What Causes This?

I noticed a candle I had lit was burning dim. When I looked in the melted candle wax around the wick, black flakes were moving constant. Can anyone explain to me why flakes of carbon were being pulled, and pushed from the wick? Sorry for the short post, I was just curious. I tried to Google it, but have no clue what to search. I will embed the video below.

If the candle is burning dim, then it isn't completely consuming the wick in a complete combustion cycle. If the wick were to be burned completely, the carbon would be converted into CO2. Instead, bits are cooling down and flaking off.

Incorrect links to youtube films? Otherwise I have no idea.

ETA Private, not now-working youtube films.

Next!

It was burning more dim before the video. I poured some wax out. It looked like the flakes that had already flaked off were being pulled to the wick and then pushed away; not new pieces flaking off of the wick. Thanks for the reply though!

I'm sorry, I don't mean to waste your time. Is the video not working? I know i embedded it properly.

Hmmm. I, too, and getting a message saying "This video is private".

Can you do something about that so we can add to the discussion?

I uploaded to youtube, copied everything after the '=' symbol, and clicked the youtube button above. How can I upload it differently?

The dim light is incomplete combustion
Creating the carbon flecks in the molten wax
The movement of them is due to convection
Currents in the wax between the surface
Close to the wick and the still solid
Layer at the edges hth

The video is "private", meaning that most of ATS without youtube accounts, or some possibly with, cannot watch the posted video!

It may not be an issue with the way you are linking it to ATS.

I think the problem is in the way the YouTube video itself was created and/or any "permission" options that it may have. You need to make the actual YouTube video publicly available for all to see.

Screw it.. I'm sorry guys, all I have is my mobile phone.
MODS please delete.

Don't ever apologize for trying to educate yourself. ......the wick is not burning correctly so it is dim, and flaking of particles into your wax....see the poster " storm cell" for the correct explanation!

Wasted time is not a problem here, unwatchable (due to access restrictions from YOUR account) videos are. As is your last attempt/upload.

"If the owner of this video has granted you access, please sign in."

Nope, I have no google/youtube account...

ETA: Learn how to post publicly accessible youtube films, otherwise your threads here will suffer considerably. Hope it helps!

those black flakes mean that the flame isn`t burning efficiently, lack of oxygen.

What you are witnessing is toroidial convection. Since the center is hotter than the edges, the interior particles are being pushed up and away from the flame. When they cool and began to sink (on the outer rim), they are then pulled back and up through he center once more.

You have to go to your YouTube Video Manager, click the blue button with a padlock and change the permissions from "Private" to "Public" or "Unlisted".
