  • Method and apparatus for producing a wood-like flame appearance from a fireplace-type gas burner
    Patent number: 4992041
    Abstract: 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.
