How To Make Synthetic Ruby In The Workshop

[@Nighthawkinlight]

Thanks so much for the channel shout out! Beautiful work!

[@IrishEagIe]

Could it be used in jewelery making?

[@OkNoBigDeal]

Kudos to you NHiL for giving ElementalMaker the recognition upfront. Subbed.

[@dwietr]

Nice results! I was wondering if similar results might be achievable by using inductive heating. While not sure if it would be possible with the raw materials or even with a premade ruby using an arc. But if possible, you might be able to get a more pure result, assuming this causes less carbon to leach into the ruby. Alternatively, would this method work, you might be able to draw a crystal from the molten puddle using a small slice of premade ruby. All aside, since this is based on a lot of assumptions and only a few reasonable concepts, this will probably fail miserably.

[@deborahstein]

Worked at a Company for 31 years that grew Large optical grade Sapphire,Ruby,Yag and others. The main process was the CZ method using an Iridium crucible and RF induction, the temperatures involved were in excess of 2100C Ruby Boules averaged 14 lbs, took about 14 days to produce and were fabricated into Lasers Yag temperatures were approximately 1960C and weighed about 5 lbs, took about 45 days on average, also for lasers Sapphire also 2100+C weighed as much as 60 lbs, had many uses including microchip substrate wafers It was a great job Jim

[@thethoughtemporium]

Dude you beat me to it! Been working on synthetic ruby for months now. Been working on replicating the verneuil process to make large boules, but this looks way easiesr. Still gonna keep working on it, but now I've got to try this method. Great job though, the ruby looks awesome. I've got a lapidary friend who I'll be having cut the rubies I make since as you found out trying to just sand it is a no go. Needs diamond disks to really do anything. I may try this with a tig torch and argon as there would be far less contamination and give a cleaner ruby that might even be laser worthy

[@Nighthawkinlight]

Ah sorry! Hate when that happens with what I'm working on. If it helps, these rubies are probably full of bubbles, and definitely nothing close to being a single crystal. If you can make them of a better quality that would definitely be worth while! Or just make sapphire of a different color and that's novel enough

[@thethoughtemporium]

@@Nighthawkinlight No worries it was a great video! Honestly, this mostly confirms some of what I'd been planning and tinkering with. I think I can still make a video which will add to the collection of knowledge rather than just being the same thing and build on it. Partly waiting for my friend to be out of an NDA so we can use a plasma torch to do this, beyond just using flames for the classic process, and we were going for as perfect ruby of a ruby as possible. Currently our issue was our torch was actually too good and liquefied large chunks of the kiln (which was made of proper fire brick). I think melting a fire brick is a solid achievement XD. So we're scaling that down and tightening it up the system. Also ya we've got all the stuff for doing a variety of colors, and were going to start on sapphires as soon as we got the base process working. I have a whole box of different oxides to try. Can do blue sapphire for sure and was also looking into some of the more exotic colors. We actually made some using a laser cutter to start with which I thought was neat.

[@Nemozoli]

@@Nighthawkinlight Could the bubbles be eliminated / a consistent crystal be created with a hydraulic press while heating the mixture?

[@Halloween111]

This is technically "Ruby Glass". It fluoresces, but its crystal structure is nearly non existent...the same as glass. This happens because it cools wayyyyy too fast like this. You need to melt the components then add a seed at just under it's melting point and seal the whole thing an insulated, pressurized, chamber so it will cool over months. The ruby and sapphire made by flame fusion are still pretty cool and still have some fun properties anyway. Good show!

[@justinw1765]

So it is far too amorphous to call a true ruby, which is far more crystalline in nature?

[@nills2gills811]

When you drop aluminum oxide powder thru vernieul thing and get micro rubies can you throw those micro rubies in the flux pressure temp chamber thing? Like a mix of the two different styles

[@kevinklatt7756]

Hey why don't you try using water when grinding your "Ruby" like lapidary uses. Sul. carbide is harder than corrundum and has been used for years to shape Ruby.

[@davidtreywq]

The “philosophers” stone is really just gold ultra purified (usually a finite powder like flour) and was cooked into bread and other foods for the rich. It’s not actually a stone like the one seen in Harry Potter and because of that movie people believe it’s a stone. But the philosophers stone was gold itself. Just gold. Nothing else. In order to get NOTHING but gold it’s gotta damn near be a powder

[@dw4353]

Full metal alchemist joke Me likey

[@kieranodea771]

If you have a metal foundry you can melt the rubies with the arc welder then place them in the foundry to cool down very slowly. This helps a lot for getting clearer rubies. They still won't be totally transparent but they look much much better !

[@Thunder0136]

Takes me back to high school close to 20 years ago. Made my own Ruby for a Ruby laser. Didn't use the arc welder though. Essentially made a small fire brick size electric furnace. The longer heat time allowed the impurities to separate a bit leaving almost crystal clear Ruby near the center.

[@alexandrevaliquette1941]

Impressive Bryan! How long roughly did it take to "bake" the powder into a ruby with your furnace?

[@Survivalist-of-war]

I have a devil-forge furnace and crucibles wonder if this would be possible to do in larger ammounts.

[@kimmy9695]

What temperature did you use?

[@Thunder0136]

@@kimmy9695 I don't have an exact temp. It was before temperature guns. I had used a coil type heating element the kind used in ceramics kilns. Had the entire thing buried in a pile of sand to further insulate. And since I powered the element by plugging it directly into 220 power. With no thermostatic control. It went until the element failed. Guessing about 10 hours. I left it sit untouched for a couple days as I didn't want any thermal shock to destroy any crystals if any were to form.

Sadly these rubies are completely amorphous - a mush of Al2O3:Cr crystals. To make single crystals, you need to implement the Czochralski process, and that is a LOT more complicated than just blasting a crucible with an arc welder. Alternatively the Verneuil method, but that's even more complicated to get right than Czochralski with modern hardware.

[@Spirit532]

@@danbhakta yeah, I prefer my Fifth Element reference to your explanation.

[@ProlificInvention]

Theodore Maiman's early laser used a powerful energy source (xenon lamp) to excite atoms in a synthetic ruby to higher energy levels. At a specific energy level, some atoms emitted particles of light called photons. These newly created photons struck other atoms, rapidly stimulating the emission of more identical photons and amplifying the light intensity. Maiman was able to continue this process of stimulated emission and amplification by placing a completely reflecting silver mirror on one end of the model and a partially reflecting silver mirror on the other. This setup enabled photons to bounce back and forth between the mirrors until they gained enough intensity to burst through the partially silvered end as a powerful, coherent, beam of light--the first working laser prototype.

Just a reminder, wood and lapidary shops all across the land play with diamond wheels and stones to sharpen, grind and polish. You can get really cheap diamond wheels that can be mounted in a drill or drill press to rough in and even move toward a polish on the stones. With a bit of playing, you could even use use diamond polishing pads intended for granite work and that are intended for use on angle grinders. I use a variable speed angle grinder so I can slow the grinder down. For the grinder, I rigged up a 1/8" inch hose, which connects to a regular law hose via a valve, which allows me to control the water flow. The water greatly extends the life of the diamond plates and pads. You could always buy a pad or three to dedicate to different compounds picked up from sites that sell rock polishing supplies.

[@claudehebert3131]

If you want to smooth or cut the ruby, buy some chinese diamond wheels. They're relatively cheap, can be used on a grinder (probably some models will fit a bench grinder too), and you might find you have a talent for stone cutting... Note: I bought some that came with a circular saw sharpener. They can sharpen tungsten carbide, so they should be ok for gemstone.

[@graysonsmith7031]

I wonder if letting it cool down slowly like glass would affect it in any way. My hope would be that it becomes clear, but I doubt that will happen.

[@SToNeOwNz]

I think the powder has too much air left in it also residual AlO Is gonna be troublesome, I would guess a pulse laser may be useful to make a clear sample as imperfections would be heated but the transparent crystal won't be affected as much.

[@buggsy5]

Nothing could be done to turn that mass into a pure ruby, crystal or otherwise. Primarily because the chromium in a ruby is there is trace amounts, not the massive 1%. It is unclear how much of the chromium oxide would be reduced to pure chromium that could migrate, under the right conditions, into a ruby crystal. Probably not much, since the only reducing agent present is the carbon crucible. I suspect the atmospheric exposure would tend to oxidize any chromium reduced by the carbon immediately back into chromium oxide. So maybe minute crystals of ruby will form, but most of the mass will remain a mixture of alumina and chromium oxide. Further, if you melt and cool a natural ruby crystal under those conditions, you will not end up with a ruby crystal. You will end up with a mixture similar to granite in structure. That is easy enough to verify. Just buy a cheap synthetic ruby (make sure it is not an imitation ruby), then melt and cool it in that graphite crucible. You will see the resulting mass is opaque and does not resemble a ruby in the least - except possibly for color.

I would love to see a cross-section to see how solid the inside of the ruby ingot is.

[@buggsy5]

It isn't, since it isn't really a ruby. At best it has some microscopic ruby crystals mixed in the amorphous mass, but nothing more.

[@quartqwertbudisgood]

Yeah, rubies made in this way don’t exhibit the same large lattice structure so the cut face would look pretty flat and dull. When these are faceted and polished they look pretty darn good though

[@locouk]

I know glass is microwaveable when it’s red hot, dose ruby have similar properties? It’d be a much purer way of producing a final product if this was the case.

[@SToNeOwNz]

The graphite crucible may not like the microwave but it may gain a diamond like coating on the other hand!

[@deaultusername]

silicon carbide crucible can be microwaved or heated by induction heater.

[@noahw4623]

I used to melt down aluminum cans in a home built foundry (nasty stuff, would not recommend even outdoors). It is not difficult to build a blast foundry, I made mine out of a plastic bucket, dirt, stove pipe, and an old hair dryer. I was making aluminum-bronzes, brass, all kinds of fun stuff. I don't see why this wouldn't work for making rubies as well, it certainly would be more economical than trying to make them in such a small crucible, and if you had an electric furnace instead you could probably grow a single crystal. It's my understanding the way this was done for silicon chips in the 70s was with a leaky bucket that slowly emptied allowing a weight to pull a seed crystal out of the molten materials. That'd get you much better clarity in your rubies The other thing to look into is a rock tumbler, just to get a nice finish on them and remove the roughness

[@vsssa1845]

hey is it possible to use wire coil wound around the crucible and use it as an induction heater, since graphite a conductor. maybe this way you can conrol temperature and also not contaminate the ruby with carbon from electrode.

[@untitled2792]

i saw another comment that mentioned this, probably does work

[@MsHojat]

I've always liked the look of opaque rubies. Still much of what I liked was how it still had a natural crystalline look to it. Maybe it could be emulated if this was faceted.

[@CaskStrength777]

I will throw this out there. It is now possible to machine solid ruby and Sapphire on normal cnc machines. A couple companies now, 6c and Zecha both make laser sharpened PCD (polycrystaline diamond) endmills that are hundreds of dollars for a single tool, but can actually mill solid ruby and Sapphire. If you had some serious money and somebody crazy enough to sacrifice the coolant filter on their machine, you could convince them to machine one of these into something for you. As a machinist I now find what is available to me in tooling absolutely crazy.

Out of all of the synthetic ruby videos that I've seen yours is by far the coolest one due to the large size of one of your rubies! It sucks that"ElementMaker" (who indeed does make pretty cool videos) was unsuccessful of creating rubies straight from metallic aluminum, that would've been cool! :(

[@michellebrowne9100]

I would 100% buy a pendant with one of these!

[@Regonix]

This should make in very low atmosphere (preferably in a vacuum chamber). Bonus, with a powerful laser you could encourage material mixing and thus make even more fine product.

[@trulyinfamous]

It seems that to make good clear rubies you need to keep it melted for a while. I'd imagine the bubbles trapped in it make it opaque or translucent.

[@eulemitbeule5426]

No, you need a uniform crystal to get a clear ruby. The product is just a bunch of microscopic crystals clumped together

[@trulyinfamous]

@@eulemitbeule5426 Wouldn't you get a uniform crystal from making it slowly? I thought bubbles would cause the opaqueness because my only experience is with glassmaking.

I would buy the purest reactants lab level, at smallest grain size, mix well, put in centrifugal pot, shoot a big laser while spinning (mirror at spin point) , high 'g', high temp, no impurities... equals optical quality ruby ? just kidding

Really want to try this now. I just wonder if you could produce sapphires with the same process but using a different contaminant?

Slap some iron or titanium oxide (for blue) in there instead of the chromium stuff and you should be good to go. Or at least I think it should work like that.

Nope, it is actually used as an abrasive in part because it is relatively tough and fracture resistant.

It is brittle but the forces required are pretty extreme - that’s why high end watches use them for the watch glass. Apple was going to use sapphire for phones but it cost twice as much as the glass.
