Abstract
A flame coloring device makes a flame, such as a flame from a propane burner, visible even when the burner is used outdoors or in a bright environment. The device includes a carrier adapted for placement on the burner barrel and a solid colorant emitter such as sodium chloride supported by the carrier. When the carrier and colorant emitter are heated by the burner flame, the emitter emits a material that provides visible light, thereby defining the flame.
