Abstract
Abstract An artificial composite flammable firelog of generally pie segment shaped transverse cross section configuration including perpendicular flat sides interconnected by a convex third side. The log is preferably formed of a wax and wood particle composite. It may include fire retardant on the flat sides for selective burning on the curved side which faces the fireplace opening. At least two of such firelogs may be extruded simultaneously by use of a unique die member. Four such firelogs are conveniently packed in a rectangular box.

Claim 2
Dependent Claim
33 words
An artificial composite flammable firelog of generally pie segment shaped transverse cross section formed by two generally flat elongate substantially perpendicular intersecting sides and a third elongate curved side of predominantly convex configuration.
Claim 3
Dependent Claim
23 words
The firelog of claim 1 in which said curved side includes multiple spaced generally parallel grooves along the length of said curved side.
Claim 4
Dependent Claim
