Liquid Sulphur Crystallization

[Uberownager]

@snogonesix It's a excellent question. This is molten sulphur cooling yes. In/at a volcano you will however not find pure elemental sulphur like this, since it is too unstable, especially at volcano temperatures. You will however find large quantities of sulphur dioxide gas (SO2) which is responsible for the smell people usually connect with sulphur. Iron sulphides (FeS2) and many other sulphurous minerals will probably be present aswell

[TheChemistLab]

EPIC :D

[PauldChemist]

=')

[fcguy7]

I've melted elemental sulphur before and it was blood red ... why is your not the same color? To me it appears to be a solution and we are watching the crystallization of sulphur out of that solution.

[Uberownager]

@fcguy7 Suplhur changes to a red color, upon excessive heating above the melting point, e.g. when the sulphur is burning. This is caused by a change of crystal structure

[lexichronicle2]

Really nice!

There are only three common things, to my knowledge, that expand when they solidify. Water, antimony and bismuth.

[ricko2001]

Any ideas on how to produce large crstals? (besides digging them up from the ground)

How about evaporation of a carbon disulfide solution of sulfur?

[OrbiliusVinnicus]

Mother Nature creates best pieces of art.

[toothpick93]

how do you get the solid piece out with out braking the glass

[xxeminemwhip]

nice man two thums up =]

[533ren335]

wouldn't extreme pressure build on the test tube?

[Uberownager]

@533ren335 It is not sealed ;)

[69iron69]

So was it super cooled? Is the video in real time?

[Uberownager]

@69iron69 Read the description before asking. It's just hot sulfur solidifying naturally

[pyrocrazyUSA]

sweet! im gonna do this, except i will pour it into a glass of water

[antiswattt2]

hey! :O hvor fik du fat i svovl???

[Uberownager]

Matas

[antiswattt2]

det nedern de ik sælger det mere i matas.. så ellers ca. 5 kg ammonium nitrat og svovl.. 119 kr.. men tror ik de sælger det mere fordi svovl nu er ulovligt D: eller matas sælger ikke mere

[chemistryplan]

@antiswattt2

Det er blevet ulovligt nu

[antiswattt2]

lol ja skrev jeg også XD har du prøvet kmno4 + mg flash?? 1:1

[flarn2006]

I've melted sulfur before, and it certainly doesn't smell beautiful.

[redtails]

A bit shaky, would have been awesome to see the crystallization from up-close in like.. a test-tube holder and a camera on a tripod

[TheHydroCircus]

Agreed. They should be burned and shot into space so they will not pollute our earth.

[neddy17]

you are wrong, they should be burned for fuel to melt the sulfur, then the remaining burnt religious person charcoal used to make gunpowder

[bathingapes112]

my church is like right next to a sulfur creek..and it smells TERRIBLE!!!

like really really bad old rotten eggs!

no lie !

[neddy17]

that is probably the stench of the rotten brains of the people who go to church

[TheHydroCircus]

ew a religous guy, i masterbaiteed and cam all over the bible.

[coolliger]

Your intelligence is shown not only by your religious stance, but by your ability to spell simple words.

You fail...

[elgranto7]

cool, i will try this!

[Theonewhoclimbs28]

I love the musical selection. I crack up a little whenever I hear it. What is it anyway?

[Uberownager]

It's called "Waltz of the Flowers" from the Nutcracker suite, by Tchaikovsky. It good :P

[ExplosiveScience]

That seemed less viscous and lighter in color than pure liquid sulfur.  And why didn't it oxidize, did you do it in an oxygen free environment or have an extremely controlled heat source?

[Uberownager]

It was indeed pure powdered sulphur, heated.

The heat source was a small butane blowtorch.

The melting point of sulphur is 115 degrees celcius, which is far below the autoignition temperature, as well as flashpoint. So no oxidation occures.

[johancs7]

Soluble in hot toluene...

[TheMojoTribe]

how did you put it in solution its insoluble

[Uberownager]

It's not a solution, it's pure melted sulphur.

Actually sulphur is soluble in carbon disulphide, AFAIK

[TheMojoTribe]

yey (drugy face look) me knows i thought you said it was in solution of h20 wops!! keep up the vids there good

[pyrogeniuses]

i always thought pure sulfur when melted makes a blue syrupy liquid

[kungfulicious2]

yeah its actually blue but he just used food colouring to make it yellow because i think his fav. colour is yellow, also yellow is easier to see the crystallisation.

[Uberownager]

... :P sulphur is yellow it's not food dye haha... The blue color only appears when sulphur is oxidizing

[starshock01]

it actually turns blood red

[metamaterial]

When it's on fire, it meets that description.

...Well, the flame is blue, at least. And the liquid is syrupy.

[fakestache]

I see you spelled sulfer right in your comment replys. Why not in the title?

[Uberownager]

"Sulfur (Sanskrit, sulvari; Latin sulfur or sulpur); The element has traditionally been spelled sulphur in the United Kingdom, Ireland, Hong Kong, the Commonwealth Caribbean and India, but sulfur in the United States, while both spellings are used in Australia, New Zealand and Canada"

[Uberownager]

And I assume "sulfer" as you spelled it, is supposed to be "sulfur" :P

[fakestache]

You're right I spelled it wrong, but I wasn't trying to be mean about it, I was just curious, but I guess it's like armor and armour.

[Uberownager]

Fair enough hehe. I just can't help myself.

But yeah, there's a lot of those funny differences. Armor/armour, color/colour and so on.

Not always easy to know what's what

[foorroms]

nice and so peacefull music

[trx636]

Ah, pretty wonderful.

[Morivar]

Very nice demonstration mate :)

[hinckleyforpresident]

Very cool.

You should try seeding the liquid at a very cold temp. Maybe then it would nearly instantly turn solid.

[counteryourface]

Isn't molten Sulfur blood red?

[Uberownager]

Only at it's decomposition temp, which is over 300 degrees I believe - i.e. when it is burning.

[Demodrus]

interesting

[piroflash93]

interesting...had no idea wat was actually happening besides sulfur crystalizing but still cool. can u explain it?

[Uberownager]

The sulfur was hot, around 130 celsius, and then it cools down to just below it's melting point.

And because the test-tube is clean, it is still liquid even below its melting point, since there are no crystals/impurities for the sulfur to cling on to.

[FrederikSOlesen]

Very nice. How did you make it crystallise? Temperature?

[Uberownager]

Indeed. I just captured the part were it starts "freezing"

[FrederikSOlesen]

What is the freezing point at?

[Uberownager]

The freezing/melting point is @110 celsius.

Så kan man bare lige prøve det :P
