A burner for depositing carbon soot on a glassware mold includes a burner nozzle having an annular array of individual gas outlet ports, a fuel passage within the nozzle connected to a first plurality of the outlet ports and an oxidant passage in the nozzle connected to a second plurality of the outlet ports. The first plurality of outlet ports individually alternate with the second plurality of outlet ports around the annular array such that the array presents alternate fuel and oxidant outlet ports around the array. An ignition electrode is disposed on the burner nozzle within the annular array of outlet ports for igniting fuel and oxidant emerging from the outlet ports. The ignition electrode preferably is in the form of an elongated ignition electrode rod telescopically surrounded by an insulator and centered on the burner nozzle within the annular array of outlet ports, and a ground electrode telescopically surrounding the insulator. The ground electrode preferably is part of the burner nozzle and is electrically connected to a burner mounting block on which the burner nozzle is mounted.
