An artificial fireplace log containing pyrogenic coloring matter which produces colored flames upon ignition of the log continuously until the log is consumed. The log is composed of combustible materials, preferably sawdust and wax, and contains pyrogenic coloring matter distributed throughout the log mix. Additional pyrogenic coloring matter is adhered to the surface of the log, preferably along two adjacent longitudinal sides corresponding to the top and front of the log as it is positioned in a fireplace. The process of the invention includes the steps of preparing an artificial log mix containing pyrogenic coloring matter, molding an artificial log with the mix, and adhering pyrogenic coloring matter, preferably in the form of dry, finely-divided particles, along the surface of the log. |

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT As shown in FIG.
1, a log 10 of the invention is customarily cylindrical in form and is composed primarily of combustible materials admixed with flame coloring matter.
Preferably dry, discrete particles of additional pyrogenic coloring matter 11 are distributed over the surface of the log and adhered thereto.
In FIG.
2, the preferred log 20 of the invention has a flat surface 21 which acts as the bottom of the log when it is placed on a grate 22 in a fireplace.
The log is thereby prevented from rolling out of position as when placed on a grate or when partially burned.
As illustrated in FIG.
3, a log 30 having a flat bottom 31 serves the additionally important function of providing a reference point for positioning the log in a fireplace when only the top 32 and front sides 33 of the log 30 have adherent particles of pyrogenic coloring matter 34.
The resulting colored flames (not shown) along the top 32 and front sides 33 of the log 30, when burned, are seen from the front of the fireplace (not shown).
The rear side 35 of the log 30 does not have particles of pyrogenic coloring matter adhered to its surface.
If it is desired to wrap such a log in paper or other combustible material for purposes of marketing, directions as to placement of the log in the fireplace to achieve maximum exposure of the colored flames can be printed clearly on the wrapping material which is left on the log and serves as an aid to igniting th log.
Although the traditional log-shaped artificial log having a flat surface along one longitudinal side is preferred from both a practical and an aesthetic standpoint, it is also within the contemplation of the invention that such artificial logs may take other shapes and forms.
For example, as illustrated in FIG.
4, the log may take the form of a briquette 40 having a flat top 41, a flat bottom 42, and a flat front side 43.
In this embodiment, the particles of pyrogenic coloring matter 44 can be adhered to the top 41 and front 43 of the briquette 40
