This indicates that the movement of the balls in the grinding jar causes the massive fracture of liquid mercury into microspheres, and thus increases the surface area available to react with the sulfur. The formation of an interface between the Hg microspheres and the sulfur leads to the reaction and formation of HgS (metacinnabar).
