Kashering a Real Marble Countertop

Question

I have a real marble countertop in my kitchen. Is it possible to kasher the countertop itself without covering it, and if so, by which method: irui (pouring boiling water), libun (burning/heating), or some other way?

Answer

Shalom u-vracha. 

One who does not wish to cover the countertop may clean it thoroughly, pour boiling water from a kli rishon (the first vessel that was on the fire) onto a heated stone, and then pass the stone over the entire surface of the countertop.

This option applies only to real marble, and not to synthetic stone such as Caesarstone and the like.
