The present invention provides various eodiments for a colored flame lamp and a colored flame candle. The lamps and candles may burn with a flame of a characteristic color such as green, red, blue, purple, orange, or silver-white. The lamp fuel composition may include a liquid solvent and dissolved metal salts. The candles may be composed of a solvent, a hardener, and metal salts dissolved

How to Make Stunning Colored Fire That''ll Leave Everyone

A fire flame is usually orange, yellow, red, or white in color, but when a chemical―generally metal salts―are added to the flame, their atomic emission spectra changes the frequencies of light radiation (visible light) and that change brings about colored flames, as we see them.

Colored flames - MEL Chemistry

Orange flame – sodium chloride. Red flame – calcium chloride. Light-violet flame – potassium chloride. Turquoise flame – copper sulfate. Blue flame – copper chloride or selenium. Light-green flame – borax. Pink flame – strontium chloride. Scarlet flame – lithium chloride. It’s worth noting that the flame’s color depends on the metal ion; the salt’s anion has practically no influence whatsoever.
