Its heat transfer capabilities are superb, but it's also an electrical conductor — an extremely good one, in fact. Hexagonal boron nitride (h-BN)

Here we see why humans unwittingly build fires that look the same: edifices of fuel, as tall as they are wide. The pile of fuel is permeable, air invades it by natural convection and drives the combustion. I show that the hottest pile of burning fuel occurs when the height of the pile is roughly the same as its base diameter.
