How hot would it need to be do fission a stable isotope of Potassium?

A temperature so hot that the atoms of the potato would violently collide into each other, probably at least tens of millions of degrees and you would need something to confine the potato plasma!

Maybe it’s fusion and potassium content increases?

Or you fuse potassium atoms into something heavier.
