The flash point is different. The flash point is the temperature that is necessary to create enough vapor for the substance to ignite.
Flammable material has a low flash point, which means it catches on fire easily. Think gasoline. Combustibles need a higher initial temperature, but eventually they will burn and sustain the burning until running out. Think wood.

They’re referring to the relationship between surface area and combustion. Talc, for example, melts but does not burn. Talc powder can ignite if blown over an open flame.

My first thought was: “I must try this”. I need to read my house insurance policy first.
Curiosity got the better of me when I waved an alcohol wipe over an open flame. There’s still a dark mark on the office carpet tile from where I had to stamp it out

Please invest in a fire blanket and keep it near by when you do stupid things with fire.

Mine paid for itself the first time a flame got out of control while I was having some fun. No lasting burns to human or objects in my office lol.

Keep away from dust explosions, they are very uncontrollable because they ignite very fast and produce a lot of heat. It’s technically not an explosion, but it definitely is an easy way to burn your house down.

Mythbusters did this with coffee whitener as I recall. Impressive.
This has also happened to sawmills and flour mills, under less controlled circumstances.

Let it be someone else’s carpet. Or in this case, driveway.
