"A diamond is forever" is only true at room temperature. A zircon, however, *_is_* forever.

Hey Thoisoi, Thanks for pointing out the De beers story, it is a shame that not enough people talk about it and still spend enormous amounts of money on something that shouldn't be that expensive. Glad to see chemistry taking us to places that help the world in more ways than one!

I have a chemistry degree and found this video fascinating, very nicely done sir!

05:02 Don't believe I've ever seen a torch used to sharpen a pencil before...

I was surprised that carbon having the highest melting point wasn't discussed. What an amazing element!

I learnt so much from this video and will use many of the ideas for demonstrations for my students if I can! Thanks so much Thoisoi! 1. Pyrolytic Carbon: demonstrating thermal conductivity by cutting ice 2. Pyrolytic Carbon: demonstrating magnetic levitation 3. Burning a pencil but somehow the wood burns and carbon remains (I will try this with electricity, however, to demonstrate the electrical conductivity of graphite) 4. Using carbon dioxide gas from marble chips to extinguish a wood fire, and increase the rate of a magnesium fire 5. Obtaining an ampule of highly pressurised carbon dioxide to demonstrate supercritical gases and phase changes There must be others I forgot, I will rewatch this video and take notes. Thanks again!

When I was 16 I stole a small ribbon of magnesium from the school chemistry lab. At home I stupidly decided to hold it over the gas burner. Nothing happened for ages, and I almost gave up. And then the whitest flame I ever saw scared the life out of me. Luckily my mum's work tops were granite, because I dropped the flaming magnesium in a panic. I have more respect for it now.

@10:00 Exactly! this is why rockhounding is such a fun hobby. If you learn about gems and minerals you find there are way cooler/more useful minerals out there that are easily accessible

In Sri Lanka in local language Sinahala, we called Organic chemistry as Carbonic chemistry.

Ah, thank you for calling out the diamond scarcity hoax 👍🏻

Great video! Thanks for your beautiful experiments which help us understand the chemistry. Keep up the amazing work my Estonian friend !

When I was young I once kept a pencil in the centre of the gas stove and when the cas was turned on, after some time wood in the upper half of the pencil burnt out and I used the leftover graphite lead for mechanical pencil.

One of your best videos! Carbon chemistry is a huge subject but you covered a lot of it really well.

"Today happend to be a hot day" Toisoi2, November 2022 Man Climate Change realy entered the chat

Oh Maxim your videos are always so amazingly informative and entertaining, but this one is one of your best... among so many !

10:00 is when I stopped and clicked that like button. Well done! DeBeers is the very essence of the word "monopoly" .

So excited for another of your videos! Glad to see you're nearing 1 million subs, that's huge! Good work dude.

Ah yes, the only element on which a significant portion of Chemistry is based.

Diamonds aren't rare the supply is kept down to increase the price. Also same with oil. Keeping the supply down increases the market price.

I freakin' love science! Thank you for your contributions to this wonderful endeavor!

this is the coolest damn channel in existence. Seriously.

One of your most interesting videos, Tholsoi. Sometimes the most common is the most fascinating when looked at unusual angles.

- Thoisoi: Teaching me everything about carbon. - Me: OK, so magnesium is so badass that it burns in CO2 atmosphere and under water. It burns no matter what, it just doesn't give a s.

You always deliver top quality videos! Thank you.

OK, that pyrolitic carbon stuff is something I never heard of and it completely blew my mind.

Your videos are great man. Thanks for making them.

Superb video packed with great information! Thank you for the gift of knowledge!

Outstanding video, mate. Loved the transition part. Mesmerizing, indeed.

You do make great videos, ,always cover the subjects completly

Pencils have a h1/h2/h3 number when mixed with china clay (aluminium silicate)

The testing device is checking thermal conductivity, moissanite is also thermal conductive, that’s why it tests as a diamond. But diamond doesn’t not conduct electricity, moissanite does.

I love this channel! Amazing video!

Thanks for your very informative video! Keep up the effort

I always enjoy and learn a lot from your videos.

What is that electric art piece you have on your wall? It's awesome!

I can't get enough of this guys content.

Awesome video man , keep up the good work 👍

Glad you're uploading again. Also, Raid Shadow Legends really gets around.

keep the Info coming! thanks Professor

I learn so much from your videos. You're awesome.

man i love watching these usually but now im just hungry too i LOVE your vidoes please keep making them there always so interesting !

Silicon-based Thoisoi2: "Carbon-based lifeforms are practically impossible in our world. Maybe this could be possible on some other planet with highly strange conditions..."

wonderful presentation today, thank you.

neat to see the copper dye used in making the pencil green at 4:50, you should talk about flame tests as it's own video, I'd love to see you cover it

We really missed your voice sir glad you uploaded a new video exciting to learn more about Chemistry although I'm not that good back in my okd days but seeing and hearing it from you feels like it's very easy , informative and very enjoyable. Keep it up always sir. With great respect all the way from the Philippines 🇵🇭😁👍👍👍

I really love this channel. The videos always spark my imagination. Even the paid ads are done very well. 👍

Without Carbon, we are nothing. God bless carbon!

Great video with your original great voice. Well done, thank you!

Well done! Very good and informative video!

thank you I loved this whole video

Moissanite is not fake (but of course is not a diamond, too) as long we speak about the mineral, and not its synthetic analogue, the so-called carborundum.

You tube is a blessing from the creator as we can learn from best of people from around the world like you, you are my favourite KZfaqr regarding science and knowledge though you never gave a heart on my comments.

At 20:10 it is stated that cyanobacteria started using "carbon dioxide and water as a source of energy". That is not correct. They were using other sources of energy, mostly sunlight, to convert carbon dioxide and water to complex organic compounds (such as sugars and other carbohydrates). It takes energy to react CO2 and water to form other compounds and oxygen, which can then be consumed by animals that eat the cyanobacteria or plants to produce back some of the original energy ("burned").. Bacteria/plants can also consume some of their carbon compounds to produce energy when needed. The important part is that cyanobacteria and plants capture sunlight to produce complex organic compounds from simple inorganic inputs like CO2, water, and some minerals (Mg, Na, Ca, Fe, ...) in the process storing some of the energy in chemical form.

I always learn something every time I watch your videos. I love your videos and channel. You explain a lot. Be safe in your part of the world. I love your cat. Very sweet.

This by far is one of the most interesting review on carbon!

Awesome video. I love the science of chemistry and learning about chemical reactions. It’s insane how one chemical can react with other chemicals. I should’ve been a scientist

This is one of the best videos I've ever watched in my life. Well done! 👍👏👏👏👨‍🏫🧑‍🏫

I just LOVE your videos!!!! You ALWAYS teach me something I didn't know, and that is THE GREATEST THING POSSIBLE!!! If you aren't learning new things everyday, then what are you doing with your life?? You're certainly not PROGRESSING..... I just can't wait to see what you make next for us!!! (could you PLEASE continue to make longer videos like this one? a 20 minute video is just enough that I can lean back, maybe with a snack, and enjoy the video during a relaxing amount of time..) - I can even enjoy my lunch while watching just your video, instead or two shorter video that require 5 or even 10 minutes of searching for another good one after the first short video is over.... what a waste of time! - PLEASE, if you can, make your videos AT LEAST 15 MINUTES LONG!!!! 20 MINUTES IS BETTER, BUT 25 MINUTES IS THE BEST!!!! - But this is only my opinion.... the rest of your audience may prefer the shorter, sub-10 minute vids.... ... BAH! You just continue making your videos however long YOU want... I will watch them ALL no matter WHAT YOU DO!!! You make chemistry SO MUCH MORE INTERESTING!!! (Plus I sometimes get a glimpse of what life is like in your part of the world and I can see the differences in having Russia as the main influence in culture as apposed to America..... it's nice to see the world from different eyes :D ) THANK YOU SO MUCH FOR EVERYTHING THAT YOU DO!!!

The disappearing diamonds was out if sight ! New Subscriber

Looks like some nice weather in Estonia this time of year!

Always interesting and informative thanks for taking your time to share your knowledge !!!

Always awesome experiments!

18:43 ..... WOW! That's incredible!

"That's why I urge all my viewers not to be tricked by these monopolies" And you didn't get demonetized for that? Bravo

The thumbnail looks like a 140-year old bald man winking at you at his last breath

13:58 He should've given more attention to the graphite block with the UV, that looks really cool as well

Normal pencil lead is only about 40% graphite. The rest is actually a ceramic. Both are mixed together in powdered form, and compressed into rods, which are then glued in a wood sheath to make a pencil.

What the difference between carbon and my ex? She could form more than 4 bonds at the same time.

What an another awesome video! Carbides need to be covered in depth.

Wow, that’s cool. I’ve always wanted a magnetic hovering object that didn’t need a power source but I didn’t know how to make one.

Hi Thoisoi, I wanted to find out if you are speeking the English voiceover with the pleasant Russian accent on your own. And after enjoying some original episodes, I was surprised that both the Russian and the English versions sounded similar. That's a great job you do for us with every episode. Thank You!

Make sense why fireworks burn brighter due to the magnesium sparks also reacting with the carbon from the other materials burning in the air, making bubbles or pockets of carbon dioxide in the explosion.

a great &informative video as always. Thank you very much! Could you please reference the music you're using? Thanks once again 😊

Stunning!

03:28 I can’t help but think of That Chapter when this music plays 😂 I doubt most of you have any idea what I’m talking about but if you know you know

It's kinda funny how he wears a cyberpunk shirt while talking about carbon

That was a very good video thankyou

I think I speak for EVERYONE when I say. We want THIS voice back Bring back the OG voice

Carbon is a bit rough around the edges but polishes up nicely

Hey! One of my favorite channels.

Chernobyl was a good example of graphite burning

10:48 Didn't expect those exotic engrams (Destiny reference)

The best chanel in youtube to learn chemistry.

Your best video so far!

Nice video! Are amorphous carbon and glass-like carbon mentioned?

I love when people post comments after 2 minutes of a 25 minute video

Love the rant about De Beers. I wish more people understood this.

Best channel on KZfaq by far😎❤️👍

Coal and diamond, made from the same element, two different allotropes, two different values. 😂😂😂

What is most strange is that no lifeform is possible without Carbon

I want to buy that floating disk cubes!

A chemistry channel PR for a video game wtf xDD

What is that awesome electrical tube lamp thing hanging on the wall in the background?!?!?! I need one!!

the steel in his grill: *has carbon in it

2:57 "All of diss iz a reshult of a proparticle alectrolofish ich allaws wan chemical element tu take different forms"

Hey Aye tums! Thanks for the awesome results!

Thumbs up and subscribed!

Lets talk more about who made diamonds so expensive

This video is so freaking cool
