2136648 9421969 PCTABS00033 Method and means for enhancing the visible length and color of high efficiency gas flames in an artificial gas log fireplace/gas burner system is characterized by selecting from a plurality of metallic salt compounds, compounds having a low melting point and the ability to exhibit light in the visible spectrum when the metallic salt compounds absorb energy from a gas flame. The metallic salt compounds are placed in a high temperature area of the burner system adjacent the gas flames so that at the melting point of the metallic salt an ionized vapor is generated which is directed into the path of the combustion air being supplied to the gas burner. The energy level of the ionized metallic salt compounds are elevated and when subsequently cooled, they emit light in the visible spectrum which combines with the gas flames and colors the invisible flame spectrum so that the invisible gas flames become visible and appear longer and exhibit natural colors.
