no propane burners. propane freezes solid at minus 60°, and you need heaters to get any flow long before it gets that cold, to the point that you can set propane out in a bucket, which I have some experience with in useing it, to supper cool transmission shafts, so that they shrink, and press fit bearings slip right on.
so yes they have propane, but they use it in other, less well known ways.
Propane does not freeze anywhere near -60C. Wikipedia [1] says it freezes (liquid to solid) below -187C and boils (liquid to gas) above -42C.
Propane is probably unusable as a fuel below -42C because there is no vapor leaving the tank [not within my experience]. That is different from the propane being a solid.
Well, locals called it propane, but I didn't exactly "send it to trace for analysis."
Generally, you (and your toolbox) only spent a few minutes out of every working hour outside. And your toolbox would definitely be room-temperature initially and not cool down to anywhere near ambient temperature while out.
Butane stops vaporizing at -1C (31F), isobutane at about -10C (10F). Propane's boiling point is even better, at about -40C/-40F, but it self-cools and doesn't develop the required pressures to run a torch.
I know this because my otherwise dependable camp stove is a 3-season affair. For winter camping, you basically need a white gas system (liquid fueled, manually pressurized or gravity fed).
I suppose I'd reach for an acetylene torch in a cold workshop.
