An artificial firelog comprising a mixture of combustible materials and a combustible binder further contains particulate coke comprising about 1% to about 35% by weight of the firelog, the coke particles having a size less than about 4 mm, to create a realistic crackling sound that mimics the sounds produced during the burning of natural logs. The particulate coke has a preferred moisture content between about 2% and about 20% by weight. The particulate coke may be combined in predetermined ratios with other established crackle additives including natural additives such as coriander seed to extend the time period during which the burning artificial firelog crackles. Preferably, the particulate coke comprises metallurgical coke.
An artificial firelog comprising combustible materials, a combustible binder and an effective amount of a sound generating additive to provide a crackling sound during at least a portion of the burning of the firelog wherein the sound generating additive comprises particles of coke and wherein the particles of coke comprise particles of metallurgical coke.
An artificial firelog comprising combustible materials, a combustible binder and an effective amount of a sound generating additive to provide a crackling sound during at least a portion of the burning of the firelog wherein the sound generating additive comprises particles of metallurgical coke and wherein the particles of metallurgical coke have a moisture content between about 2% and about 20% by weight.
An artificial firelog comprising combustible materials, a combustible binder and an effective amount of a sound generating additive to provide a crackling sound during at least a portion of the burning of the firelog wherein the sound generating additive comprises particles of metallurgical coke and wherein the addition range of the particles of metallurgical coke is between about 1% and about 35% by weight of the firelog on a dry basis.
An artificial firelog comprising combustible materials, a combustible binder and an effective amount of a sound generating additive to provide a crackling sound during at least a portion of the burning of the firelog wherein the sound generating additive comprises particles of coke and at least one sound generating natural seed.
An artificial firelog formed from a mixture of cellulosic material and a wax binder comprising from about 25% to about 39% by weight of a cellulosic material and from about 40% to about 60% by weight of a flammable wax binder, the artificial log further comprising from about 1% to about 35% by weight of the firelog of metallurgical coke particles, the particles having a size less than about 4 mm.
