Anybody want to take a guess what this really is?

Hint: field width about 15 mm.

I suspect this is mineral, rather than animal or vegetable.

A twig or root of a plant that was injured and resin has seeped out from the injury and hardened. This resin ridge, partly amber-like and translucent in appearance, bears the "mouth of the dragon's liar".

Or is that grey stuff on my "twig" mortar/concrete?

Looks like an orifice or unintended hole in a natural gas pipe that has collected combustion deposits around the opening. That would fit with the "fiery breath" that was observed, but what appliance, device it goes with/to...????

Well, following with the Charles combustion pipe hypothesis, according Betty resin idea, and in winter time...
...perhaps you are burning wood at home and the resin and gaz escapes from the wood when it is heavily heated (with orange tree and other woods it works)

In this case there was no participation by natural gas, wood, or other combustible organics. I'm not sure to what extent oxidation was involved in the "fiery breath" that I saw.

OK then... an electric heating coil or element of some type (but what? )

If the field width is about 15mm that would make the diameter of the part about 6-7mm. Perhaps about right for an electric oven element, but far too "messy" and...

How about the heating element from an old hot water heater? Don't know how you would have seen fiery breath (steam?) but you do some strange things Rik... Wink Wink Wink

I measure about 7.6 mm.

While I admit to doing some strange things, pressurized hot water snorkling is not one of them. Rolling Eyes

So nope, not a water heater. Not even some bizarre experiment involving a water heater. Good idea, though!

In fact I was stirring a pot of soup at the time... (Some of the previous guesses are getting quite close. Smile )

Here's a closer view, by the way. This was shot with a Nikon CFI BE Plan Achromat 4X NA 0.10, using EOS Utility to step focus on the tube lens. Illuminated by a desk lamp, shot with EFSC to avoid vibration blur.
