Opal is easily one of the most beautiful gem stones and surprisingly it is also quite easy to grow synthetically. Unlike other gems which are solid crystals, opal is made of silica nanoparticles which have to be stacked together in just the right way to produce their magnificent colors. By growing silica nanoparticles of the right size, synthetic opal can be grown that looks just as amazing as the real thing.

But to avoid that vertical banding in synthetic opals. When you dry it over months you want the container to tilt along the vertical axis by around 5-15 degrees over 4-7 days as it settles. You can also have it Roll around the axis slowly over the same time.
That's a really clever idea!

No way! I spent a long time looking into synthetic opal production some years ago and never was able to uncover the secretive process. I've got an opalized fossil collection myself. Man this is great. Thank you

Now it's your job to figure out how to stop the tiger stripes. Can't be much harder than when you figured out starlight!!
Synthetic gems are always interesting
I've found a Russian patent about an inductrial production process for making opals. They let regular quartz grow in an autoclave, and then they heat-treat it to let it develop microcracks, and those microcracks have the same diffraction effects as real opal.
So they make a big piece of ordinary quartz, then cut into small pieces. The pieces get covered in sand, and they get slowly heated up to 550°C. They mention 2 methods:
1) slowly heat it up with 10°/hour, keep it at 550° for 4 hours, and they let it cool at 10° per hour; in their testing this gave a failure rate (fractured gems) of 1%.
2) in their high volume runs they let it heat by 60°/hour, keep it at 550° for 15 hours, and let it cool at 60°/h; but that gives failure rates of up to 5%.
All the heat-treated gemstones become opalescent+white (even the fractured ones).
So *you could try this process yourself with store-bought quartz,* that should work out as far as I can tell... So they used quartz that was grown at 30-32MPa, 300°C in a solution of 7-10% NaCO3 and 0.5-1% NaOH. They say that this is the standard way for industrial quartz production.
If you succeed: put the opal into your batman projector, i'm curious to see how that will look.
Try stabilizing the opals by saturating them with Starbond Thin CA glue instead of epoxy resin. It's generally used with wood but it's water thin and will saturate the opal way better and will leave it with a high gloss finish just like resin. It's completely clear.
As a South Australian listening to you pronounce Coober Pedy is murdering my ears but thank you for mentioning us. It’s also pretty tragic that they’ve found fossils here that aren’t worth as much as their opal value so they get destroyed.

What about stabilizing resin?
editing to add this info: Stabilizing resin is *designed* to seep into porous things such as wood. Put them into a pressure chamber to help reduce bubbles and hopefully reduce breakage. I believe Peter Brown (since you mentioned him) has used it a small handful of times on his channel.
I was gonna mention this as well. Especially the pressure pot as opposed to vacuum since it penetrates more.
Most the synthetic opals I've found (since I LOVE opal and have been looking this stuff up for years) are usually just held together with resin.
You can even find companies that sort their products by % resin.

For resins, try Opticon. You actually soak the opal in part A for awhile, then add the hardener to the stone (not the part A). Look at Emerald treatment for hints, but you do cover some of it at the end. Pressure AND Vacuum are more ideal. Warmed part A make penetration better.
I appreciate this guy actually giving the answer!
opal might actually come in useful for data encryption. powdered opal, when shaken, moves around and glitters differently. if taken picture of and encoded into text, it might come in handy as an encryption key, which is the tool needed to encrypt and decrypt information.
I think lava lamps might be enough for now
@@InfestedSlab its so random though, and im pretty sure a 10cm2 box of opal powder will do the trick
Just use nail polish in a bottle. Got a topcoat full of iridescent hexagons of different sizes which when you shake/move it changes drastically. Though that one (Wizard Lizard by Colores de Carol) is perhaps a little too heavily packed to get it to change as easily as a less packed one. The base is quite thick. But still, that's easier & cheaper than getting a box of opal powder.
No
Synthetic opals are extremely popular in the high end glass market. Typically they're encased in a glass which magnifies the stone and makes them even more beautiful. They can also be crushed into dust and inlayed into the glass. It basically looks like the most incredible glitter you've ever seen.

I don’t know, “is a pretty rock” seems good enough for me.
At the start of the video, "ya, I wanna make myself an opal." At the end, "nope not for me" XD

Have you tried running some soundwaves through the container as it sets its pattern? Maybe the 7.83 hz that is supposed to be the Earth's frequency. It'd be interesting to see if you could dial in different patterns or stacking of the particles.
Man that's interesting. I wonder what would happen.
It would probably mess up the opals shiny construct. Sound is vibration, vibration is constant movement. Like he said the samples sat still for months n the one time he tried motion it turned into a white chunk. So sound probably wouldnt be the way to go but its worth a shot. Maybe some sort of low range sounds possibly.
Also i just thought this, if you put sound directly around with the sample at the center, i can imagine the molecules being pushed away from the walls concentraded to a center, possibly creating an interesting piece of opal.
@@ppierson4126Some sort of resonance frequency may well be the "trade secret" to avoiding the characteristic tiger striping...
Someone needs to try it and let me know. Cause the physics off applied heay and pressure arent nor have to be so extreme as most gems to grow. So besides heat n preassure, resonance is the only other idea i have. It may take some trial n error but i can say id deffiniely go for lower frequency. Lower frequency less vibration. High frequency and you got an earth quake turning the mix into that whitw not as pretty rock.
I feel like that non-tigerstripe pattern might have a mechanic solution, where during the setteling process the opal is disturbed ever so slightly to knock some of the structure and force it to stack in different ways. Just a theory, of course, but it does seem the most organic to me.
maybe allowing a thinner disk of opal to settle normally, manually breaking it into the right size grains, and putting it in another tube with the solution would work
@@ejynk considering how delicate the pellet supposedly is, that might be a little hard to achieve... but possible, none the less
@@ejynk Or maybe taking some other crystals, like the air dried bits and mixing them in as it settles?
@@mwater_moon2865 yeah. I suppose that might allow it to crystallize but I am neither motivated nor smart enough to recreate this experiment
I was wondering about this, or possibly siphoning the solution off after a while and replacing it with another "color" of the solution. Alternately, maybe putting an uneven surface at the bottom of the settling chamber, so they have different planes to stack against?

You deserve so much praise and recognition for your literal MONTHS of effort and beautiful results. EXCELLENT video, you did a great job!!
perhaps the best stabilizer may be a heat activated wood stabilizer. These are made for penetration and are low viscosity. However, the principle of vacuum stabilization presupposes that there are air pockets in the material which will be evacuated by inducing a vacuum. When the vacuum is released the stabilization fluid penetrates into these voids which previously held air. I suspect there will be minimal penetration into an opal pellet which holds no fractures or voids (aka centrifuge sample). Other ways of stabilization may involve the introduction of trace amounts of aluminum after the microspheres have formed and just before centrifugation. A kaolite clay solution could be centrifuged beforehand with the wet-but-decanted pellet left in place and the opal microsphere solution carefully layered on top before it is centrifuged. This may provide trace aluminum and magnesium as well as yield a flat pellet rather than a pointed one because the nose of the tube was prefilled. Final suggestion? Place the pellet in the center of a ball of clay, wrap that in a layer of cotton and place the whole of it in a ziplock bag and forget about it for a year. This will allow for very, very slow migration of water out of the opal as the ball loses water through the plastic. This is an old trick for high water content opal that crazes after being taken from the ground.

Thanks for the explanation about muscle cells in meat! I've seen that iridescence many times but I assumed they were salt crystals.
Fun fact: William Lawrence Bragg was born in Adelaide, South Australia. The main reason it's a "fun fact" is that South Australia supplies at least 80% of the world's supply (the rest of Australia supplies maybe 75% of the rest); it's nice to see the South Australian physicist (either him or his father) involved with explaining the gemstone so common to the state.

@sadi muntakim Yay! Artificial scarcity and inhumane mining practices!
The thing is, many gemstones (especially diamond) are a lot cheaper to get out of the earth than you end up paying for them. Because clearly "high quality" means it came from a f**king hole in the ground!
@sadi muntakim Exactly. I was being sarcastic earlier, mentioning "higher quality" since people (unfortunately) can't seem to escape this "natural is better" mentality.
The funny part is, I've seen a few ads for various diamond retailers, and the thing they're *mocking* with lab-grown diamonds is their size. The fact that people supposedly wouldn't accept this precious gemstone, just because they can't brag about "their amazing boyfriend" or some nonsense like that by simply wearing it near other people, really says a lot about advertising, and about people in general. That they only consider themselves valued or important when they have something that they *clearly* didn't actually get themselves, the product of a relationship which will most likely violently implode within a few years.
@sadi muntakim Gotta throw out the whole system that allows that to happen.
@sadi muntakim yep, and diamond sellers have huge reserves of diamonds that they bleed into the market very slowly in order to not affect the price.

"as the inversed opal has way more uses than just; is a pretty rock. Like energy storage, electrodes, etc." He said bored...
20:20 Hey! Resin artist here hope I'm not too late!
So to stabilize a piece of opal in resin you may want to invest in a pressure pot to force the resin into the pours of the stone. If it can take the pressure this process with two part epoxy may be your best bet!
Or for the UV resin you have- if the atone can't withstand the pressure pot; try soaking the opal overnight in UV resin in a dark black room then cure the next day. That way the thicker resin has time to become a puzzle piece.
*** Third option is catalyst epoxy. It creates its own heat while curing so I'm not sure how it will work for you. It's a very thin resin and has a quick curing time. But it could be a good experiment!
Loved the video and hope this helps ✌
Amazing, thanks for sharing!
that would crack the opal
😎👍
love it .....also always caeful with catalyst epoxys...not a resin artist but construction worker...andyou have to know material tolerances and how it will react TO the reaction taking place on it....either way great tips....gonna save these for later 👍
I am a resin artist also, and I use Liquids Diamonds, it's so thin. It's by The Epoxy Resin Store (don't forget the word "The" or you end up someplace different), I've never seen a resin so thin before and because of that so few bubbles in the end. But I have to wait for it to thicken for my wall art pieces.
I recall reading about a process that imitated the natural formation, filtering a silica solution through soil and passing a strong electrical current through it. As I recall, it took several months, so patience was required. Would be fun to experiment with different solutions and processes.

Never confuse formal EDU for intelligence.
One thing you want to try is stabilizing resin. Peter brown used it a few times to stabilize bread. It's a very thin resin that is heat set, so you place the porous object you want to make hard into the stabilizing resin, and then draw a vacuum to extract as much air as possible. Then under atmospheric pressure the resin is forced into the voids of the product, which is baked to cure the resin. It may be possible to place the uncured object into a pressure chamber which is then heated, to further drive penetration of the resin before curing.
this gave me a new appreciation of opal. ive never know it had the colorful properties, and being an October baby i was kind of disappointed as a kid when it looked like milk in rock form, turns out id just never seen it from the right angle

I know it's a little late but if you do more with this look up how turquoise is sealed. What is used for turquoise would probably work. Also there are many types of resin and epoxys available in woodworking and the boat stuff to look at. I think the turquoise sealer is the best option.
If you do end up getting a drying chamber like that I recommend renting some industrial space outside the city and maybe getting an engineer consultant to double check your numbers.
Just in case you create a bomb...
It might even be worth the money (though tbh I am not sure how expensive that would be, compared to homebuilding it) to pay to have it professionally manufactured. I dunno about you, but for me "not accidentally blowing myself up" has a pretty high value
@@zuthalsoraniz6764 its not actually hard to make these things reliably safe.
a professional engineer and manufacturer could build you a large pressure chamber that is no heavier than it needed to be. has the most convenient access system that is safe and doesn't waste materials or manufacturing time. but it will be expensive and hard to mod
a skilled amateur will build a smaller chamber, with thicker walls, just to be on the safe side, getting samples in and out will probably be harder but being so familiar with it it will be easier to modify for other projects.
Putting it in a hole in the ground is always a good choice.
One idea instead of using a vacuum chamber to pull the air out of the opals (as the opal may be hanging onto the air inside too well for the vacuum to be strong enough to pull it out through the resin) may be to use a pressure pot instead to compress the air inside so the resin can fill in the empty voids. It will still leave you with air in the opal, but it will be crushed down to the point where it probably will be unnoticeable.
Another idea which I just got while writing this was to pull the vacuum on the opal first, to pull the air out of it, then add the resin on top of the opal while under vacuum. This may require a device to hold a cup of resin in the chamber and tip it into the cup with the opal remotely. Once you open the chamber with the opal submerged still in liquid resin the resin should be pulled into the opal due to the pressure differential inside the opal compared to the atmosphere.
There are definitely thinner resins on the market that will help you in this task as well.
Your first idea with the pressure pot is on a good path. Using a thin resin and the pressure pot may be useful.
The second won't work very well. When you are pulling a vacuum on the resin, it doesn't release air trapped inside it. Instead, it is essentially boiling off the VOC's that are in the resin before any of the air can escape. At a later point you may finally be pulling any air within the opal out, which if you are letting the opal/resin cure under vacuum, the resin will have no force pushing/pulling it into the opal. Degassing then re-pressurizing as seen in the video just won't work due to the forces needed to move the resin.
He could try stabilizing with cactus juice stabilizer which is much thinner and is used under vacuum, but needs to be baked to cure it.
Until you release the external pressure and you stone explodes.
@@MGgoose1 I never said you should let it cure under vacuum, that's not a good idea. You should dunk the opal in resin under vacuum but release the vacuum while the resin is still liquid to be pulled into the opal from the pressure differential when releasing the vacuum. As I already pointed out.
@@tedtrower9260 No, that's not how that works. Curing resin under pressure to squash air bubbles infinitesimally small does not lead to the resin, or whatever matrix is embedded in the resin, to explode.
@Switch & Lever: This agrees with my understanding as well. Cure under pressure in order to minimize bubbles and drive (thin) resin into the part. A quick vacuum before curing under pressure may help get rid of large bubbles adhering the surface of the part.
@MGoose1: VOCs shouldn't be much of an issue with epoxy resin. Polyester resin has high VOCs.

I've looked at some Russian research, and I've found a simpler method to make Opals. The trick is to grow quartz in an autoclave, and then heat-treat it to let it develop microcracks.
Here's a more detailed explanation:
The idea is let the quartz grow at 298°C at 30.5MPa in a solution of 1%NaOH and 10%Na2CO3, and it will grow with a speed of 0.4mm per 24 hours.
However during a prototype run with smaller quantities, they grew quartz at 326° 32.3MPa, 0.5%NaOH and 7%Na2CO3, with slightly faster growing rates.
The big chuck of quartz is then cut into small pieces. The pieces get covered in sand, and they get slowly heated up to 550°C. In the testrun they let it heat up 10° every hour, they kept it at 550° for 4 hours, and they let it cool at 10° per hour; with this process
you can possibly do that with a fairly normal pottery kiln
@@p.f.3014 Yeah!
Well, the 2nd part is fairly simple: just bury it in sand and slowly heat up while controlling the temp. We're talking about any sand, and atmospheric pressure.
But the process of growing quartz at 30Mpa is a bit trickier, that's 300 times our atmospheric pressure... You're probably better off getting commercially made synthetic quartz, which is not that expensive. But the quartz that you buy, should be made under the conditions that I mentioned.

I never understood chemistry in school, so I gave up on it despite having a love for it. But now I'm thinking I might actually be able to understand it with finding this channel! I haven't been happier in a while
So did you end up actually understanding anything or (like most people on these channels) did you just see entertaining videos by actual scientists and think "yes.. science"
Gotta love the stuff youtube puts in your feed some days
Now I want to make miniatures out of Opal through an injection mold
you could make some with resin and holographic powder...
Injection molding won't help, you can just use some molds and put in the opalescent water inside them (with a long vertical tube so that there would be enough particles for the whole nold)
Blue, grey and green eyes are also an example of structural color. Great vid.
That's cooI didn't know that

i have an Australian blue opal necklace from a small artist. it’s easily my favorite piece i own. it truly stands out
I'm so proud to have opal as one of my birthstones (the others are pink tourmaline, jade, and rose quartz)!🤩😍
Oh wow, I got hella confused when I saw NileRed's flasks. Nice to see collaboration. NileRed is one of my favorite chemistry channels.

Imagine your man gifting you a lab grown opal he made himself. Would be a keeper. Men take notes
it would be so cool if you offered workshops for this! It would be the perfect gift!
bro, this is blowing my mind. I've always wondered why roast beef can be sheen-y.
I thought I was crazy in seeing a rainbow in my meat. XD
I thought I was the only fucking one who actually cared😅
I'm already bored cuz this is all so over my head but if the answer to the roast beef mystery is solved, I'm gonna hang in there! Always wondered about that😎
Yes, roast beef northern lights!
I just want a bathroom tiled with black synthetic opal.
I wonder if opal is strong enough to coat a car with?
@@runed0s86 lol dude you just put metal flake in car paint to get light refractions, you dont need opal
@@bmxscape what if you coated chitosan car panels with opal? It would be so much better than car paint, and wouldn't rust!
@@runed0s86 don't eat the hype, man
There is a feldspar stone that is utterly black, fiery, and beautiful
This was the greatest crossover vid I have ever seen.
Hey mate would love an update on this, if you still have any samples that have dried out at this point.
Also have a suggestion that regarding the drying/resin impregnation. I've been making transparent wood using the peroxide method, bleaching with h2o2, curing under UV lamp to degrade the cromaphores, soaking in toluene to displace water/h2o2 and then vacuum impregnation of thermoset resin.
I'm not aware of how fragile the silica structure is in comparison to the balsa wood we used (~1mm thickness) but could you displace the water with toluene or other solvent, then put in a resin bath in a vacuum? even with a relatively thick resin it should impregnate the porus structure.
me getting stupidly excited over seeing nilered, my favorite chemistry nerd
Same😅
hsghdgsgshhs same lol
@@hanaaulia.x me too
The greatest crossover of all time
Relatable
Up until my fiance bought be an opal flower ring, I never gave much thought about their beauty. What is so beautiful about them is that something in nature is this beautiful and captivating and is naturally made by the Earth. It is so cool that it isn't one set color. And it matches absolutely everything you wear because it seems to reflect certain colors more when it is near any color. It really is a captivating stone.
Right?! Nature has so many beautiful Things and probably even Mode we don't even know of. So inspiring
Christa - opal was my favourite stone at one point. Now it is one among many favourites. Watermelon tourmaline, adventurine, mother of pearl, pearl, there are many fascinating optical effects in various minerals - chatoyancy, tiger eye effects, tha many stones that show various forms of asterism, the stones that are different colors in different light, stones that are a different color with reflected vs transmitted light, ctones like Labradorite, pleichroism, etc. - lots of fun, attractice stuff.
Opals are one of the most delicate stones, in ancient jewelry that had opals the stone hasusually dried out and crumbled. Pearl is also somewhat delicate but not nearly as delicate as opal. There is a mine out west that is open to the public that is loaded with large, beautiful opals, but they are useless as jewelry as the stones immediately deteriorate if not kept wet - they are mined just for the fun of it.
Check out bismuth crystals
Thing I like best about mine is even a few years later i still see new things,when I heard you always see something new I was sceptical but 100% the most beautiful natural stone/gemstone I highly recommend to anyone who is interested in minerals or stones you won't regret it even with the price tag lol
@@deandeann1541 I love how Alexandrite flashes purple or green depending on the lighting you're in. My mom told me when I got an opal ring that I needed to rub it on my face to oil it to keep it from drying out, and I did faithfully, until I found out that most opals (even natural ones) are sealed for use in jewelry these days...
But both chemically and physically speaking, pearls are WAY more sensitive, not only will the oils of your skin naturally change their color, but even MAKE UP can damage their luster (by scratching them) But don't take my word for it, just see how an opal vs a pearl react to red wine spilled on them and blotted off right away....
I love your channel! I would really like it if you made another opal video! I need more opal content!
Stabilizing resin could work. It doesn’t cure until you heat it. It’s very thin and can soak into wood to stabilize it. A brand I see often is cactus juice. Peter brown has used it before lol
I suppose in Canada Nile red is now a kind of a chemical Don Carlione.

@@fletcherspillers9904 yeah, sure
its Corleone
@Alexander Chohan Nile is easily one of the biggest chemistry channels I have no idea what you're talking about
That was awesome! Can't wait to see your take on the ruby production!
Thats easy. There are several methods. Chatham diffusion is best. The flame fusion, hydrothermal growth techniques using natural seed synthetic mtrls. LGF using natural conundrum, & is more of a filler technique. We'll see what he chooses.😁
@@roberttyrrell2250 flame fusion is by far the easiest for DIY
why not the rest.
Pretty sure the microwave is now the easiest :-)
can't you make cheap industrial ruby in a microwave with a crucible?
Some like Ethiopian opal are very interesting; they can exhibit much stronger attraction to water(hydrophane opal) and turn transparent! Some when cleaned and tumbled can even change base colors once clean! Some of my rough opal that was a dirty grayish white ended up a nice goldish orange when cleaned up. Australian opal have a unique green phosphorescence that’s also just AMAZING. The blue fluorescence results in a bright green phosphorescence that can last for several seconds up to a minute or two. It’s interesting to see the process of making a synthetic one, can’t wait to see what gem you make next💎 0:09 perfect examples of rough Ethiopian opal! They could look amazing polished but like you I saved several specimens to keep rough as one even has a plant root fossil! The way to check is to submerge them in water until they become completely transparent, which will reveal the other side of any host rock that the opal formed over. They’ll go back to the translucent/opaque state when allowed to dry in a dark area(not in direct sunlight though! That can cause cracks.) so it’s something to keep in mind as it was such an exciting discovery when I found the fossil in my largest specimen! And yes if it’s not already “crystal” clear I absolutely love opals😂
I have a 20+gm rough chunk and think it would help you analyze what they use to stabilize it. There’s a good amount of the material they used on the edges and in tiny cracks.
Nilered and you? Holy shit this is my dream.
wait there's a super new nile red one?
and applied science.
And even Peter Brown!
Jewelry companies:
**Nervous sweating.*
They're no sweating, they're gonna quadruple their profits now.
@@anunayy Nah, they'll just declare synthetic and moral gems as "fake" and continue on, like they did so far
It's clearly well within their power to convince most people that any synthetic production process devalues the product. Oh well, more pretty rocks for me.
You mean gem companies, right? Jewellery companies love cheaper ingredients for their arts and crafts.
Not likely. It's easy to make some low quality opals in your garage that are the strength of compressed dextrose. Producing high quality play of color and hardening them is another story. Good quality TEOS is also not cheap, and then there's the issue of doing this at scale. Hope you're a glassblower, too, because you're going to want to make your own modular boro settling columns to save money. Synthetic opals are pretty cheap, too. There's no way you'd be able to compete with the likes of Chatham and other labs.
This was the first video of yours I’ve stumbled across in my recommendeds, and I’m a huge fan of NileRed’s work. The algorithm actually works sometimes ??
Thank you so much. This is amazing. You explain things brilliantly, in an accessible way, my students will love this.
*** goes off to start building an autoclave and setting up chemical account!!!
