An invention is provided for a spiral flame torch apparatus. The spiral flame torch apparatus generally includes a base having a bottom plate, lower stabilization plate, and an upper stabilization plate. Situated on the base is a glass halo comprised of a plurality of rounded glass sheets. The glass sheets each include vertical sides that overlap one the vertical side of another rounded glass sheet, leaving gaps between the sheets. Disposed within the glass halo is a paraffin based flame source having a large wick disposed centrally within the flame source.

Aspects and features of a burner for a cooking appliance include a first plate defining flame ports arranged in flow-sharing groups around a periphery of a combustion surface and a second plate coextensive with the first plate. Each plate is contoured so that the plates define an annular void within the burner. The annular void is fluidly coupled to the flame ports. In some aspects, each flow-sharing group includes clusters of flame ports, with each cluster including flame ports of two different diameters. The plates can each be made using the same tool such as a die, stamp, or mold, and the burner can be sized and installed in a cooking appliance so that it extends to cover a large portion of a wall of the cooking cavity of the appliance.

A gas torch includes a base couplable to a gas source supplying gaseous fuel and gas ports formed in a top surface of the base to emit gas upwardly therefrom. A plurality of diverters is stacked in a spaced apart relationship directly above the base, each diverter having an inner edge and an outer edge. Each diverter is positioned above a lower diverter so that the inner edge and the outer edge are positioned intermediate one of the inner edge and the outer edge of the lower diverter. The lowest diverter, that which is adjacent the base, is positioned such that the gas ports are positioned directly underlying and intermediate the inner edge and the outer edge thereof.
