grayish coloration on the outside. Also assumed it was from the carbon rods. (I pulled my carbon rods from old big 6v batteries). One problem i had though was mostly ending up with a ruby shell where the inside didnt fully heat up. Ive since experimented with using my tig welder for the arc to remove the carbon aspect, and i stopped seeing the dark gray discoloration. As for the big rubies ending up only forming a shell, i made a jig out of stainless steel. Basically two 1" rods as a tester with bowls cut in either end where i could put the AlO and CrO mix inside and pack it into a ball. Heat the mixture up with the arc and once it was glowing super hot put a weight on top of the other rod to add pressure and keep heating the rods to help cool the mix more slowly. This did produce more fully dense larger rubies but far from what id call jewelry worthy stones. I havent polished any of them yet to really see how theyd turn out. Id like to revisit the setup and try and find a better way to induce the heat into the dies while keeping pressure on them at all times. Kinda like how they form PCD.
Though now im thinking if you put the 2 powders in a small carbon graphite shotglass and touch those to each end of it will it heat the whole inside of it hot enough to make larger rubys
Have you thought of getting a graphite crucible also do you think you could find a way to combine the homemade arc welder with a graphite crucible to have a less hands on process for creating the rubies like having each of the leads mounted inside it so all you would need to do is power it on and pour the mixture in ?
Sweet. Been wanting to make higher quality rubies by setting up a dual hho setup. Allow the ruby to stay heated longer... phone glass takes like 6 months. Would be cool to see how well that arc welder did though!
I was watching a video about making a plasma device. It has to be in a vacuum. It would be very interesting if you would try and make a ruby in this environment, I wonder how an experiment could be set up to see how a ruby made in that environment would turn out. Could an emerald or sapphire be made in the same way? Fascinating! Have you tried to polish any of the stones?
Nighthawkenlight did this with your permission of course, and that is how I found you! So glad I did! Those rubies are unbelievable to me! I would take one to a jeweler and see if they think it is up to par for cutting a d polishing! How cool would it be to tell people that you made the ruby in the piece of jewelry they are admiring! 👍👍😁
how about throwing those nuggets into a rock tumbler and see what kind of a polish they'd take? Do those carbon rods get eaten away by the arc, looks like the ends are wearing away.
Thinking about aluminum and arc heating, isn't bauxite processed with electrical arcs? might be an interesting video. I seem to recall the biggest impediment to mass production of aluminum was the heat needed to processes it and arc furnaces made it possible. I may be mixing up my industrial history though.
Hey, I remember stumbling across your HHO video a while back. Glad you see you're still not burning down your shop! Those carbon rods are crazy hot on a big welder like that.
What if you tried making a ceramic tube/ trough and coursed the current between the two anodes using the particulate as a connection point? Would that yield larger synthetic rubies similar to how fulgerite is made?
Very nice. I saw one called Gadolinium Aluminum Gallium Garnet with a very bright yellow glow. It is used as a scintillator, a crystal grown for its insanely strong fluorescence.
Great vid mate, thanks for the comments about the uk 🇬🇧 but as a citizen I'd probably differ in my opinion. Anyway just thought I'd say you could use a car battery... pos wire goes to a metal plate submerge the metal plate into a large container about 25ltrs of water secure the metal plate on one side of the container put another metal plate secured at the other side of the container. The water act like a massive capacitor type thing. Then put another wire from the second plate to a carbon Rob and a wire from your other battery terminal to a carbon rod, hey presto a extremely dangerous way of doing the same thing... the carbon in the Ruby could be reduced by performing the burn in a zero oxygen environment 🤔,, the arc in oxygen is actually producing flash graphene !! Which is mixed into your lovely Ruby... Great stuff
How about making a hollow in an insulating fire brick and melting in there instead. Less likely to crack. You could even make some sort of glaze as a barrier
Hey idea for your ruby printer! You should check out conventional laser cutters with built in blow out for the mirror. You could probably modify a head to feed the powder. And run a pattern multiple times. But at this point you might as well do the conventional sls. Or, if lasers dont like reflective ruby, you could use an electron gun. But now you have vacuum chambers...
as far as your arc furnace idea goes, if you enclose your crucible within a chamber capable of pulling a reasonable vacuum, which would be good for also removing gaseous by products and vacuums lower the boiling point of liquids too, but more importantly, you will have a far easier time of creating a stable arc, and it will use less voltage to strike , I know normally one has to just touch the electrodes to kick start the vaporization of the electrodes to to be able to start the arc, but it should be easier in a partial vacuum as it has less dielectric resistance than air at S.T.P. does...might also increase the purity of your product ?
I think zooming in would be less stressful for the sensor, since the same amount of radiation is distributed over a larger area. the total amount landing on the sensor only depends on distance and aperture of the camera.

keep eye out for more welders like that!! those old ones are so esay to fix!! the brands on the outside may not be the same but the parts inside unbolt and others bolt in!! i have one that was made in the 60s!! 1960s and still works!!
Good to know and yes they kept them simple and robust back then. Not much to go wrong, and when it does it doesn't take a phd in rocket surgery.
I live near the legendary Cleveland, Ohio, USA
Perfect pronunciation, by the way!
I came over from Night Hawk’s channel and he used a carbon crucible that he drilled out to form his rubies. I’m going to try this out myself one of these days. Great videos from both of you.
The king of random lives on inside us all🥺
I wonder how well those'd work as lasing crystals. They might have too much carbon in them, but with some cutting and polishing they could produce some coherent light.
To get really clean crystals you'd probably have to use tungsten rods to avoid any carbon form getting inside (though I'm not sure if the tungsten would react with the aluminum oxide or chromium)
If I watched this after the pub, I would swear it was AVE.
yeah! I would say it is him. Ave, that is.
Yes! It is Ave.
Yup, Ave, green mat gave it away.
@@mitch1632 yea the green mat gave it away
I'd love to see a video comparing the properties of these to natural rubies.
Also a video on how this ruby creating method actually works.
And a video one what some potential uses for these would be.
Bummer deal dude I was all excited and getting ready to jump into this and then you put up a disclaimer looks like it's off limits for me thank you for the great video
You had me going for a second there 😁
I wonder if you can heat up the powder with a regular propane torch to as hot as possible then quickly stick it in a microwave.
I swear this guy sounds like AVE :P
I thought it was AvE at first.
His counter looks like an homage to him.
9:10 How would you pre-heat the crucible? Do you just chuck it in the oven at a few hundred degrees for a while? Or is there a specific method?
NightHawkInLight bring me here. You are awesome!
They usually use disc wetsanders to grind facets
Holy Shit Counter: Off the scale
Whether they're gem quality or not it would be cool to see how the look cut. This is awesome man
I've got an order for a pair of slippers from a certain "Dorothy"?
That home made arc welder is also a lichtenburge machine. You can use it for fractal wood burning and make lightning in wood
If I remember correctly, King of Random had a lid on his firebrick and that seemed to hold the heat. I wonder if a "heat soak" would give a clearer stone...?
I use those carbon rods for glassblowing. Just fyi you can just peel that copper right off. just get the edge up where the carbon is showing and the you can peel it in a spiral all the way off if you want. I peel some of in order to produce different types of tools
I tried peeling as that's worked for me with brands in the past, but these ones were damn near impossible to peel. Dissolution was easier with these
Wonder if it would be possible to shape that to make a 3d Printer nozzle. That would be interesting to find out.
Something you might try is adding some inert gas to the mix, ark under some Aragon so you dont have oxides in your stone. All you would have to do is run a plastic tube into or just over your little bowl. Might stop the dark spots.
can we mix fe2o3 + al +cr2o3 to get ruby ?
in theory fe2o3 +al is a thermit reaction and should produce al2o3+fe and a lot of heat .
al2o3 + cr2o3+heat=ruby
Ruby, or the elements that make up ruby, vaporizes, ( change of state from liquid to gas), at average of 4000°F.
Hydrogen burns a flame at around that temperature.
Back off your flame.
The flame will have to burn for about 20 minutes to properly congeal and burn out the impurities.
Hydrogen fluoride is what is used to clean rubies up.
The carbon rods are called carbon arc rods for a carbon arc cutter. You can get them at almost any welding supply store.
Here's a thought. Put a heavy wire coil around it and pass high current ac when you do that. Maybe Justin line with the electrodes. The hope is that when the alumina melts, it becomes conductive and absorbs even more energy from the field maybe leading to a runaway melting.
I wonder if the powder was set on a mold you know something that the liquid would set into while cooling and take that shape?
How large are all the tiny rubies in the ring that fluoresced after the first try? I was thinking of inlaying them into a bowl using epoxy resin...
Im already digging that we essentially have the same interests. So i have tried this exact method as well and also got kinda grayish coloration on the outside. Also assumed it was from the carbon rods. (I pulled my carbon rods from old big 6v batteries). One problem i had though was mostly ending up with a ruby shell where the inside didnt fully heat up.
Ive since experimented with using my tig welder for the arc to remove the carbon aspect, and i stopped seeing the dark gray discoloration. As for the big rubies ending up only forming a shell, i made a jig out of stainless steel. Basically two 1" rods as a tester with bowls cut in either end where i could put the AlO and CrO mix inside and pack it into a ball. Heat the mixture up with the arc and once it was glowing super hot put a weight on top of the other rod to add pressure and keep heating the rods to help cool the mix more slowly. This did produce more fully dense larger rubies but far from what id call jewelry worthy stones. I havent polished any of them yet to really see how theyd turn out. Id like to revisit the setup and try and find a better way to induce the heat into the dies while keeping pressure on them at all times. Kinda like how they form PCD.
Though now im thinking if you put the 2 powders in a small carbon graphite shotglass and touch those to each end of it will it heat the whole inside of it hot enough to make larger rubys
Have you thought of getting a graphite crucible also do you think you could find a way to combine the homemade arc welder with a graphite crucible to have a less hands on process for creating the rubies like having each of the leads mounted inside it so all you would need to do is power it on and pour the mixture in ?
Sweet. Been wanting to make higher quality rubies by setting up a dual hho setup. Allow the ruby to stay heated longer... phone glass takes like 6 months. Would be cool to see how well that arc welder did though!
I was watching a video about making a plasma device. It has to be in a vacuum. It would be very interesting if you would try and make a ruby in this environment, I wonder how an experiment could be set up to see how a ruby made in that environment would turn out. Could an emerald or sapphire be made in the same way? Fascinating! Have you tried to polish any of the stones?
Nighthawkenlight did this with your permission of course, and that is how I found you! So glad I did! Those rubies are unbelievable to me! I would take one to a jeweler and see if they think it is up to par for cutting a d polishing! How cool would it be to tell people that you made the ruby in the piece of jewelry they are admiring! 👍👍😁
how about throwing those nuggets into a rock tumbler and see what kind of a polish they'd take? Do those carbon rods get eaten away by the arc, looks like the ends are wearing away.
Thinking about aluminum and arc heating, isn't bauxite processed with electrical arcs? might be an interesting video.
I seem to recall the biggest impediment to mass production of aluminum was the heat needed to processes it and arc furnaces made it possible. I may be mixing up my industrial history though.
Now I want to know what ruby can be used for besides jewelry and nozzles for 3d printers
Hey, I remember stumbling across your HHO video a while back. Glad you see you're still not burning down your shop! Those carbon rods are crazy hot on a big welder like that.
Have you thought of using an induction melter for a cleaner melt?
What if you tried making a ceramic tube/ trough and coursed the current between the two anodes using the particulate as a connection point? Would that yield larger synthetic rubies similar to how fulgerite is made?
Very nice. I saw one called Gadolinium Aluminum Gallium Garnet with a very bright yellow glow. It is used as a scintillator, a crystal grown for its insanely strong fluorescence.
Great vid mate, thanks for the comments about the uk 🇬🇧 but as a citizen I'd probably differ in my opinion. Anyway just thought I'd say you could use a car battery... pos wire goes to a metal plate submerge the metal plate into a large container about 25ltrs of water secure the metal plate on one side of the container put another metal plate secured at the other side of the container. The water act like a massive capacitor type thing. Then put another wire from the second plate to a carbon Rob and a wire from your other battery terminal to a carbon rod, hey presto a extremely dangerous way of doing the same thing... the carbon in the Ruby could be reduced by performing the burn in a zero oxygen environment 🤔,, the arc in oxygen is actually producing flash graphene !! Which is mixed into your lovely Ruby... Great stuff
Need ones large enough to cut into dice.
That would be awesome 👍
I wonder if you used a graphite crucible would you be able to heat the entire contents more evenly to produce even larger ones?
Is there a way to cool it slowly? Maybe you could make a large single crystal if it cooled slowly.
This is nuts. It may be far off but making a solid rod of ruby and faceting two ends to make laser would be a fun long term project
How about making a hollow in an insulating fire brick and melting in there instead. Less likely to crack. You could even make some sort of glaze as a barrier
Hey idea for your ruby printer! You should check out conventional laser cutters with built in blow out for the mirror. You could probably modify a head to feed the powder. And run a pattern multiple times. But at this point you might as well do the conventional sls.
Or, if lasers dont like reflective ruby, you could use an electron gun. But now you have vacuum chambers...
as far as your arc furnace idea goes, if you enclose your crucible within a chamber capable of pulling a reasonable vacuum, which would be good for also removing gaseous by products and vacuums lower the boiling point of liquids too, but more importantly, you will have a far easier time of creating a stable arc, and it will use less voltage to strike , I know normally one has to just touch the electrodes to kick start the vaporization of the electrodes to to be able to start the arc, but it should be easier in a partial vacuum as it has less dielectric resistance than air at S.T.P. does...might also increase the purity of your product ?
Arcs don't really arc in a vacuum my dude
Do you think you could try to shape or just cut an edge and polish a corner of one? Just curious to see what that would do.
I think zooming in would be less stressful for the sensor, since the same amount of radiation is distributed over a larger area. the total amount landing on the sensor only depends on distance and aperture of the camera.
could you hit it with a torch to keep it hot and cool it with just nitrogen?
