What would happen if a candle's wick was made out of glass instead of string?

I know the glass wouldn't decompose but I've seen a video with a candle with a glass wick and the flame is much higher why is this?

Er, are you sure you saw a candle with the wick itself made of glass?

The wick absorbs the melted wax and burns slowly.
Glass
a) doesn't burn
b) doesn't absorb wax

So I'm not sure what it is you actually saw in that video.

Yes our science lecturer showed us it at university.

Maybe that wasn't glass. Are you sure it's glass?

Can you link the video please.

Honestly, this seems weird. I though glass can't burn as it is silicon dioxide.
It can melt at extremely high temperatures, but I can't figure out how did it burn in the video.

Maybe it's coated with something (?). Your teacher didn't explain anything about it?

Apparently it's for us to research but I can't find anything on it!

Actually the wax is what burns not the wick. So probably it just appears to burn more when you use glass.

Any new ideas from you?
