An apparatus for coloring gas flames in gas-burning fireplaces so as to give the appearance of a wood-burning fireplace comprises a ceramic tube having a coating which causes colorization of gas flames when the coated tube is placed in the secondary reaction zone of a gas flame. Principle coating ingredients include sodium carbonate, aluminum oxide, pulverized soda lime glass, and sodium silicate. The coating is baked onto the ceramic tube, and, when located in the secondary reaction zone of a flame, will provide nearly constant natural color to a gas flame for periods in excess of 1000 hours.

A top burner for a gas cooking range includes a burner vent having a radially upwardly sloping wall surrounding the burner head. An annular ring projects upwardly from an inner radial extremity of the wall to direct combustion products from the burner head into immediate scrubbing contact with the bottom of a cooking utensil. The wall terminates at an outer radial extremity adapted to be located in sufficiently close proximity with the bottom of the cooking utensil to restrict radially outward flow of combustion products. Capture ports adjacent the outer radial extremity of the wall exhaust combustion products through a vent pipe to the atmosphere at a positive pressure. A range oven/broiler may also be connected to the vent pipe to provide a fully vented range.
