1. An electrode assembly for controlling the electrosurgical arc current from an electrosurgical generator, the electrode assembly comprising:

  • an electrode having a conductive surface adapted to connect to a source of electrosurgical energy, said electrode including a width and a length; and

    a non-conductive, porous ceramic material substantially coating said conductive electrode, said non-conductive, porous ceramic material having a thickness and including a plurality of pores dispersed therein having a diameter and a depth, said non-conductive, porous ceramic material varying in thickness across at least one of the length and width of the electrode;

    wherein upon activation of the electrosurgical energy source, electrosurgical energy creates an initial arc current across the conductive surface of the electrode.
