Abstract
An improved method of imparting colors to fires in home fireplaces is described as well as the preparation of the materials used to provide said color. Metal salts which impart color to flames are granulated using hydrated alkali metal silicate as a binder. When these granules are added to fires, the silicate binder softens on contact with warm or hot combustible material. The silicate then loses water and is transformed to a solid once more so that the material becomes bonded to the combustibles. Upon burning the metal salts are decomposed and the flames are colored. The system is very efficient and proper application requires the use of bulking agents in the granules.
