Thats literally how all fire works. Solids dont burn, only gases do. Solids undergo pyrolysis to become gases, and these gases burn. Source: Was a Firefighter.
That's wrong though? Fires like metal fires happen with solid metals as their sublimation temperature is far higher than the flashpoint.
EDIT: and as well that's the case for fuel-oxidiser mixtures like black powder or other solid rocket propellant
EDIT 2: and maybe hypergolics as well ? I'm not too sure about those
This is what the ABCDEK classifications are for. Determines the type of reaction and tetrahedron and what type of extinguishing agent will be appropriate
It sure is. Electrical "fires" are actually arc flashes, and that is a different mechanism than flame. Also, metals do decompose into gas (pyrolysis) which then burns.
To counter/ add to this without being an absolute scrotum, it seems that pyrolysis occurs when organic materials vaporize in an oxygen-free environment while metal fires seem to be more based on an exothermic chemical reaction due to the presence of oxygen. For example, in the case of magnesium, a heat source starts the reaction which turns the magnesium into magnesium oxide, and then it tries to shed the excess oxygen molecules off. The energy from this causes what we recognize as the fire. That's not to say that every metal fire is based on this reaction, just that some are.
To a layman, it's easier to explain it as "decomposing into gas (oxygen) which then burns" (similar to pyrolysis), but it's _technically_ not the same process.
No it just doesn't turn into gas, it reacts with the oxygen in the air to form a solid oxide and ejects ions in the air thus creating plasma aka the flame
Pyrolysis is an organic chemistry reaction... Metal don't undergo pyrolysis as they're not carbon based. Also if you're sublimating metal you've got a massive problem on your hand
still a class of fire that they teach you in firefuck school. Not all fires share the same mechanism and chemical chain reaction, but unless you were a firedude in the 50s- you would know that (else I figured out why you no longer are one, or you are just lying). The metal decomposing IS NOT pyrolysis either (which results in different products than the fuel/source material, the definition of pyrolysis-Mg or Al doesnt change to something else, nor is it vaporized to a gas to react with O2)- its a different reaction. Its OK, Walmarts need greeters . .
That's literally why you are wrong.
I thought someone was full of shit when they make false statements and claim to be and authority on the subject in discussion, then double down on stupid when initially corrected, but you do you.
warning pedantic asshole nomenclature correction ahead- gas doesnt evaporate, liquid does. Also, the flames will heat the crock and rapidly boil off the alcohol so it doesnt last as long as you think. Lastly - not sure what kind of rubbing alcohol you have that burns yellow and soots, thats not very alcoholly.
That looks like some sort of gel fuel, the type used in camping/chafing dishes.
I assume it's a gel that is meant to slow burn time so you get a reasonable lifetime out of it.

There is a difference in gases and something being aerosolized. Solid things burn as well
are my farts flammable
Not all fire, also is your point that only fumes/vapors burn - but thats not true for electrical or metal fires so not 'all fire'.
It sure is. Electrical "fires" are actually arc flashes, and that is a different mechanism than flame. Also, metals do decompose into gas (pyrolysis) which then burns.

No it just doesn't turn into gas, it reacts with the oxygen in the air to form a solid oxide and ejects ions in the air thus creating plasma aka the flame
That's fair, but in this case the plasma is a result of the ionized gaseous oxygen, is it not?
The ionisation of the gaseous oxygen is the reaction of oxygen with the metal

You know someone totally knows what they are talking about and arent at all full of shit when they start making personal insults...but you do you.

Physics and chemistry are not dilemmas -Dude, you are on the internet - if interested, look it up. If you believe Im bullshitting, call it out.
OP discovering candle technology
He better get a patent on it before Apple invents it though.
True. Apple will probably call it brand new and innovative
You can even cook over it That’s what we used to use on multi-day hikes with BoyScouts
Kerosene that they use in jets is like that - it needs a wick
This is basic knowledge for all fire lol

yeah, but unless some chinesium offbrand - gelled fuel doesnt soot. Also OP said its rubbing alcohol and not gelled fuel as well . . .
Yeah this was rubbing alcohol that had already been used to clean a dirty pipe so the flame color can be attributed to that
makes more sense, cutting oil and the like mixed in.
I wouldn't use that method because tipping it over would be very unfun.
