A spark plug (100) includes a ground electrode (125), a firing electrode (115), an insulator core (105) having an insulator core nose (120), and an outer shell (110) surrounding the insulator core (105). The improvement includes the insulator core nose (120) including a high temperature glaze applied to an outer surface of the insulator core nose (120) and the high temperature glaze composition. The composition includes, by weight:

Anti-carbon fouling spark plug

A method of affixing a precious metal to an electrode includes placing a length edge of a generally cylindrical, precious metal wire on an electrode surface and resistance welding the wire to the electrode surface. The precious metal may include platinum.
