WOW. Wow wow wow. I'm so impressed. I mean, the lack of PPE scares me a little, nanoparticles are bad for you as is the TEOS, especially breathing it in. But your opal results are fricken amazing!!!!!!!!! I'm stunned. Awesome job.
I love opals I have mined and lab grown and the one you created is such high quality that I might actually give this a go, cant wait to see your future creations! Subbed.
I just sent my husband a list of things I need to make opal and his reaction was either "oh cool" or "uh oh". Haha either way I'm shopping for supplies!
That was a really neat trick and the final product looked good and easy to finish I think it has its place lots of people just want something that looks good so synthetics do fill a niche they look good costs is lower and can be made at home if you take both to a market your chances of a profitable day are greater very nice video
I’m imagining how cool it would be to do this as part of a chemistry class and then at the end of the semester every student has a lab opal pendant. Maybe working in collaboration with a metallurgy class to make the settings and shape the stones. Would be incredible
Stunning result! I love opals whether they’re mined in Australia, Ethiopia, Brazil, Mexico, U.S.A., etc., or even created in a lab. I don’t discriminate.
Wow that's insanely good. I came here after thoughtemporium's and Nighthawkinlight's videos and wanted to see if anyone else had given it a shot (happy to see them in the comments!). Didn't expect the phenomenal outcome. Hope you get the exposure you deserve. You guys should make a playlist of this cultivation series
I think some people are leaning more towards lab grown because at least you can know for certain where they're coming from, and that (hopefully) the employees aren't being exploited to create them. It just helps it so much more when they also come to be cheaper than natural stone. XD I would LOVE to create my own gemstones like this. I've been DYING to get my hands on raw lab grown stones to make D&D dice sets out of, and this video is scratching that itch for the fantasy. Thank you for sharing your process!
I would buy this. This look so much better that that oher syntetic opal i bought .. you did such an amazing job and it looks really good. I would set this in gold.
That piece is excellent, well done ,the colour play and patern is better than the any I have seen, one of the problems is the uniformed striations in synthetics ,buy that piece looks less uniformed ,really well done guys impressive stuff .
I recommend running your centrifuge on a lower setting, for a bit longer if necessary, to avoid vibration for the longevity of the machine and better results of sedimentation.
After some research on the sediment layers in Lightning Ridge, There are veins of coal in that area. The coal veins seem to be more prevalent in LR. This is the only source I can tell that would change the dynamics of LR opal to black. I am still doing more research and testing in my lab as well.
Thanks for showing the process! A few years ago i was looking for any info on how to grow opals and there was very little except for a few scientific papers, and vague information about Gilson opals. I might actually give this a go at some point
Wow, brilliant! What a process and the result is phenomenal!! Must take a lot of patience and organization to produce a video of a process over so much time, but the result was really amazing to see, thanks
Thanks for sharing your process and progress. Good thing there is plenty of opals naturally occurring to be mined still. It does take time and money with lots of people looking which is not the case now.
Definitely not a hobby for the impatient lol. What a beautiful creation. Even just seeing the first opalescent colours peeking out of the solution must be so exciting, and to be able to hold one in your hands & see the cabochon you created from scratch at the end is incredible! Truly fascinating. Thank you 😊

Brilliant video! I ended up building a supercritical drier and have dried and sintered one specimen so far. All of my research based off of the Gilson and Puzynin papers. I have several other specimens going currently and am at the stage of patience. I love your process; thank you for sharing. You have definitely given me a few things to think about and try next time I am working with TEOS.
It’s been 7 months since you posted this and you haven’t posted anything about it since. I want to see if you were successful at creating a black opal and if not why not. I would love to create one like yours turned out in this episode. No plastic, just pure opal. I would LOVE TO MAKE THAT! It’s beautiful!

Hi, I hope you read this... I have been trying to grow synthetic opal myself like 10 years back and experienced some difficulties you strangely did not seem to have, but the same difficulties are described in many academic papers and patents. Growing the nanospheres is a well-developed process and can be easily adapted to different sizes, as you have shown, but the real problems begin with drying the sediment. Virtually in every experiment I did, I had cracking and crazing of the dried nanosphere mass. In virtually every paper and patent like the gilson and kyocera ones, they needed to resort to supercritical CO2 drying methods, which I am sure you are aware of. However, in your video you show huge chunks of sediment dried without any cracks, and you simply state that you dried them, not going further into the techniques you used, but that really IS the interesting part. All the cooking in labware may be interesting to everybody who has never tried to make synthetic opal, but the drying technique is where it is at. Please, could you further go into your way of drying the opal without it cracking? Also, for the sintering step... how did you use a PTFE tube and heat it to more than 800°C? I guess it's C because I don't expect sintering to take place at much lower temperatures, glass melts at 1600C, so... but PTFE gives up at around 330C ... how come your tube did survive that? Also, Kyocera I think uses waterglass for filling up the porous voids for their synthetic opal. Besides these issues, I am really proud of your work and wish that you could share those techniques around drying the opal, since supercritical drying is the step where many will give up at, including myself. Congratulations!
When reading my last comment, I had an epiphany. Maybe you showed the secret: You mixed the different sized nanoparticles, which itched me when I first saw it and I found it odd, but maybe that's the secret. The smaller sized particles could maybe pack and arrange neatly in the voids not between bigger spheres, because that would be stupid, but in the voids between the photonic crystals, thus raising the silica content per volume and prevent cracking. I don't know it's just an idea
Hello! Thank you so much for reaching out, and for your thoughtful feedback and kind words about my work. I’m glad to hear from someone with hands-on experience, especially given the challenges you mentioned with drying and sintering synthetic opal. You’re absolutely correct; drying the nanospheres without cracking is often the most challenging step, and I’m aware of the complexities around supercritical CO2 drying mentioned in patents like Gilson’s and Kyocera’s. In the video, I touched on the basics, but I can see why you’d want more details. To achieve a stable, crack-free structure, I used a controlled, multi-stage drying process that gradually reduces humidity at low temperatures over an extended period. This allows for minimal internal stress build-up, which reduces the tendency for cracks. While not as rapid as supercritical drying, this method avoids the need for high-cost equipment and still yields large, stable pieces. As for the sintering step, the PTFE tube indeed wouldn’t survive temperatures above 330°C. To clarify, I use PTFE tubing only in the initial low-temperature phases, where it’s more about consolidating the structure rather than full sintering. For actual high-temperature sintering, I transfer the material to a different setup that can handle much higher temperatures, like ceramic or alumina containers. I also experimented with a few different filler materials, and while I didn’t use waterglass like Kyocera, I understand its appeal as a low-temperature void filler. Each method has its pros and cons, and I encourage experimentation here based on your equipment. Thank you again for reaching out, and for the support! Let me know if you’d like more specifics on any part of the process, and best of luck with your work.

i would realy like to do this but insted of making a smaller gemstone id make like bigger blocks or something. ive always had the dream of making a hilt for a knife out of opal or something like.that
Thanks so much for watching we have new video premieres every other Thurs 9pm EST LIVES every other Thurs with Giveaways Opals, T-shirt Opal Addict Gear etc. Hope to see you Thanks again!
Anyone know if colloidal silica used in the investment casting industry could be treated in a similar way? It could remove a lot of the risk involved with the TEOS stuff.
May you please share your calculations and initial ideas about using nano particles to sumulate the natural opal look? Were there other solutions you considered that would have different structure possibly appearing as something else besides striations?
In the synthesis of synthetic opal using nanoparticles to simulate the natural appearance of opal, the approach focuses primarily on the controlled deposition of silica nanoparticles. This mimics the natural layering and diffraction of light seen in real opal, which gives it its characteristic play of color. The calculations for such a synthesis would involve determining the optimal size and uniformity of the silica nanoparticles to achieve the desired refractive index and structural coloration. Other solutions could involve altering the deposition technique or using different materials. For instance, instead of strictly layering nanoparticles in a linear fashion to create striations, one could experiment with creating a more random or less uniform structure. This might involve using a matrix with varying refractive indices or introducing other elements like metal nanoparticles to influence the light diffraction differently. Such variations could potentially result in a material that exhibits a unique color play or even luminescent properties rather than mimicking the striated appearance of natural opal. These alternatives involve extensive experimentation and characterization to refine the materials and techniques needed to achieve the desired visual effects. Each approach offers a pathway to explore different aesthetic and structural outcomes, potentially.
Nice ! Nice ! Nice ! I think you should try adding the solution to some matrix . What is the matrix for the different kinds of opal ? Maybe you can make a rough black opal .
Here's an experiment that you might try. Go collect some see shells and let you mix settle onto that medium and then bake it. Id like to see how that turns out. I would even try cooking the shell with the mix then let it settle out and bake it.
That did turn out really pretty. I had no idea you coucl do this. Ive seen some fake opal but it wasn't made this way at all. I think it might have bee some kind of resin or something. This looks pretty close. You just need to get it to not be lines the way it is.. but hey its really pretty! Id wear something made this way. I was wondering when you took it out or the form and it looked like chalk how you would get it to be clear. Now I'm really interested in seeing you do a black opal. I wonder just how black you can get it. Thoses colors in black will be really pretty!
Hi sir, very aweome creation. Sir, how are different colours of nannosilicate are made? In this bieo only green nanno silicate is presented,but the other colors.. how its is made.. thanks .. awesome job..
Very Cool Thanks so much for watching we have new video premieres every other Thurs 9pm EST LIVES every other Thurs with Giveaways Opals, T-shirt Opal Addict Gear etc. Hope to see you Thanks again!
Thank you! I followed one of your earlier videos to make an "opaline liquid" (which was fub enough). Now I want me a subteribg furnace and ... (can't think of the word!) What holds the opal particles together in natural opal?
You need to make a larger piece to then slice it down the same direction as the colour, and polish that face instead of the top that you've done here. It would look so much more natural. You can see it when you hold this one after polishing. Or as a test cut this down the middle so you have 2 semicircle stones and polish the cut surface. I hope that makes sense
Thanks so much for watching we have new video premieres every other Thurs 9pm EST LIVES every other Thurs with Giveaways Opals, T-shirt Opal Addict Gear etc. Hope to see you Thanks again!
Your next video was not a continuation of this video series about synthesizing opal like you said it would be, and neither are any of the other videos you released...when are you going to show the results of the black opal experiment?
@@GlobalProspecting Maybe that's the secret sauce? I'm wondering how important that is. I have access to distilled de ionized water, but keeping a pH of 7 takes care. The NH4OH will change the pH obviously. I guess I can do my own research. I'm aware of some old TEOS that's going to be thrown out if I'm not already too late, so I may snatch it up and try something like this. Your results are incredible! Thanks again!
I have a theory that if you used harmonic frequencies during the sedimentary process is how you create different patterns solfeggio frequencies would be where I would start with a frequency generator this may extend the sedimentary process but I Believe it would be worth the payout
I will definitely look into it for sure New growing video coming soon! Here is the link to our latest video Thanks for watching ua-cam.com/video/jNGmGxNykqs/v-deo.html
Thank you very much for the video! Just one question regarding sintering: I suppose the mentioned numbers (825° for 24h) are in Celsius? Ah and also how long did you let the silicone mould samples settle?
WOW. Wow wow wow. I'm so impressed. I mean, the lack of PPE scares me a little, nanoparticles are bad for you as is the TEOS, especially breathing it in. But your opal results are fricken amazing!!!!!!!!! I'm stunned. Awesome job.
Didn't expect you to be here.
@@Radiata_Lionfish I mean he did like two videos on it so i kinda expected him here.
please do a collab!
I’m blown away with the results! Well done!!!
@leandrogoethals6599 the collab would be basically this video with some extra safety and maybe some new ideas to make even better stones
Big Complement from the OG!
Try sonicating the mix when pouring in the TEOS to get maybe violet.
Cool idea!!!
I love opals I have mined and lab grown and the one you created is such high quality that I might actually give this a go, cant wait to see your future creations! Subbed.
Thanka for watching appreciate it.
Amazing job growing opal you guys are the bomb
Thank You appreciate the support.
BEAUTIFUL
Thank you! 😊
I just sent my husband a list of things I need to make opal and his reaction was either "oh cool" or "uh oh". Haha either way I'm shopping for supplies!
Love it!!
I really excited for part two I know it would be great.
Wow, I can't believe I'm only stumbling on this video now. Really excellent job.
That was a really neat trick and the final product looked good and easy to finish I think it has its place lots of people just want something that looks good so synthetics do fill a niche they look good costs is lower and can be made at home if you take both to a market your chances of a profitable day are greater very nice video
I think you're missing some punctuation though...
That's the most beautiful synthetic opal I've seen! I can't wait for part 2!
SOON Thanks so much for watching here is a link to our latest VIDEO ua-cam.com/video/SR4PytUDGSw/v-deo.html
I’m imagining how cool it would be to do this as part of a chemistry class and then at the end of the semester every student has a lab opal pendant. Maybe working in collaboration with a metallurgy class to make the settings and shape the stones. Would be incredible
Stunning result! I love opals whether they’re mined in Australia, Ethiopia, Brazil, Mexico, U.S.A., etc., or even created in a lab. I don’t discriminate.
I'm with you 100% the more kinds you cut the better you get
Wow that's insanely good. I came here after thoughtemporium's and Nighthawkinlight's videos and wanted to see if anyone else had given it a shot (happy to see them in the comments!). Didn't expect the phenomenal outcome. Hope you get the exposure you deserve. You guys should make a playlist of this cultivation series
Thank you, thanks for, watching Great Idea very time consuming and costly but if the views pick up, we definitely will continue.
try leaning the containers while the opal solution is settling [including in the furnace] to create diagonal striations in the finished product..
Absolutely stunning so much vibrant colour cant wait to see a black one fantastic
Every time I watch this video I'm stunned at everything it takes to make that happen. It's absolutely amazing!!
Thanks Tim
This is the highest quality opal ive seen. Its even welo and synthetic thats amazing. I hope you make a shop soon the world needs these
Amazing video. Your lab create that opal was amazing. Great job very entertaining.
wow all that hard work really paid off.

cure them under heat and pressure when the silica solution is at varying consistencies
After some research on the sediment layers in Lightning Ridge, There are veins of coal in that area. The coal veins seem to be more prevalent in LR. This is the only source I can tell that would change the dynamics of LR opal to black. I am still doing more research and testing in my lab as well.

I also experimented with a few different filler materials, and while I didn’t use waterglass like Kyocera, I understand its appeal as a low-temperature void filler. Each method has its pros and cons, and I encourage experimentation here based on your equipment.
Thank you again for reaching out, and for the support! Let me know if you’d like more specifics on any part of the process, and best of luck with your work.
How much water do you add in the lat part ? When you mixed your opal solutions?
Opens are my favorite gem stone that was awesome thank dude

Do you have a video that shows all the equipment needed to be able to grow opals?
I can put on the list see if we can get that done Thanks for watching
Would cooking opal be a more relative term than growing?
Amazing
Teflon has a working thermal limit of ~500F. Not sure how it behaves at 800F but I suspect it releases some nasty gases.
i would realy like to do this but insted of making a smaller gemstone id make like bigger blocks or something. ive always had the dream of making a hilt for a knife out of opal or something like.that

I wonder if you can make it look more like natural white or crystal opal. I wonder what it looks like smoked like etheopian or a black dublet

Anyone know if colloidal silica used in the investment casting industry could be treated in a similar way? It could remove a lot of the risk involved with the TEOS stuff.

May you please share your calculations and initial ideas about using nano particles to sumulate the natural opal look? Were there other solutions you considered that would have different structure possibly appearing as something else besides striations?
In the synthesis of synthetic opal using nanoparticles to simulate the natural appearance of opal, the approach focuses primarily on the controlled deposition of silica nanoparticles. This mimics the natural layering and diffraction of light seen in real opal, which gives it its characteristic play of color. The calculations for such a synthesis would involve determining the optimal size and uniformity of the silica nanoparticles to achieve the desired refractive index and structural coloration.
Other solutions could involve altering the deposition technique or using different materials. For instance, instead of strictly layering nanoparticles in a linear fashion to create striations, one could experiment with creating a more random or less uniform structure. This might involve using a matrix with varying refractive indices or introducing other elements like metal nanoparticles to influence the light diffraction differently. Such variations could potentially result in a material that exhibits a unique color play or even luminescent properties rather than mimicking the striated appearance of natural opal.
These alternatives involve extensive experimentation and characterization to refine the materials and techniques needed to achieve the desired visual effects. Each approach offers a pathway to explore different aesthetic and structural outcomes, potentially.
I wonder if you can layer it very thinly on top of the other to create a more natural effect

Nice ! Nice ! Nice ! I think you should try adding the solution to some matrix .
What is the matrix for the different kinds of opal ?
Maybe you can make a rough black opal .
will give it a try great idea Thanks so much for watching here is a link to our latest VIDEO ua-cam.com/video/SR4PytUDGSw/v-deo.html
Here's an experiment that you might try. Go collect some see shells and let you mix settle onto that medium and then bake it.
Id like to see how that turns out.
I would even try cooking the shell with the mix then let it settle out and bake it.
Great Idea Will give it a try
That did turn out really pretty. I had no idea you coucl do this. Ive seen some fake opal but it wasn't made this way at all. I think it might have bee some kind of resin or something. This looks pretty close. You just need to get it to not be lines the way it is.. but hey its really pretty! Id wear something made this way. I was wondering when you took it out or the form and it looked like chalk how you would get it to be clear. Now I'm really interested in seeing you do a black opal. I wonder just how black you can get it. Thoses colors in black will be really pretty!
Yup, "Imitation" opal is inferior to "Synthetic" opal.

Hi sir, very aweome creation. Sir, how are different colours of nannosilicate are made? In this bieo only green nanno silicate is presented,but the other colors.. how its is made.. thanks .. awesome job..

OUTSTANDING!!!
Very Cool Thanks so much for watching we have new video premieres every other Thurs 9pm EST LIVES every other Thurs with Giveaways Opals, T-shirt Opal Addict Gear etc. Hope to see you Thanks again!
Thank you!
I followed one of your earlier videos to make an "opaline liquid" (which was fub enough).
Now I want me a subteribg furnace and ... (can't think of the word!)
What holds the opal particles together in natural opal?
Thanks so much for watching here is a link to our latest VIDEO ua-cam.com/video/cnH4wePOnA4/v-deo.htmlsi=UXhpiPSEExHIkkXo
Absolutely beautiful but definitely doesn't beat real opal that's millions of years in the making. Still looks nice. Thanks for sharing ☺️
Thanks for watching appreciate it new video every Thursday 9 Pm EST USA
Did you make a series yet on growing opals?
In the works Thanks so much for watching here is a link to our latest VIDEO ua-cam.com/video/SR4PytUDGSw/v-deo.html
Very cool
You need to make a larger piece to then slice it down the same direction as the colour, and polish that face instead of the top that you've done here.
It would look so much more natural. You can see it when you hold this one after polishing. Or as a test cut this down the middle so you have 2 semicircle stones and polish the cut surface.
I hope that makes sense
Will try that for sure.
Looks better than most real Opal. Amazing work.

How did you heat your PTFE reactor liner up to those temperatures when its melting point is only 372 degrees C?
It's melting point is just over 600 F it was taken out
Your next video was not a continuation of this video series about synthesizing opal like you said it would be, and neither are any of the other videos you released...when are you going to show the results of the black opal experiment?
Not sure yet
That's a truly amazing opal you grew. It got prettier as you cut and polished it. You must be over the moon about how it turned out, congratulations!
That was great....

Great job! wow. When you say pH balanced water, what do you mean? Is it DI water or have things been added to adjust the pH? Thank you!
PH Has Been Balanced PH 7
@@GlobalProspecting Maybe that's the secret sauce? I'm wondering how important that is. I have access to distilled de ionized water, but keeping a pH of 7 takes care. The NH4OH will change the pH obviously. I guess I can do my own research.
I'm aware of some old TEOS that's going to be thrown out if I'm not already too late, so I may snatch it up and try something like this. Your results are incredible! Thanks again!
Is it possible to add a little cremation ashes to this process.
That could be done for sure super great idea
Do you think you could make one for me?
I’m rather intrigued by this concept.
I have a theory that if you used harmonic frequencies during the sedimentary process is how you create different patterns solfeggio frequencies would be where I would start with a frequency generator this may extend the sedimentary process but I Believe it would be worth the payout
I will definitely look into it for sure New growing video coming soon! Here is the link to our latest video Thanks for watching ua-cam.com/video/jNGmGxNykqs/v-deo.html

Thank you very much for the video! Just one question regarding sintering: I suppose the mentioned numbers (825° for 24h) are in Celsius? Ah and also how long did you let the silicone mould samples settle?
