Abstract

A fire log has one or several longitudinal incisions, which penetrate the log but do not reach the side surface and intersect in the log'"'"'s midsection. A lower part of the log has at least one air duct from the side surface to the log'"'"'s midsection in case the log is set on a surface which obstructs airflow to the log'"'"'s lower part. The log'"'"'s midsection contains an ignition device, which can be an ignition strip, tablet, briquette or other that has been permeated with an ecologically friendly flammable substance that burns fast and evenly.

Claims

1. A compact log having a longitudinal extent from end-to-end, a core midsection, a lower part and a side surface, wherein the log comprises:

a plurality of longitudinally extending, end-to-end incisions therethrough, wherein the incisions extend from a bottom surface of the log, intersect in the log'"'"'s core midsection and fail to extend to the log'"'"'s side surface; and

an air duct in the bottom surface of the log that extends from the log'"'"'s side surface to the core midsection of the log and fails to extend to the upper part of the log in order to avoid burning of the side surface of the log, wherein the air duct is configured as a groove, and wherein the air duct is radially offset from the incisions so that the air duct intersects the incisions only at the log'"'"'s core midsection and only adjacent the bottom surface of the log.

2. The compact log of claim 1, and further comprising:

an ignition device disposed in at least one of the incisions.

3. The compact log of claim 2 wherein the ignition device is impregnanted with a flammable substance.

4. The compact fire log of claim 3 wherein the flammable substance is a natural flammable substance.

5. The compact fire log of claim 2 wherein the incisions are filled with the ignition device.

6. The compact fire log of claim 2, and further comprising a plurality of said air ducts.

7. The compact fire log of claim 1 wherein the air duct extends along an end face of the log.

8. The compact fire log of claim 3 wherein the flammable substance is selected from the group consisting of stearine, paraffin and cooking oil.

9. The compact fire log of claim 1 further comprising a handle.

10. The compact fire log of claim 9 further comprising a fastener attached to the handle.
