Hi, today I will tell you how to grow a green crystal of Mohr's salt. Mohr's salt is a double salt of iron ammonium sulfate. To prepare Mohr's salt we will need iron sulfate and ammonium sulfate. These substances can be bought in a chemical store or via the Internet. Take a large glass and weight 60 grams of ammonium sulfate and 138 grams of iron 2 sulfate in it. Next, add 400 ml of very hot water to the mixture.
Mix the solution until all the salt is dissolved. The solution will begin to acquire a brown color due to hydrolysis of iron 2 sulfate. Now leave the hot solution for a day to cool down and to precipitate out the seed crystals on the bottom. A day later we can see that a lot of small green crystals of Mohr's salt have grown at the bottom of the glass. Also we don't need the iron oxide precipitate that is as well on the bottom of that glass. Take the filter and filter the solution into another container.
However, no need to filter the small amount of solution that contains unnecessary iron oxides. It is better to pour out this residue. Now you need to select a seed from the mixture of green crystals that have grown over the night at the bottom of the glass. The seed is a small crystal of which a large crystal will be able to grow in the future. Crystal seed must be of a regular shape and largely enough. You must bind the seed of your choice to a thin line and hang it in the filtered solution of Mohr's salt.
Now we shall put the glass of growing crystal in the closet, to protect it from dust.
Over time the water will evaporate from the solution, and the excess salt will form a large single crystal of the seed. After about 2 months, my crystal has grown enough and I decided that it is okay to stop its growth. I also had a crystal growing in a smaller cup. Now I’m pulling the crystal from the solution and, as many of you already know, covering the crystal with the colorless nail polish.
If you decide not to do it, the crystal may eventually turn yellow and lose its original appearance. Also, the iron salts have a rather strong smell, and I do not want to get the smell of iron on my hands after I grab the crystal. When the varnish is dried you can evaluate the work that was done and examine the crystal more closely. The ideal crystal shape should be symmetrical and have a complex prism. Crystal shape is defined by the crystal lattice of a substance. As can be seen, the shape of the my crystal is prismatic, but with some defect. We can see that some faces have irregularities and flaws. Also, the crystal is not fully transparent, all this testifies to the defects in the crystal. Ideally, the crystal must be transparent.
The defects in the crystal are due to the temperature fluctuations during growth, the presence of dust in the solution and the resulting iron oxide contamination.
However, the crystal of Mohr's salt is still quite beautiful and can be a nice decoration in the house. Although in practice, this crystal can hardly be applied anywhere.
Crystal is quite fragile, if you drop it on the floor, it will break apart.

Keep doing this videos with crystals man are awsome
i like ur accent for some reason
**names dat boi**
**crying lenny face profile pic**
u want something=
When I saw this video 2 years ago, I wasn’t thinking seriously to make this experiment. But finally I had the opportunity to grow my own crystal from Mohr’s salt! If I could I would show you, but it is not as regular as yours because we were few students to take turn on this project and we could filter the solution just once a week, which is not enough. But the result is beautiful so thank you for inspiring me!
I note that this video lacked the customary period of enjoyment of their beautifulness without any further comments. Was this due to the defects in the result?
+Godfrey Poon When it was grown... like all crystal, it was inspected.
If it'd been small or wiggly or cracked or misshapen...
... it would have been discarded.
+Luis Daniel GP hello
Debbie Baker And goodbye to anyone standing in John Cena's way!
You are so right...
*now i can defeat Super man*
this comment made my day xD
E M M A muahahahahahaha great idea
LMAO : )
E M M A oh god that just mean😢😢😢
@@katewalpole3811 yeah, that's just downright rude, dude.
is it possible to evolve my pikachu with this crystal?
screw that make a lightsaber from the crystal
+Airimas16 yassssssssss i did i made a new one
You can, but you'll need more Mohr's.
@@Airimas16 no make the time stone and go to dark dimension and kill dormammu
@@babujohn2692. There are a lot of useful green crystals huh...
Great Video! Looks a lot like an Emerald
did you just make kryptonite with earth elements
Thanks for your videos, I ve tried all of your crystalgrowing videos and its awesome!! please make a video explaining the growth !! greetings ffrom mexico !!
Please keep doing crystal videos, lots of people, including me, love them
Where are you from?
You sound good for someone who doesn't speak English as their native language. Don't let anyone belittle you Thoisoi. I've seen some of your other videos where you used a computerized Microsoft Sam voice, and THAT sounded HORRIBLE.
+thebestofall007
I'm pretty sure he is Italian as to those idiots that do mock him it just shows their small intellect as he can speak more than one language and is having a good decent go in a truly international community any decent human being would appreciate this diversity after all if you think it about it the renaissance could have well been the catalyst needed to get where we are today speaking to others from around the globe via this wonderful thing called the internet on a an amazing machine called a computer...;)
+rabbitphobia From what I have seen with the language in any graphs and literature used in his videos, he is Russian.
***** He may well be not that it matters but I am pretty sure I have heard him speak in Italian anyway it doesn't really matter the fact is he makes science fun which is more important than his nationality.
+rabbitphobia true that.
+rabbitphobia i think he's russian as in his main channel the text appears to be russian
Well this is the third video I watched and that was enough to subscribe.
I found these on the floor, idk if it’s a crystal or plastic but it’s cool
I enjoy all kinds of crystal made in your channel. Astonishing! :)
The crystal vids are amazing!
Thank you
Excellent - thank you 👍
a couple years ago I recrystallized and recrystallize and recrystallize Rochelle salts it's alright finally had one single Crystal so pure and so clean it look like glass it was about 3 inches long and an inch and a half tall piezoelectric Crystal someone knocked it off the Shelf out of the beaker of busted and dried out and fell apart before I noticed it was gone
evaporation method is slower, but usually gives clearer crystals. cooling method forces rapid crystalization which usually makes crystals cloudy and opaque. evaporation method can produce almost glass like clarity.
Would love to see more crystal-growing videos!
CUTE! The cat again but I love your acsent and the crystals so so so just amazing
I have just found you channel, and I am really enjoying it. Do you think it will be possible to do a time lapse video of a crystals growth.. Something like a time lapse video of a plant growing?
What about the: "let´s enjoy the beautifulness of this crystal without any further comments". Come on!!!!, that´s your line!!!!!
you may also choose to go to an art store and invest in a sable hair brush, or synthetic mongoose hair brush. they will allow you to cover the crystal with nail polish without leaving streaks.
Really like all your videos. Keep them coming.
This one looks precisely like Kryptonite; Wonderful!
dude I'm shocked that you don't have a lot of subscribers, ur channel is awesome
George S. He has more than 300,000 subs
When you watch all the crystal videos and want to make them all, put them in your backpack, and "be an adventurer" end quote.
I MADE IT AND NOW IM INVINCIBLE
Try making copper acetate crystals, those are really neat if you grow and keep them properly
+Sergeant Methcake Or maybe nickel sulfate crystal or a a large magnesium sulfate crystal or something
Nice video ^^ love all the crystals you've made! Btw song a the end?
Question: can I attach this to my earings?
I mean it's salt and it'll probably dissolve-
yes I guess, just make sure to put at least 3 layers of nail polish on it
I wonder if resin would be better than clear nail polish to cover it...
Excellent video, looking forward to the next one.
It would be interesting if you could cut the large crystals that you have grown cut into fine slices which have plates attached to each side to be used to keep oscillators on frequency.
You should add some concentrated Sulphuric Acid before adding water to prevent the hydrolysis of the Iron Sulphate. That will prevent the oxides from forming.
Isn't sulphuric acid dehydrating agent so it might remove the water of crystallization
The sulfuric acid added MUST be dilute. If concentrated sulfuric acid is added it will oxidize all the ferrous ions to ferric and you end up making something analogous to alum instead
Im definitely using this for my drug urine test. From urine colour to dangerous green. Now i can tell the narcs i did not snort drugs, i EAT uranium!
Question: Can these crystals be polished gently?
John A they are very very soft and I believe they devolve in water, it may be hard to polish wet
Next video teach us how to grow nickel sulfate crystals. I have been trying but I dont know what temperature to have it because temperature affects the crystal growth. :D
Thanks for sharing these videos! I'm gonna try to grow some crystals too
Very cool! 👍
You can take a sharp tool and shape it
Looks like a tiberium crystal ))
This is awesome!
I had the same thing for practical today at school but since time was limited we approached a different procedure
After adding the hot water to the salts mixture we let it heat for some time and were supposed to observe some minute crystals in the process
Mine turned into a thick moss like paste and the teacher didn't accept it
Did I overheat it?
I just don't know at what point should I stop the heating bcuz i believe correct me if am wrong
Crystals don't form just on heating right they need to be cooled down after that as well right?should I have just heated the solution till it was completely soluble and not have waited for any crystals while heating it?
Can anybody help me with this?
It's not like I can find these chemicals in a local store... but can I make them? :O
Can you cut it and polish it to look like emerald?
I doubt it. It seems extremely fragile.
i guess it wouldn't still be particularly transparent because of all the particles trapped inside
mauro foti
You can say the same for most emeralds... Most are opaque, some are translucent, but only very few are completely clear and transparent. Even in the world's most prized emeralds, you will find some inclusions.
I love grow in Crystal s
awesome vid
and btw love ur accent
superman beware..kryptonite :D
Why does my crystal appears to be milky white rather than the expected green? Idk if it is because I added slightly excess ammonium sulfate.
Its like school except cool!
This is awesome
Oh Edmond, can it be true, that I hold here in my mortal hand, a nugget of purest Green?
heyy, very good channel, amazing your skills, dude, i will make my own crystals, super cool music, i suscribe now, greetings ;)
Would you recommend to add a bit of sulfuric acid to the solution to prevent oxidation?
Make a vid where you grow a huge crystal like 2 pounts
Off to make tiberium !
how thick is the layer of nail polish? I tried a single coating on a crystal of MgSO4 and after a month parts have started to go from clear to white.
This is cool !
Can these crystals be cut without cracking to crumbling? If so what would you recommend to cut it with?
can a crystal be safely made at home using ferrous sulfate only?
Kinda reminds me of the evolving crystals from pokemon red and blue :)
Sir, I need your help. I am making nickel sulphate while I am not maintaining its pH. When nickel and sulfuric acid are reacting, the head turns into crystals. After the crystal dissolves in water, the PH reaches 1.3 when the PH should be 6.0. Can you tell me how to change PH from 1.3 to PH 6.0?
MAN,just keep making more videos
But can't you use normal salt and food colorant to make colored cristals ?
Your cat is so pretty omg
are these crystals strong ? can they be used in jewelry ?
If you find a seed of good size but bad shape can you sand it down to a shape you like?
can I do it with just the iron sulfate
So I'm starting to wonder what happens if I take the green one and hang it in the purple solution for a little while then back to green then going back and forth until it is the size I want, just to see what happens.
amazing, you are smart
Can you chip at the crystal be shaped without it breaking completely?
Can u only put one seed in or can u put two?
What happens if you just use iron oxide. I tried that and its still cooling
Can I leave in uncovered untill it turn yellow?
I can't find anywhere a way to grow yellow crystals, and I wanted to create a set of Infinity Stones.
Followed your step, made light blue crystals instead..
I really like your cat 😆😻😻
can you make it from regular salt or you need all of those chemical things...
Regular salt would come out as a cube since NaCl (Halite) is part of the cubic crystal system. But growing a large Crystal with regular salt is possible.
Can I grow blue, octahedron crystal ? I really need help to find the right salt cuz every salt that's blue is just like a rectanglular shape and I want it diamond shape :((((
PERIDOT!
Can I from green crystals directly from Mohr's salt?
Is there any other way of sealing the crystal other than a nail polish?? Would epoxy resin do??
Nicole Capobs Everything that is clear, and keeps it away from air and moisture works.
Can this be done with copper chloride?
can I just use normal saltand add green food coloring?
SenpaiKiseki No because the salt itself isn't stained but the water around it, the crystal will be very very light green because it traps some water in it but it wouldn't be all that nice. Use Nickle(II)-sulfate •6H2O instead. Looks equal.
how long does this process take.
Instead of using clear nail polish, could I use Mod Podge?
If i polish the "seed" in the shape I want will the finished crystal have the same form as it's polished seed?
The shape of a crystal comes from the arrangement of the atoms, so I don't think so.
can I replace the ammonium sulfate with alum?
Where did your buy this stuff
is it possible to grow the crystal in a form so i dont have to cut and polish it ?
karel hastik The shape is defined by the molecular structure. If you want different shaped crystals you should settle on one and search for crystals that form such shapes. Hope it helped
What filter do you use?
Great video.
How do you make blue crystals, like the ones they made in "Breaking Bad"?
Anyone know where I can buy these chemicals?
do how to grow yellow single crystal of sulfur
can u use normal salt?
How many degrees the final solution ?
does these crystal are fragile like class or solid like a rock
It's a little more sturdy than glass, it won't shatter but if you drop it, it will break into smaller chunks, definitely not as though as stone by far
congratz
