Growing Copper sulfate giant crystal at home! Grow crystals chemical experiment (4K) 

yes, t-shirt is ideal for this :D thank you for watching!

thank you so much!

😂😂

Since copper sulfate is easily absorbed through the skin, you must be extremely cautious to avoid even minimal skin contact with it. If contact occurs, it can cause itching and permanent yellow discoloration of the skin.

Great, I'm looking forward to it.

Only takes 1g inside your body to cause toxic effects and 10g to kill you... Since copper sulfate is easily absorbed through the skin, you must be extremely cautious to avoid even minimal skin contact with it. If contact occurs, it can cause itching and permanent yellow discoloration of the skin.

The best way is to buy it in store

Actually I wouldn't be afraid of working with this one without mask, if you protect your eyes, you are fine :) I am not sure though if it's suitable as a pigment as it dissolves in water quickly. Have you heard of azurite?

@@danvoznak yeah ive been looking into alot of these minerals :D and thanks for the tip. maybe it could be for watercolor. ahahah

@@adenstirn great good luck! Feel free to share your results then😀

@@adenstirn (also the copper sulfate oxidates and turns white pretty quickly once dry)

Exactly! 😁 Thank you for you comment! And sorry for my late reply, the comment ended in revision section I didnt see it earlier

Thank you :)

I am glad the video is helpful. Wish you a successful experiment! 😀

That is definitely way how to grow the crystal almost forever, but no. It is risky. I did it once, but the original crystal dissolved, although the new solution was saturated for sure. I had no idea why it happened.

I’ve tried that. It doesn’t work. Just keep the main Crystal in there and filter every so often until you have no extra crystals growing on the bottom of the vessel.

In my opinion, your solution is maybe not saturated so the crystals are dissolved

The biggest problem is that what's left behind is impurities and copper sulpgate. The impurities can be removed through a recrystalization procedure. Save and set aside all the small crystals untill your done growing your big crystal from your first copper sulfate bath. The remaining bath you grew your big crystal in will have impurities that have collected and concentrated. 1) Pull your big crystal out. 2) Then recover the remaining copper sulphate by boiling the solution unill it it's so super saturated it starts to form crystals while it boils. 3) Remove heat and let cool. Once cooled let it cool further in a fridge. Over night. 4 The next day should remove the crystals the new small crystals . What you'll have is relativly pure crystals and concentrated contamination remaining in solution. 4) you might try to recover additional copper sufphate and reprocess the contaminated solution but you'll likely get less and less copper sulphate with increasing levels of contamination. 5) Now take all your small crystals from the big crystal grown and the copper suplhate recovery, and do a second recrystalization. The crystals you collect from your second recrystalization will be a very high purity, and the remaining contaminated solution can be further processed later to recover remaining copper sulphate. 6) After your second recrystalization you will have very high purity but small crystals. You may now redisolve them in distilled warm water untill virtually all the crystals are disolved. Then let cool to ambient temp. 7) Filter off crystals that formed while cooling. 8) Your new batch of copper suplate solution is now purified and saturated at room temp and ready to reinsert the big crystal and resume its growth.

díky :)

Go for it! :)

Wow, congrats! What's the size? Feel free to share the result!

Is 9 centimeters and weighs 210 grams, result on this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-U7_PLzs84QU.htmlsi=HD5lr5p_WXphmKuU

Is 9 centimeters and weighs 210 grams, result on my chanel

Great job! There's a lot of ways of growing crystals :)

@@danvoznak I think mine is about 200g and about 13cm long

@@audiotron1003 awesome! What's the shape like? Similar to mine or different?

Not really - the main rule is to avoid swallowing the sulfate and to protect your eyes. If it comes into contact with your skin, wash the area right away.

Thank you!! This experiment is relatively easy and rewarding! Let me know how it works out.

Thank you!!

Thank you so much, it means a lot. Luckily, people in Reddit really like this video :) Have you tried to share yours on this social network?

@@danvoznak Yes I did, but I only seem to get abuse from the people on there, so I'm getting really disheartened by the whole thing at the moment. May have a break from making any new videos as my private life is getting very busy and I just don't have as much time for it. Maybe in the future I'll start up again. I wish you all the best and please stay safe.

@@pixietwo oh :( I am sorry to hear that, sometimes it happens to me too. I hope you are spending time on something you enjoy or find important. Stay safe too and I'm looking forward when you will be ready to come back with new videos!

Ahoj! Nejsnadnější na kristatalizaci i sehnání je modrá skalice, ta je určitě v obchodech jako OBI, ale i v květinářstvích a domácích potřebách. Ostatní je nutno sehnat z netu/specializovaných obchodů zaměřených na chemikálie/laboratorní vybavení.

273 gramů. Z Česka

@@danvoznak Môžem otázku? Práve vytváram kryštáľ modrej skalice a s čím mám problém, tak sa vytvárajú malé kryštáliky okolo lanka, ktorým som omotal kryštáľ. A použil som rybársky vlasec.

@@samuelbudzinak jo, to se stávalo i mě. Děje se to hlavně ze začátku pokusu, pak už moc ne. Vždycky krystalky mechanicky odstraňuju, nejlépe dříve, než se spojí s hlavním krystalem.

Great! Wish you a successful experiment and look forward to hear about the result!

hey! it's been four months since your comment... did ya grow one??

@@Hexzit Hello! Yes, I've grown a few, they actually grow really fast if you heat up the solution a bit every 1 or 2 days. It works really well, takes some trial and error, but it's a pretty good project for beginners overall. Currently growing like my 7th one haha! Have you grown any?

Thanks for the question, I do not recommend jewerly out of Cooper sulfate - it is easily damaged by water or just humidity.

@@danvoznak ah, I see. What if a put a good clear coat on it? Would it still be too risky? Thank you for your answer :)

Thanks!! 😄

@@danvoznak

Chemical formula is the same, but chalcanthite is used for naturally grown copper sulphate crystals. This mineral should be treated carefully, however copper sulphate is commonly available chemical used for cleaning swimming pool water etc. The most important is to protect your eyes.

I am glad you liked the video! Yes, it takes some time and they might slip out. It's better to do 2-3 knots

@@danvoznak Thank you for the reply. Im wondering if you ever tried and I may experiment when I get the supplies; to put small plastic/silicon molds on the bottom of the container to see if they fill up as solid crystals. Then just pop them out when they are done. I will let you know if it works Dan, thanks again.

@@ChristopherSchiffermiller sounds interesting. I think they'll fill. I look forward to hear the results :)

@@ChristopherSchiffermiller however the upper layer will be growing naturaly

@@danvoznak Hey Dan, I just finished my experiments and made a video, see below. I didnt get the molds just yet, but I did three different grows in one bowl. Let me know what you think or if you have any advice or ideas. Im going to see if I can grow it on sea shells next, as growing it on the rock came out awesome. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KQ4cE1xevN0.html

thank you!

chemical formula of copper sulfate

Thank you!!!

Thank you:)

thank you! Congrants to you too :))

Thank you!

Thanks!

Thank you!

Thank you!

The acid is eventually used up.

My home inverter battery terminals are already full of bluish white CuSO4

Thanks a lot for recommendation

@danvoznak your most welcome 🙏 I realy love your crystal growing episodes. I suggest you to grow wulfenite ( PbMoO4) it's easy to grow but wonderful. you just need lead nitrate and sodium molybdateand distilled water it's really simple and cheap to make but the result is shocking good.

No I did not pierce and I do not recommend it. It takes some time and mainly patience. I did the knot firstly, then I tried to fit the crystal there and then I tighten the knot. Later the nylon grows in the crystal... just the first day is problematic 😀

@@Jawst I agree being careful is important however I can assure you there is not any permanent color change of the skin. Let's not forget the usage of the sulfate in swimming pools etc

​@@Jawst I've been growing copper sulphate crystals for years, and handled directly my sin did not turn yellow nor have I circum to any ill effect.

The key ingredient is copper sulfate. Then some cloth to filter, some small container, nylon, hot water. Everything is explained in the video! :)

Yes it will

Nejspíš nemáte dostatečně nasysený roztok. Zkuste příště raději menší množství vody a více chemikálie.

Voznak pise, ze to mas kazdy tyden vycistit, v tom je ten problem. Kdyz to tam nechas moc dlouho, tak ti sul krystalizuje na nadobe na care hladiny a po teto vykrystalizovane soli ti roztok vzlina nahoru a krystalizuje tam dalsi a dalsi sul. Sul krystalizuje i na dne nadoby. Proto se koncentrace roztoku snizuje a krystal se muze dokonce i zmensovat, misto aby rostl. Takze pravidelne cistit a pokud je potreba, doplnovat sul do roztoku. S kamencem je to komplikovanejsi, protoze to trva dele.

Jedná se pak o pokus "vytěsňování mědi" - po vložení železného předmětu se okamžitě na železe začne tvořit měď, která zašpíní roztok, který se znehodnotí (začne se zbarvovat do zelena kvůli vznikajícímu síranu železnatému).
