Yes the rock gives off FIR when heated and so does sand.The heating pad is made
of plastic cloth and wire so it does not have much material there to give off
fir. It probably gives off some but not as much as rock does, If you look at all
the mineral lamps on the market they all have a heating source and then a
mineral plate of some sort that gives off the FIR. Granite is good for this as
it contains several different minerals in it.
