In this video I show that diamonds aren't forever by burning some! This experiment is actually how it was discovered that diamond is made of pure carbon.
But you're probably here for the links:
Diamonds: bought on eBay from seller "hattongardendiamondsonsale". It was a few years back so no link, but what I bought was titled "5carat White good quality 1.00mm Loose Rough Diamonds 100% NATURAL uncut russian" and cost me $30.
Oxygen bottle regulator: www.amazon.com/gp/product/B00...
Technical Glass Products: www.technicalglass.com/
They make all sorts of quartzware, including test tubes and flasks! Definitely recommend them for your quartz needs. (They didn't pay me for the advert; I just had a good experience with them.)

Ok i really think that apart from one comment noone mentioned how good this video actually was. It isn't easy to find videos with that much work in it which are also very enjoyable. Thanks a lot, this just actually made my day because i love when people share my passions and are passionate enough to produce high quality videos! :)

@mrhomescientist 6 лет назад

Thank you very much! That's very kind of you. I like to include more than just the reaction, like setup and breakdown, so people get the full experience of how science is really done. Tends to make my videos very long, though.

@kjpmi 6 лет назад

Hey man. Another great video. I really do enjoy all of your videos. I like how you document any issues you run into and the whole trial and error process which everyone else seems to cut out of their final videos. I think it's a lot more useful to keep all of that in there for people who are actually going to use the video as a reference in stead of just pure entertainment.

@mrhomescientist 5 лет назад

Hey I know this is a year old, but thank you very much for the comment. I'm glad people find my stuff entertaining and useful. I definitely run into a lot of problems. I've failed an experiment twice now for my next video, so it's taking extra long to get done!

Loved the video Very good content Thank you so for helping me understand this reaction

@robmckennie4203 6 лет назад

It's weird that the oxygen regular is left hand thread, generally oxygen is all right hand and fuel gas is left hand. The purpose of this, as I believe you say in the video, is to to help distinguish oxygen from fuel gas. I suspect that possibly this particular form factor is mostly used for fuel gas, and therefore fuel gas gets to be right hand thread.

@khaliffoster3777 3 года назад

So, you use the oxygen to force the gas off the diamond to lime water, so it mixed to show a reaction that is opaque. There is another way to show lime water to become opaque in other gases? Ya can try with different gases to change from transparent to opaque. So, regular water will not change to opaque.

@nicktohzyu 6 лет назад

13:00 the thermal conductivity does not matter as most of the heat is lost by radiation. Thermal conductivity would only matter at a far larger scale, due to the square-cube relationship.

@timwong3605 6 лет назад

Yes, the true reason is due to diamond's low specific heat capacity

@HighFidelityFox 6 лет назад

How much was the vial? Could you link on ebay? Also I remember watching something like this on Pawn Stars lol

@robmckennie4203 6 лет назад

Search ebay for diamond powder. Prices vary depending on various things, such as gem quality or if the diamonds are sized for use as an abrasive. You could spend as little as $10 without shipping, but you'll have to take a look and find one you like the look of.

@HighFidelityFox 6 лет назад

Rob Mckennie cool, thanks man

@mrhomescientist 6 лет назад

I'll put some info in the description. It was a total of 5ct white natural diamonds, ~1mm size, for $30. Seller was "hattongardendiamondsonsale". They are really beautiful, but small! Some of them even have the natural tetrahedral shape of diamond crystals.

@joysstreasuremap100 2 года назад

There must be a way to forge diamonds. There planets that. Rains melted diamonds. High pressure and extreme heat. Not sure about the chemical makeup of the atmosphereon those planets.

@garycard1456 6 лет назад

Next video: the allotropic conversion of C (graphite or coal) to C (diamond). by use of high pressure and heat. I have heard that if you stomped your feet on a piece of coal daily for 1 year, diamond will form.

@kitsumyr9752 6 лет назад

Gary Card i have to disagree with that,iirc diamonds only form when both high pressure and temperature are present. Stomping on a coal everyday wouldnt give it enough heat and pressure to turn it to diamonds.

@tmfan3888 6 лет назад

if u used large excess of limewater then CaCO3 will definitely not redissolve

@mrhomescientist 6 лет назад

Good call. I used a small amount because the more I put in the wash bottle, the higher pressure is required to start bubbling through it. I didn't want to blow the diamonds around in there!

@dusanpavlovic2201 6 лет назад

why didn't your tube melt if diamong at 3550 C was sitting right there

@mrhomescientist 6 лет назад

Where did you get 3550 C from? Diamond ignition temperature in pure oxygen is only around 900 C. They gradually gets hotter as they burn, but the tiny size of the diamonds mean they burn away before much heat can be developed. Plus quartz glass doesn't start softening until around 1600 C, and it transfers heat slowly, so there's plenty of time before the glass starts getting damaged.

@dusanpavlovic2201 6 лет назад

mrhomescientist can you explain how is this possible if i found articles that say that diamond burns at 4000+ degrees ender pressure some say it burns at 3550 deg and yet this is possible, can you do that with iron or tungsten?

@mrhomescientist 6 лет назад

If it said they burn at 4000 degrees under pressure, then there's your explanation. My system was not under pressure. It just had a constant slow flow of oxygen gas passing over. If you send a link to one of those articles I can take a look. Iron burns pretty easily; you can light steel wool on fire in normal air with a 9V battery. Tungsten is probably a lot more difficult.

@dusanpavlovic2201 6 лет назад

mrhomescientist can you burn steel like that and how does diamond compare to other elements could they also be burned like that i read that diamond melts at 3500 but this is burning what is the difference and how can diamond burn under so little heat you sait 900 deg

@mrhomescientist 6 лет назад

Steel wool is steel, so yes. You'd have to look up combustion temperatures of other elements to see how they compare; fluorine is probably the highest I would guess. Melting is turning from solid to liquid, a physical change. Burning is a chemical change where the element combines with others to form new things, in this case going from C to CO2. They're very different processes, hence the different temperatures.

@bjoe74fm Год назад

lol, I did the burning of the diamonds 30 years ago, I recieved instant validation diamonds are not for ever lol, did it even before eBay and the internet

@TheAxecutioner 6 лет назад

Great video !! What temperature (F) do you think was reached while burning the diamonds?

@mrhomescientist 6 лет назад

According to gemsociety.org, "The temperature of diamond ignition in pure oxygen is 690º C to 840º C." That's 1274 - 1544F! Not all that hot, really. Pure oxygen really enables this reaction, and I'm not sure if it would work in open air.

@TheAxecutioner 6 лет назад

I am surprised, I was expecting much higher!

@TheAxecutioner 6 лет назад

That does make sense though because Thunderf00t tried to melt gold with a burning diamond and was not able to do so. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xlJxNoU7xqQ.html

@mrhomescientist 6 лет назад

Bradyn Austin Cool video. I suspect it didn't melt because the gold conducted the heat away too quickly, plus the stream of oxygen is cooling it. Very different experimental conditions than the graphite melting gold he showed earlier!

@TheAxecutioner 6 лет назад

Indeed. If the gold melts at 1948 & diamond burns at 1544, the gold will offer a small chuckle in response. What happens to diamond when heated with something like oxyacetylene? Does diamond just vaporize quickly? Or something cooler?

Curious: How much were the diamonds worth?

@icebluscorpion 6 лет назад

RJ Parker he says half a carat 8:30

@ECM398 6 лет назад

uncut diamonds arent really worth all that much. Diamonds value are largely overinflated due to a huge part of the market basically being a monopoly. The 100 milligrams he had starting out would be somwhere between 1.5-2.5 dollars.

@FactsYall 6 лет назад

I know, but depending on quality and his source, the price could vary. Also, I'm sure he paid less than you or I would pay for half-carat earrings or the like from a retail jewelry store, as @Eric M stated.

@FactsYall 6 лет назад

Eric, that's a lot less than I would have guessed. Thanks for answering.

@mrhomescientist 6 лет назад

My initial vial was 5ct at $30, so the half carat I burned is only $3 worth. Good guess, Eric M!

@Flo_Resolution 3 года назад

@@mrhomescientist I've been wondering this for a couple of years. I know this might be a stupid question but... Can gold and diamond be melted together? I heard that metals and gems cannot melt together, from some ppl. But idk, I didn't see nothing specifically about gold & diamonds. I mean it's just Carbon (C) and Gold (Au). But I'm no genius on this.

@mrhomescientist 3 года назад

@@Flo_Resolution Carbon doesn't melt at atmospheric pressure, it sublimes (at insanely high temperature, about 10,000 F). You'd need insanely high pressure to liquefy it, and even then I think it's unlikely they would alloy together. No super expensive mixture for you, unfortunately.
