You might find this interesting but I live in Ohio and are flint is famous for how it looks but a lot of the churt has enough iron in it to spark on itself it's way better with steel but the natives traded it throughout north and south america we have a lot of it in southwestern Ohio
Cerium is usually used for cigarette lighter 'flints'. In that case, it is actually the 'flint' rather than the steel which is producing the burning particles. Back when I was in the military, we had a training video on the hazards of diborane, though I'm fairly sure I never encountered it. Handling UDMH and iRFNA was frightening enough, thank you. re. the SR-71 - fuel bladders, people ... fuel bladders ...
Not sure about flint but here in southwestern Ohio the churt was prized by natives all over north and south america because it has enough iron in it that it will spark on itself or another piece of flint but it wont throw as much spark as striking it on iron its better than flint because the churt adds spark infact it was a big export for flintlock muskets because of it drastically improved ignition of the priming powder
The giveaway is in the name; Iron Pyrite! (etymology as per Pyro) iron (II) disulphide aka Fools Gold. Again; flint or chert as the cutting blade. The sparks are much dimmer (red-orange) than those of steel (bright orange) and the sun might need to have hit the horizon in order to see them, because they hold less energy: the catch tinder will need to be much more sensitive (eg Amadou made from hoof fungus). IP naturally oxidises in air so a fresh surface is required, details on the web of radial nodules as opposed to cubic crystals being preferable. :-j
Also, before matches were invented, people mostly kept fires going as much as possible. When traveling, they would carry a "fire bundle" with embers and enough combustibles to keep them smoldering. Bow drills, flint and steel or flint and pyrite were the backup, used only if the fire, in spite of their best efforts, went out.
It sounds like you say diborane. But everything I have read on the SR-71 state triethylborane (TEB) was used.
This guy knows EVERYTHING. 😅
I think this is my new favorite channel.
I just acquired a couple flintlock rifles, this video made how they work a bit more clear for me. Thanks!

Thank you😊
Good work
Superb background informations, that's really high quality content there! Thank you

so how did our ancestors make fire before the iron age, i could have sworn that banging 2 flints together would make sparks

They used hand drills and bow drills, wood against wood, to make embers. A lot of YT videos on this.
